What do you mean with save itself? But in case you want a global variable, just do: global user_name user_name = input()

You can write two functions, each of them returning a single value. Or Python also allows to return several values as a tuple. Then you also need to destructure the result into multiple variables, or use indices. def multi_return(): return ('hello', 42) first, second = multi_return() Declaring global variables is bad practice, avoid if possible.

# Hi Bogyo - Leția Eduard # When you assign a value to a variable in the modul layer, it become global. # So if return a value from a function, and assign the returned value in a variable, it will of course be global. But if you want to assign a value to a global vaiable from inside the function, you have to use the keyword ’global’: >> def f(x): >> global y >> y = 2 * x >> >> f(10) # Creates the global variable y. >> print(y) # Print the global variable y. 20
