Summary: You can use one of the following methods to split a string after the delimiter –

• Using split
• Using string slicing
• Using regex
• Using partition
• Using removeprefix

Minimal Example

# Given String

chat = "Python Founder: Guido van Rossum"

# Method 1

print(chat.split(':')[1])

# Method 2

print(chat[chat.index(":")+1:])

# Method 3

import re

print(re.findall(":(.*)", chat)[0])

# Method 4

print(chat.partition(':')[2])

# Method 5

print(chat.removeprefix('Python Founder:'))

Problem Formulation

 Problem: Given a string; How will you split the string after the delimiter? The output must only contain the substring after the delimiter.

Example

Let’s visualize the problem with the help of an example:

# Input

text = "Subscribe to - Finxter"

# Expected Output

Finxter

Method 1: Using split()

Approach: First, we will simply split thestring using “-” as the delimiter. Next, to extract the string before the delimiter we will use the index of the required substring. As the split() function returns a list of substrings, we can extract the last part using list indexing [1] (Indexing starts at 0).

Code:

text = "Subscribe to - Finxter"

res = text.split('-')[1]

print(res)

# Finxter

Note: The split() function splits the string at a given separator and returns a split list of substrings. It returns a list of the words in the string, using sep as the delimiter string.

Method 2: Using String Slicing

Prerequisite: String slicing is a concept of carving out a substring from a given string. Use slicing notation s[start:stop:step] to access every step-th element starting from index start (included) and ending in index stop (excluded). All three arguments are optional, so you can skip them to use the default values.

Approach: First, we will use the index() method to find the occurrence of the delimiter in the text. Next, we will slice the string from the index next to the index of the delimiter until the end of the string. Note that we are starting from the index of the delimiter+1 because we don’t want to include it in the final output.

Code:

text = "Subscribe to - Finxter"

res = text[text.index("-")+1:]

print(res) # Finxter

Note:

The index()  method is used to return the index of the first occurrence of the specified substring, like find() but it raises a ValueError if the substring is not found.

Method 3: Using regex

The re.match(pattern, string) method returns a match object if the pattern matches at the beginning of the string. The match object contains useful information such as the matching groups and the matching positions.

Approach: Use the expression re.findall("-(.*)", given_string) to match and store all characters that come after the “-“.

Code:

import re text = "Subscribe to - Finxter"

print(re.findall("-(.*)", text)[0]) # Finxter

Method 4: Using partition

The partition() method searches for a separator substring and returns a tuple with three strings: (1) everything before the separator, (2) the separator itself, and (3) everything after it. It then returns a tuple with the same three strings.

Approach: We have used the partition method and used “-” as a separator. As we only need the substring before the delimiter, we have used the index of the required substring on the returned tuple and just printed the third element of the tuple (everything before the separator).

Code:

text = "Subscribe to - Finxter"

res = text.partition('-')[2]

print(res) # Finxter

Method 5: Using removeprefix

If you are using Python 3.9 or above then Python facilitates you with the removeprefix method that allows you to remove the substring that comes before a specified substring. Here’s a quick look at how the removeprefix method works –

Code:

text = "Subscribe to - Finxter"

print(text.removeprefix('Subscribe to -')) # Finxter

In this article, I’ll show you three simple habits to get way more done, have a much easier and stress-free life, and make more money. Almost guaranteed. Based on science!

But there’s a catch: these habits are often tough to implement for employees. I know because I have been there and done that.

