NameError: name 'user_input' is not defined

 

Niby błąd prosty ale nie mam zielonego pojęcie co tam zrobiłem źle.

A gdzie definiujesz user_input? Odwołujesz się jakby była globalnie zdefiniowana.

Answer 1

choice_0 = 'y'
choice_1 = 'n'

direction = ""
user_input = ""
menu_input = ""

action = "You woke up in the woods."

Po "poprawieniu" błędu, który opisał wyżej @PanPrezes, pojawił mi się kolejny, jak niżej:

Ten zapis nie działa w Windows10 x64 Python 3.8.3

def screen_clear():
   _ = call('clear' if os.name =='posix' else 'cls')

Zwraca taki bład:

ten działa:

def screen_clear():
    os.system('cls' if os.name=='nt' else 'clear')

lub

def screen_clear():
    _ = lambda: subprocess.call('cls||clear', shell=True)

mój ulubiony

# działa windows, linux, i nie tylko w python'ie :-)
screen_clear = lambda: print("\033[H\033[2J")

Na pewno nie pomyliłeś pytań? Bo coś nie mogę uwierzyć by tak zinterpretować błąd OPa
