Question

我正在尝试从服务器重定向并根据切换结果显示网页，但我收到了下一个错误：

while True:
    message = input("q to quit\n"  # use implicit string joining
                    "w to walk randomly for 1000 steps\n"
                    "e to erase screen and walk randomly\n"
                    "> ")[:1].lower()  # forgive non-exact input
    if message == "q":
        print("Have a nice day!")
        break
    elif message =="w": 
        randomrun()
        jumpto(x,y)
    elif message == "e":
        t.clear()
        randomrun()
        jumpto(x,y)
    else:
        print("Input not recognized; try again.")

任何人都可以帮助我吗？提前致谢。 CGA
