我正在尝试制作一个简单的工具,用于将英寸转换为厘米,但现在卡在了如何接受用户输入(“y”或“n”)以决定是否进行另一次转换或终止程序上。这是我的代码:
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()
结果如下:
追溯(最近的调用): 文件“C:\Users\Sam\Programming\Python\the hard way\ex5.4.py”,第29行, intro() 文件“C:\Users\Sam\Programming\Python\the hard way\ex5.4.py”,第5行, intro() 文件“C:\Users\Sam\Programming\Python\the hard way\ex5.4.py”,第12行, restart = str(input("您是否希望进行另一次转换?[y]是或[n]否?\n")) 文件“”,第1行, NameError: name 'y' is not defined
需要帮助请告知。
raw_input
而不是input
