Higher or lower python program keeps printing 'builtin_function_or_method' is not iterable?

That's the program and I mport random is there
...................................
starting number is 12
Is the next number Higher (H) or Lower (L)? L
next number 16
starting number is 20
Is the next number Higher (H) or Lower (L)? H
next number 1

that's the out put, whats gone wrong in the second part?

or:lives = 2wins= 0#the list of numbers to randomly pick fromsequence= [1, 2, 3 ,4 ,5 , 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 ]nextno= random.choice(sequence)print(\"starting number is\

or:Haven't read the whole code (it looks terrible), but the error is in line 34.user = user.upper means you define user to be the FUNCTION uppercase. Adding brackets () at the end activates the function as intended.Get an IDE so you can debug the code and actually see where the user changes to the non-iterable type.
