How to Get Substring from a String in Python using string slicing

We can make use of string slicing to get the substring from a string in Python.

Syntax:

string[start:end:step]

• start: Indicates the beginning of a string. default: 0
• end: indicates the endo fo the string. default: length of the string
• step: indicates consecutive elements. default: 1

Let's say we have a string "I am learning Python" and we want to get the strings at the first and last index in this sentence as a substring.

>>> sentence = "I am learning Python"
>>> first_word = sentence[:sentence.index(' ')]
>>> print(first_word)
I
>>> 
>>> last_word = sentence[sentence.rindex(' ') + 1:]
>>> print(last_word)
Python
>>> 

More Examples:

>>> string = "I Love Python"
>>> 
>>> substring1 = string[2:6]
>>> print(substring1)
Love
>>> 
>>> substring2 = string[2:]
>>> print(substring2)
Love Python
>>> 
>>> 
>>> substring3 = string[:6]
>>> print(substring3)
I Love
>>> 
>>> substring4 = string[::2]
>>> print(substring4)
