我想知道如何在Python中重复一个过程？
问题描述：
print "You've entered a wording system!"
print "What words do you want?"
while False:
word1 = raw_input('enter your word:')
word2 = raw_input('enter your word:')
print word1
print word2
if len(word1)>len(word2):
word_difference = len(word1) - len(word2)
print word1, "is", word_difference, "letters longer than", word2
elif len(word2)>len(word1):
word_difference = len(word2) - len(word1)
print word2, "is", word_difference, "letters longer than", word1
elif len(word1) == len(word2):
print word1, "has same number of letters as", word2
repeat = raw_input("Would you like to enter two more words?(y/n)")
if repeat == "y":
y == False
，所以我想，如果这个问题问你创建从word1 = raw input重复到repeat = raw_input(asking fort two more words)一个代码，如果no == Good bye!我想知道如何在Python中重复一个过程？
答
只要把所有的代码在你的循环，其迭代只要repeat（初始化为“y”等于“y”）：
print "You've entered a wording system!"
print "What words do you want?"
repeat = "y"
while repeat == "y":
word1 = raw_input('enter your word:')
word2 = raw_input('enter your word:')
print word1
print word2
if len(word1)>len(word2):
word_difference = len(word1) - len(word2)
print word1, "is", word_difference, "letters longer than", word2
elif len(word2)>len(word1):
word_difference = len(word2) - len(word1)
print word2, "is", word_difference, "letters longer than", word1
elif len(word1) == len(word2):
print word1, "has same number of letters as", word2
repeat = raw_input("Would you like to enter two more words?(y/n)")
你已经告诉你如何编写一个while循环...为什么不使用另一个？ – James 2014-09-10 13:00:28
'while False'永远不会被执行，因为它是，呃，不是True。 – cdarke 2014-09-10 13:00:32
它看起来像所有的代码应该在第一个循环中，只要'repeat'等于“y”（在循环之前已经适当地初始化了'repeat'），它应该执行。 – chepner 2014-09-10 13:03:46
