Count character occurrences in a given word, phase or sentence

Here we will learn how to write a program in Python which prints the number of occurrences of each character in a string.

There are multiple ways in Python, we are going to use Counter method.

Introduction to Python Counter

Python provides a counter class that is the subclass of the collections modules. It is a special class of object data . The container data types that are part of the Collections module. The counter subclass is generally used for counting the hashable objects.

To make use of Counter we need to import it first as shown in the below given example:

from collections import Counter

In the example below, a string is passed to Counter. It returns dictionary format, with key/value pair where the key is the element and value is the count. It also considers space as an element and gives the count of spaces in the string.

first lets Enter word , for example " Tahani", then a phase " due to avoiding chocolate" and then sentence " I always wanted to become a writer."

from collections import Counter

# inter your text 

in_txt = str(input("Enter your text"))

# using collections.Counter() to get 
# count of each element in string
oup= Counter(in_str)

# printing result 

print("Occurrence of all characters on your text is :\n"+ str(oup))

output 1:

Occurrence of all characters in your text is :
 Counter({'a': 2, 'T': 1, 'h': 1, 'n': 1, 'i': 1})

output 2:

Occurrence of all characters in your text is :
 Counter({'o': 4, ' ': 3, 'd': 2, 'e': 2, 't': 2, 'a': 2, 'i': 2, 'c': 2, 'u': 1, 'v': 1, 'n': 1, 'g': 1, 'h': 1, 'l': 1})

output 3:

Occurrence of all characters in your text is :
 Counter({' ': 6, 'a': 4, 'e': 4, 'w': 3, 't': 3, 'o': 2, 'r': 2, 'I': 1, 'l': 1, 'y': 1, 's': 1, 'n': 1, 'd': 1, 'b': 1, 'c': 1, 'm': 1, 'i': 1})
