循环定义的代码时，“str”对象不可调用

Question

我有这个我正在尝试执行的脚本，但是当我尝试循环定义的代码时收到错误消息。我只有恢复的，因为它会在这里很长。另外，我需要帮助来放置我所有的变量并能够使用记事本访问它，因为我使用的是 python 的空闲版本，所以这会很有帮助！def recovered():    print("Recovered")    print("China =",China_3)      print("India",India_3)    print("USA =",USA_3)      print("Indonesia =",Indonesia_3)     print("Brazil =",Brazil_3)      print("Pakistan =",Pakistan_3)       print("Nigeria =",Nigeria_3)      print("Bangladesh =",Bangladesh_3)      print("Russia =",Russia_3)     print("Japan =",Japan_3)       print("Mexico =",Mexico_3)       print("Philippiness =",Philippines_)      print("Vietnam =",Vietnam_3)      print("Egypt =",Egypt_3)      print("Germany =",Germany_3)      print("Iran =",Iran_3)      print("Turkey =",Turkey_3)      print("Thiland =",Thailand_3)      print("France =",France_3)     print("United Kingdom =",United_Kingdom_3)     print("Italy =",Italy_3)     print("South Africa =",South_Africa_3)      print("South Korea =",South_Korea_3)     print("Columbia =",Colombia_3)      print("Spain =",Spain_3)     print("Ukraine =",Ukraine_3)      print("Kenya =",Kenya_3)       print("Argentina =",Argentina_3)      print("Poland =",Poland_3)      print("Sudan =",Sudan_3)      print("Uganda =",Uganda_3)      print("Canada =",Canada_3)      print("Now you are done with the tutorial, you will be able to explore your virus!")    print("")    print("""    Here are the controls:    1 = Cases    2 = Deaths    3 = Recovered    4 = DNA points    """)def main():    global DNA     global Smartness    global cases    global deaths    global recovered    print("Do your actions: ")    main = input("")  if main == "1":      cases()      print("")      main()  elif main == "2":      deaths()      print("")      main()  elif main == "3":      recovered()      print("")      main()  elif main == "4":      DNA()      print("")      main()  elif main == "5":      Smartness()      print("")      main()  else:      print("Only chose a number between 1 and 5!")      main()  main()
