Which approach should I take?

Question

If I want to replace a word in a sentenance with another word. So should I take the approach of a for loop for that or .sub() method?

Answer 1

I would use:

string = string.replace("word1", "word2")

Answer 2

Thanks. I never knew about this method.

Answer 3

I think the .sub() method is better due to its easy and short syntax. But at first it is confusing.
