Pycharm“完成，退出代码为0”

Question

def main():
countries = ("England", "Palestine", "Israel", "Uzbekistan", "DRC" )
print(countries)
choice = input("Please pick one of these countries: ")
if choice == "England":
    print(countries[0])
elif choice == "Palestine":
    print(countries[1])
elif choice == "Israel":
    print(countries[2])
elif choice == "Ubekistan":
    print(countries[3])
elif choice == "DRC":
    print(countries[4])
else:
    print("Please enter a country on the list!")
    main()
main()

[每当我在pycharm上运行此代码时，我都会收到“进程已完成，退出代码为0”。我使用“ Shift + F10”运行。

不确定在pycharm]中运行这段代码时，您的电脑到底出了什么问题，但我在线使用了以下内容，我注意到的一个主要问题是，经过适当的缩进后，您的缩进问题在代码中可以正常运行了关注在线python解释器，link

def main():
  countries = ("England", "Palestine", "Israel","Uzbekistan", "DRC")
  print(countries)
  choice = input("Please pick one of these countries: ")
  if choice == "England":
      print(countries[0])
  elif choice == "Palestine":
      print(countries[1])
  elif choice == "Israel":
      print(countries[2])
  elif choice == "Ubekistan":
      print(countries[3])
  elif choice == "DRC":
      print(countries[4])
  else:
      print("Please enter a country on the list!")
      main()
main()
为了以后的工作，最好在脚本的开头（写了main()的位置）添加以下内容：

if __name__=='__main':
    main()
