The count() is a built-in function in Python. It will return the total count of a given element in a string. The counting begins from the start of the string till the end. It is also possible to specify the start and end index from where you want the search to begin.
In this Python tutorial, you will learn:
Python count function syntax:
string.count(char or substring, start, end)
The count() method will return an integer value, i.e., the count of the given element from the given string. It returns a 0 if the value is not found in the given string.
The following example shows the working of count() function on a string.
str1 = "Hello World" str_count1 = str1.count('o') # counting the character “o” in the givenstring print("The count of 'o' is", str_count1) str_count2 = str1.count('o', 0,5) print("The count of 'o' usingstart/end is", str_count2)
Output:
The count of 'o' is 2 The count of 'o' usingstart/end is 1
The following example shows the occurrence of a character in a given string as well as in by using the start/end index.
str1 = "Welcome to Guru99 Tutorials!" str_count1 = str1.count('u') # counting the character “u” in the given string print("The count of 'u' is", str_count1) str_count2 = str1.count('u', 6,15) print("The count of 'u' usingstart/end is", str_count2)
Output:
The count of 'u' is 3 The count of 'u' usingstart/end is 2
Following example shows the occurrence of substring in a givenstring as well as usingstart/endindex.
str1 = "Welcome to Guru99 - Free Training Tutorials and Videos for IT Courses" str_count1 = str1.count('to') # counting the substring “to” in the givenstring print("The count of 'to' is", str_count1) str_count2 = str1.count('to', 6,15) print("The count of 'to' usingstart/end is", str_count2)
Output:
The count of 'to' is 2 The count of 'to' usingstart/end is 1
