String Count() Method in Python



Hello guys! Welcome back to another section of my tutorial on Python. In this tutorial guide, we are going to be discussing about the Python String Count() method.

The Python String count() method returns the number of occurrences of substring sub in the range [start, end]. Optional arguments start and end are interpreted as in the slice notation.

Syntax

The following below is the syntax for the Python String count() method -

str.count(sub,  start = 0, end = len(string) )


Parameter Details

  • sub - This is a substring to be searched.
  • start - The search starts from this index. First character starts from 0 index. By default search starts from 0 index.
  • end - The search ends from this index. The first character starts from 0 index. By default search ends at the last index.

Return Value

Returns the number of occurrences of substring sub in the range [start, end].

Example

The following below is a simple example -

#!/usr/bin/python

str = "this is string example....wow!!!";

sub = "i";
print "str.count(sub, 4, 40) : ", str.count(sub, 4, 40)
sub = "wow";
print "str.count(sub) : ", str.count(sub)

Output
Below is the output of the above example -

str.count(sub, 4, 40) :  2
str.count(sub) :  1
