Get a Substring From a String in Python

Hello friends, today I will show you how to get a substring from a string in Python. I have used a method called slicing. It uses the index for each character.

Fetch a Substring From a String in Python

The syntax for slicing is:

string[start:end:step]

Here,

•  ‘string‘ is the variable storing our value.
• ‘start‘ is the index of the character from where you want to begin the substring. By default, it is 0.
• ‘end‘ is the index of the last character of the substring from the string. By default, it is the last character’s index.
• ‘step‘ is the number of index values you want to skip. By default, it is 1

Examples

1 . Let’s take a variable Str with the value “CodeSpeedy”.

Code :

Str = "CodeSpeedy"
Substr = Str[1:8]

print(Substr)

As you know indexing starts from 0. In this example, I’ve tried to retrieve a substring from the 1st character to the (8 – 1) i.e. the 7th character.

Output : 

odeSpee

2 . Let’s take this situation where I don’t know the end value, then all you need to provide is the starting index.

Code :

Substr = Str[1:]

print(Substr)

Here you’ll get the substring value from the the starting index mentioned by you to the last character of the string.

Output : 

odeSpeedy

Now you know how to get a substring from a string in Python.
