Python:名称错误名称“[输入]”未定义[重复]

问题描述 投票:0回答:1

我正在尝试制作一个简单的小工具,用于将英寸转换为厘米,并且一直试图获取用户输入(“y”或“n”)来决定是否进行另一次转换或终止。这是我所做的:

import time

def intro():
    print "Welcome! This program will convert inches to centimeters for you.\n"
    convert()

def convert():
    input_cm = input(("Inches: "))
    inches_conv = input_cm * 2.54
    print "Centimeters: %f\n" % inches_conv
    time.sleep(3)
    restart = str(input("Do you wish to make another conversion? [y]Yes or [n]no: "))
    if restart == 'y':
        convert()
    elif restart == 'n':
        end_fast()
    else:
        print "I didn't quite understand that answer. Terminating."
        end_slow()

def end_fast():
    print "This program will close in 5 seconds."
    time.sleep(5)

def end_slow():
    print "This program will close in 30 seconds."
    time.sleep(30)

intro()

这会导致:

回溯(最近一次调用最后一次): 文件“C:\Users\Sam\Programming\Python he Hard way x5.4.py”,第 29 行,位于 介绍() 文件“C:\Users\Sam\Programming\Python he Hard way x5.4.py”,第 5 行,简介 转变() 文件“C:\Users\Sam\Programming\Python he Hard way x5.4.py”,第 12 行,在转换中 restart = str(input("您希望进行另一次转换吗?[y]是还是[n]否? ”)) 文件“”,第 1 行,位于 名称错误:名称“y”未定义

感谢帮助。

而不是

input
尝试
raw_input

替换:

restart = str(input("Do you wish to make another conversion? [y]Yes or [n]no: "))

上:

restart = raw_input("Do you wish to make another conversion? [y]Yes or [n]no: ")
