how do I replace a string in a phrase in python?

so this is the code i made in pyhton and for some reason it does not work so i hoped that someone here could help me find a solution * i am just a begginer *

    def replace(phrase):
    replaced = ""
    for word in phrase:
        if word == ("what"):
            replaced = replaced + "the"
        else:
            replaced = replaced + word
    return replaced

    print(replace(input("enter a phrase: ")))

You can try this code, I hope it helps you

def replace(phrase):
    phrase = phrase.split()
    replaced = ""
    for word in phrase:
        if word == ("what"):
            replaced = replaced + " the"
        else:
            replaced = replaced +" "+ word
    return replaced[1:]

print(replace(input("enter a phrase: ")))

The output is:

enter a phrase: where what this what when ,
where the this the when ,

Here we use .split() to split your phrase by the space. As a result you get a list of each word ['hi', 'what', 'world']. If you don't split it, you will loop through each character if the string instead and no character will ever equal "what"

 def replace(phrase):
    phrase = phrase.split()
    replaced = ""
    for word in phrase:
        if word == ("what"):
            replaced = replaced + " the "
        else:
            replaced = replaced + word
    return replaced

print(replace(input("enter a phrase: ")))

Try the replace method instead:

def replace(phrase):
  replaced = phrase.replace("what","the")
  return replaced
