Python program to remove words that are common in two Strings
When it is required to remove words that are common in both the strings, a method is defined that takes two strings. The strings are spit based on spaces and list comprehension is used to filter out the result.
Example
Below is a demonstration of the same
def common_words_filter(my_string_1, my_string_2):
my_word_count = {}
for word in my_string_1.split():
my_word_count[word] = my_word_count.get(word, 0) + 1
for word in my_string_2.split():
my_word_count[word] = my_word_count.get(word, 0) + 1
return [word for word in my_word_count if my_word_count[word] == 1]
my_string_1 = "Python is fun"
print("The first string is :")
print(my_string_1)
my_string_2 = "Python is fun to learn"
print("The second string is :")
print(my_string_2)
print("The result is :")
print(common_words_filter(my_string_1, my_string_2))Output
The first string is : Python is fun The second string is : Python is fun to learn The uncommon words from the two strings are : ['to', 'learn']
Explanation
A method named ‘common_words_filter’ is defined that takes two strings as parameters.
An empty dictionary is defined,
The first string is split based on spaces and iterated over.
The ‘get’ method is used to get the word and the specific index.
The same is done for the second string.
The list comprehension is used to iterate through the dictionary and check if the word count is 1 or not.
Outside the method, two strings are defined and are displayed on the console.
The method is called by passing the required parameter.
The output is displayed on the console.
