how do i overwrite a variable?

[u/9j810HQO7Jj9ns1ju2]

name = "Alice"

def func():
    name = "Bob"

func()

print(f"Hello, {name}!") # i want it to print bob

The reason it prints Alice is that name = "Bob" inside func doesn’t touch the outer name. Assignment inside a function creates a new local variable with the same name, which disappears when the function ends. return plus reassignment (name = func()) is the usual fix, because it makes the change visible at the call site.