When I finally created my own freelance-based business as a coder, all people in my environment were employees, and, unfortunately, nobody I knew implemented them. So I almost missed them!

~~~

Here are the three daily habits that will increase the quality of your life and your success as a coder:

Habit #1 – Work from home

People think commute time is not a big deal.

In truth, commute time ranks among the most expensive things you can do and is highly detrimental to your financial success and your happiness.

Let’s start with happiness:

In a 2019 paper titled “How commuting affects subjective wellbeing”, researchers showed that long commute times reduce your happiness and can lead to mental issues like depression:

“It is found that longer commute times are associated with lower job and leisure time satisfaction, increased strain and poorer mental health.”

I could provide many more sources showing similar results, but let’s move on to the financial and time impact.

The average one-way commute time for Americans is 27.6 minutes, according to the Census Bureau.

In a year with 260 working days, that’s a whopping 240 hours of reduced productivity that is stressful and reduces your work energy.

For employees, you could argue it doesn’t matter. But as a self-employed freelancer, you could work 240 hours with an average freelance developer income of $50 that’s a $12,000 annual time opportunity cost.

Over a working life of only 30 years, contributing $6,000 to a passive index fund (ETF) at an average 10% annual yield would result in a whopping $1,136,118 nest egg.

You may miss out on becoming a millionaire just because of one hour per day in commute time!

Okay, let’s assume you’re stuck in the conventional mindset of believing your time is “free” and it doesn’t matter.

Question: How much does the commute time actually cost in hard dollars without considering opportunity time costs and the drain of energy and happiness?

The average American commutes 41 miles a day to and from work (US Censor Bureau).

The average cost per mile of driving a car is $0.58, according to the US Department of Energy.

So, the direct annual costs of commute time are 41 miles per day times $0.58 times 260 working days equals $6,182.

Thus, over 30 working years, here’s another missed $1.1 million USD nest egg if you’re the average American employee!

(See previous calculations.)

Summary Commute: As an online freelance developer working from home, you’d easily pick up that $3.3 million USD over 30 years — just from saving commute time and investing the difference in the stock market.

And you’d be happier too!

But are there more simple gains you could add on top of those?

Yes, they exist! Let’s look at the second easy productivity habit that’s easy for freelancers but often tough to implement for employees!

Habit #3 – Have a 30-Minute Nap at Noon.

I sleep for half an hour every day at noon. My wife is from Spain, and it’s normal for my wife’s Spanish family to take a long siesta at noon.

Instead of plowing through a long 8-hour day until exhaustion, they work a couple of hours in the morning, sleep and recharge, and work for a couple of hours in the evening.

I love it – my quality of life has skyrocketed since I implemented this habit into my daily life.

And I became much more productive too.

Now you may ask: Is there scientific evidence on the benefits of daily afternoon naps?

You bet there is! In fact, there are too many studies to count. Here’s one:

In a popular MIT paper titled “The Economic Consequences of Increasing Sleep Among the Urban Poor,” researchers found that after more than three weeks of daily 30-minute naps, employees were more productive and invested more of their money into savings accounts.

Another paper titled “Effects of a Short Daytime Nap on the Cognitive Performance” demonstrated that napping in the afternoon improved all types of cognitive performance.

One study showed that the performance was improved by at least 2%, even considering the lost time through sleep. Although I believe taking a nap is way more beneficial than that if you’re a knowledge worker (=coder), let’s work with 2%.

2% of an average coding income of $100,000 USD yields an additional income of at least $2,000 per year. Put into the S&P 500, this yields an additional net worth of almost $400,000 USD after 30 years.

For sleeping…

Other results of similar studies are that people who take a daily nap are happier and healthier.

Not surprising results – but all the more powerful! And almost nobody is doing it!

Is it because today’s work environments have not yet caught up to the research? Maybe.

As a freelance developer, you can implement this simple habit in an instant — and make more money, be happier and healthier – just by sprinkling a little bit of sleep into your day!

Habit #3 – Go For a Morning Walk in Nature and Listen to Business Books.

There is strong scientific evidence for the benefits of daily walking, such as

“For every 2,000 steps, risk of heart disease, cancer, and premature death decreases by 10% […]” – with some convergence at the 10,000 steps per day level.

Also, walking in nature increases your work productivity and creativity:

“In 2014, two Stanford University researchers published some remarkable findings in a paper titled “Give your ideas some legs: the positive effect of walking on creative thinking”. […]

The results identified a clear link between walking and higher performance on the tests. In fact, compared to sitting, walking increased participants’ creative output by around 60 percent.”

Now, let’s layer in listening to business books on a daily basis while doing the walk.

From personal experience, I know that productivity goes through the roof as you keep compounding your business knowledge by reading business books.

It can easily increase your business results by double-digit percentage points every single year!

Let’s assume a mere 10% productivity increase from walking and listening to business books daily. (I think it’ll be 10 times that but let’s stay conservative).

As a freelance developer, your income will jump by $10,000 per year (or more). Over a 30-year life investing the difference in the S&P 500, yields a whopping $2,000,000 net worth.

And that’s not considering all the health benefits, reduced health costs, and increased life satisfaction when going for a walk daily.

Summing It Up

If you implement habits (1), (2), and (3), that is, you work from home, take a nap daily, and go for a daily walk listening to business books, you can accumulate an additional fortune of $2.2M + $0.4M + $2M = $4.6M USD.

Now read again, and look how easy these habits are! Indeed, they are fun!

And your quality of life and health will improve – it may add years to your life expectancy! Low-hanging fruits, right?

To your success!
