Question

我的python程序有点麻烦。这是一个非常简单的程序，你可以输入命令，如＆＃34; stats＆＃34;它返回＆＃34;天气：＆＃34;，＆＃34;日：＆＃34;，＆＃34;温度：＆＃34;或者你可以输入命令＆＃34; day＆＃34;设定一天，＆＃34;天气＆＃34;设置天气，这样你就可以看到＆＃34; stats＆＃34;。在每个命令的末尾，＆＃34;命令输入＆＃34;应该再次出现。当您输入第一个命令时，命令会成功显示，并且＆＃34;命令输入＆＃34;再次出现（就像我想要的那样），但是当你再次输入另一个命令时，它会简单地打印出你刚输入的内容，命令不会执行而python编译器会关闭。

temp = "";
wea = "";
day = "";
input1 = input("What do you want: ");
if input1 == "stats":
    print ("Day: " + day)
    print ("Temperature: " + temp);
    print ("Weather: " + wea);
    input1 = input("What do you want: ");
elif input1 == "day":
    input2 = input("Set a day: ");
    day=input2;
    input1 = input("What do you want: ");
elif input1 == "weather":
    input3 = input("Set the weather: ");
    wea=input3;
    input1 = input("What do you want: ");
elif input1 == "temperature":
    input4 = input("Set the temperature: ");
    temp=input4;
    input1 = input("What do you want: ");
elif input1 == "commands":
    print ("Commands: ");
    print ("day");
    print ("weather");
    print ("temperature");
    input1 = input("What do you want: ");
else:
    print ("Unknow Command! Try the commmand \"commands\".");
    input1 = input("What do you want: ");

Answer 1

你的错误：

1）在Python中，您不需要使用;来结束语句。

2）使用while循环继续循环

3）while循环将退出，如果键入“quit”（您可以用您想要的任何其他内容替换“退出”）。

4）还有一个错字。

5）如果在循环中循环，你不需要多次写input()。

希望这会有所帮助：

temp = ""
wea = ""
day = ""
while True:
    input1 = input("What do you want: ","\n","Press (q) to quit.")
    if input1 == "stats":
        print("Day: " + day)
        print("Temperature: " + temp)
        print("Weather: " + wea)
    elif input1 == "day":
        input2 = input("Set a day: ")
        day = input2
    elif input1 == "weather":
        input3 = input("Set the weather: ")
        wea = input3
    elif input1 == "temperature":
        input4 = input("Set the temperature: ")
        temp = input4
    elif input1 == "commands":
        print("Commands: ")
        print("day")
        print("weather")
        print("temperature")
        print("quit')
    elif input1 == "quit":
        exit()
    else:
        print("Unknown Command! Try the commmand \"commands\".")

Answer 2

你似乎错过了一个循环。尝试以下方面：

temp = "";
wea = "";
day = "";
input1 = input("What do you want: ");
while not input1 == "exit":
  if input1 == "stats":
  ...
  ...

这应该会给你你想要的东西。有关循环的更多信息，请参阅here。
