Python String partition() method

The partition() method in Python searches for the first occurence of the specified string and splits the string into a tuple containing three elements.

  1. The first element - Contains the part before the specified string.
  2. The second element - Contains the specified string.
  3. The third element - Contains the part after the string.
Syntax of partition() method
string.partition(value)

value: The substring to partition on
Example 1

Code

str1 = "Pylenin loves Python"
print(str1.partition("loves"))

Output

('Pylenin ', 'loves', ' Python')
Example 2 - When the substring doesn’t exist

Code

str1 = "Pylenin loves Python"
print(str1.partition("cake"))

Output

('Pylenin loves Python', '', '')

As you can see, it returned the entire string as first element of the tuple and the last 2 elements are empty strings. The partition() method doesn’t throw any error if it is unable to find the substring.

Example 3 - When the substring occurs multiple times

Code

str1 = "Pylenin loves Python and Python loves Pylenin"
print(str1.partition("Python"))

Output

('Pylenin loves ', 'Python', ' and Python loves Pylenin')

The partition() method separates at the first occurence of the provided substring.
