例如

line = inf.readline()
while (userType == raw_input)
print "userType\n"
if (userType == "")
print "invalid entry, the program will terminate"
# some code to close the app
推荐答案
我知道这很旧,但是将来可能会对某人有所帮助.我想出了如何用正则表达式来做到这一点.这是我的代码:
I know this is old, but this may help someone in the future. I figured out how to do this with regex. Here is my code:
import re
command = raw_input("Enter command :")
if re.search(r'[\s]', command):
print "No spaces please."
else:
print "Do your thing!"
