# Python – Words Frequency in String Shorthand’s

Sometimes while working with Python strings, we can have problem in which we need to extract frequency of all the words in string. This problem has been solved earlier. This discusses the shorthands to solve this problem as this has application in many domains ranging from web development and competitive programming. Let’s discuss certain ways in which this problem can be solved.

Input : test_str = ‘Gfg is best’
Output : {‘Gfg’: 1, ‘is’: 1, ‘best’: 1}

Input : test_str = ‘Gfg Gfg Gfg’
Output : {‘Gfg’: 3}

Method #1 : Using dictionary comprehension + `count() + split()`
The combination of above functions can be used to solve this problem. In this, we first split all the words and then perform count of them using count(). Python3 code to demonstrate working of Words Frequency in String Shorthands Using dictionary comprehension + count() + split() initializing string test_str = ‘Gfg is best . Geeks are good and Geeks like Gfg’ printing original string print(“The original string is : ” + str(test_str)) Words Frequency in String Shorthands Using dictionary comprehension + count() + split() res = {key: test_str.count(key) for key in test_str.split()} printing result print(“The words frequency : ” + str(res))

Output :

The original string is : Gfg is best . Geeks are good and Geeks like Gfg
The words frequency : {‘Gfg’: 2, ‘is’: 1, ‘best’: 1, ‘.’: 1, ‘Geeks’: 2, ‘are’: 1, ‘good’: 1, ‘and’: 1, ‘like’: 1}

Method #2 : Using `Counter() + split()`
The combination of above methods can also be used to solve this problem. In this, we perform the task of counting using Counter() and separation of words using split().Python3 code to demonstrate working of Words Frequency in String Shorthands Using Counter() + split() from collections import Counter initializing strin test_str = ‘Gfg is best . Geeks are good and Geeks like Gfg’ printing original string print(“The original string is : ” + str(test_str)) Words Frequency in String Shorthands Using Counter() + split() res = Counter(test_str.split()) printing result print(“The words frequency : ” + str(dict(res)))

Output :

The original string is : Gfg is best . Geeks are good and Geeks like Gfg
The words frequency : {‘Gfg’: 2, ‘is’: 1, ‘best’: 1, ‘.’: 1, ‘Geeks’: 2, ‘are’: 1, ‘good’: 1, ‘and’: 1, ‘like’: 1}
