points
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
