我想知道如何在Python中重複一個過程？

Question

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，如果這個問題問你​​創建從word1 = raw input重複到repeat = raw_input(asking fort two more words)一個代碼，如果no == Good bye!

Answer 1

只要把所有的代碼在你的循環，其迭代只要repeat（初始化爲「y」等於「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)")

只是迭代器來迭代和重複該過程。欲瞭解更多信息，請參閱參考鏈接http://www.pythonlearn.com/html-008/cfbook006.html
