Why does code fail to replace space with underscore

Question

Hi please can someone explain why the underscore in this code fails to show when printed. Thank you.

names = ["Joey Tribbiani", "Monica Geller", "Chandler Bing", "Phoebe Buffay"]
usernames = []
for name in names:
    name.lower().replace(" ", "_")
    usernames.append(name)

print(usernames)

Output

['Joey Tribbiani', 'Monica Geller', 'Chandler Bing', 'Phoebe Buffay']

It does. It just doesn't do anything to the *list*. – jonrsharpe Sep 06 '20 at 15:19 — jonrsharpe, Sep 06 '20 at 15:19

It was because you were not assigning the processed data to variable name.

names = ["Joey Tribbiani", "Monica Geller", "Chandler Bing", "Phoebe Buffay"]
usernames = []
for name in names:
    name=name.lower().replace(" ", "_")
    usernames.append(name)

print(usernames)
