I'm trying to make a simple little tool for converting inches to centimeters and am stuck at trying to take a user input ('y' or 'n') for deciding whether to do another conversion or terminate. Here's what I've done:
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()
结果是:

推荐答案
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: ")
