# Frequency of each character in a Python String

If you want to get the frequency of each character in a Python string, you can use one of the methods listed in this post.
``````from collections import Counter

my_string = "congratulations"

result = Counter(my_string)

print(dict(result))``````
##### Output
{'c': 1, 'o': 2, 'n': 2, 'g': 1, 'r': 1, 'a': 2, 't': 2, 'u': 1, 'l': 1, 'i': 1, 's': 1}

The frequency of character in a string means how many times each character is repeated in the string. If you are using Python and want to get the frequency count of each character in a string, you can use the below methods.

## Using Counter() function of collection module

The Counter() method from the Python collection module can be used to count the frequency of each character in a string.

Code Example

``````from collections import Counter

d_str = "devsheet"

result = Counter(d_str)

print(dict(result))``````

Output

``{'d': 1, 'e': 3, 'v': 1, 's': 1, 'h': 1, 't': 1}``

## Count each character frequency using For Loop

To calculate the frequency of each character, we can also use Python for loop without using any functions(). This is a native method to get the each character count in a String.

Code Example

``````my_string = "devsheet"
char_frequencies = {}

for i in my_string:
if i in char_frequencies:
char_frequencies[i] += 1
else:
char_frequencies[i] = 1

print(char_frequencies)``````

Output

``{'d': 1, 'e': 3, 'v': 1, 's': 1, 'h': 1, 't': 1}``

## Using get() function

We can also get the dictionary that contains the count of each character in a String using the get() function in Python.

Code Example

``````my_string = "helloworld"

result = {}

for keys in my_string:
result[keys] = result.get(keys, 0) + 1

print(result)``````

Output

``{'h': 1, 'e': 1, 'l': 3, 'o': 2, 'w': 1, 'r': 1, 'd': 1}``
