replacing a string with a character

Question

Hi Everyone,
Does anyone know how to change a string to a character? for example, If I wanted to check if a specific word was in a paragraph and if it was, change that word to the same length, but 'X's.
If that word I was changing was 'algorithms', the output would be XXXXXXXXXXX.

I know I have to check each character of the word and if it's not an X, replace it, but I'm a bit stuck on how to do so.
Appreciate any help.
Thanks!

You should be careful using a character based replacement. by using the input shown down here, the result will be: >>> "take this flower XXX keep it with your hXXXs". the replacement has also modified a part of a word.

sentence = 'take this flower and keep it in your hands'
to_replace = 'and'
replacement = 'X'

word_lst = sentence.split()

res = [word if word != to_replace else replacement * len(word) for word in word_lst]
print(' '.join(res))

result will be: >>> "take this flower XXX keep it in your hands"

It would be better if you showed your attempt 🙃

But anyways, you can refer to this code!
