String comparison in python not working inside the function

can someone explain me why the equality operator is not working inside this function?

def count_words(words_to_insert, word):

    counter = 0
    
    for i in range(0,words_to_insert):
        random_word = input("Insert a string ")
        
        print(random_word)
        print(random_word == word)
        
        if(random_word == word):
            counter +=1
            print(counter)
    
    return "You inserted the word " + word + " " + str(counter) + " times"

count_words(2, "mango")

If I write two strings outside the function with the same values and I compare them, the result is True

string_one = "mango"
string_two = "mango"
string_one == string_two

OUT

True

>Solution :

Do not type " when inputting:

>>> Insert a string "mango"
>>> "mango"
>>> False

>>> Insert a string mango
>>> mango
>>> True
