字符串和整数输入 Python

Question

我需要它以便我可以输入整数和字符串值。这是因为我需要一个 'quit' 函数，它可以退出程序。

   movex = int(input("\nDesired X position, or quit >> "))
    if movey == "q" or movex == "q":
        break
    if movex < gsize and movex >= 0:
        #Do stuff
    movey = int(input("Desired Y position, or quit >> "))
    if movey < gsize and movey >= 0:
        #Do stuff

Answer 1

如果您使用的是 python，我认为根据您的语法，您可以执行以下操作：

import sys # if you want this what i said in later text...`
movex = raw_input("\nDesired X position, or quit >> ")
if movex == "q":
    break 
# don't really know what you want to do with this but i think you want to use sys.exit() to quit your porgram

movey = raw_input("\nDesired Y position, or quit >> ")
if movey == "q":
    break #same as in first...
try:
    movex_int = int(movex)
    movey_int = int(movey)
    if movex_int < gsize and movex_int >= 0:
          #Do stuff
    if movey_int < gsize and movey_int >= 0:
          #Do stuff

except ValueError: #if not an int the user didn't enter "q" but not either a number
    sys.exit() #this will exit program because parameters aren't expected, but you can do what you want

对于 python3 只需使用输入而不是 raw_input :)
