In this article, we would like to show you how to count character occurrences in Python.

Quick solution:

text = "ABCBA"
result = text.count("A")

print(result)  # 2

 

1. Practical example using string count() method

Syntax:

str.count(substring)

Where:

  • substring - Required argument. The string we search for.

Example:

In this example, we use count() method to count the number of the "A" character occurrences in the text string.

text = "ABCBA"
result = text.count("A")

print('The number of "A" characters: ', result)  # 2

Output:

The number of "A" characters:  2

2. Practical example using count() method with optional arguments

Syntax:

str.count(substring[, start[, end]])

Where:

  • start - Optional argument. The index from which to start counting (by default start of the string, index 0).
  • end - Optional argument. The end index for the search (by default end of the string).

Example:

In this example, we use the count() method with optional arguments to count the number of the "A" character occurrences in the text string between index 2 and the end of the string (by default).

text = 'ABCBA'
result = text.count('A', 2, )

print('The number of "A" characters: ', result)  # 1

Output:

The number of "A" characters:  1
