Python: Iterating through string with a for loop returns two lines when printing

I have written this little program to change camelCase function descriptions into snake_case descriptions.

def main():
    #Get input and pass it to function
    string = input("Camelcase: ")
    make_snake(string)

def make_snake(string):
    for char in string:
        if char.isupper():
            string = string.replace(char, "_"+ (char))
            string_new = string.lower()
            print(f"snake_case: {string_new}")

main()

It works fine with camelCase words with one capital letter like firstName, but when I run it with camelCases with two capital letters like "preferredFirstName" print returns two lines:

preferred_firstname preferred_first_name

I want it to return only the second line. Any idea why that is? Thank you so much for your time! Michael

You need to wait till all letters have processed to print the converted string.

>>> def make_snake(string):
...     for char in string:
...         if char.isupper():
...             string = string.replace(char, "_"+ (char))
...     string_new = string.lower()
...     print("snake_case: "+string_new)
...
>>> make_snake('preferredFirstName')
snake_case: preferred_first_name
>>>
