我试图写打开一个文本文件，并用*代替所有的四个字母的单词的程序。 我一直在瞎搞这个节目多小时。 我似乎无法取得任何进展。 我希望有人能帮助我这一个。 这里是我到目前为止所。 帮助是非常感谢！
def censor():
filename = input("Enter name of file: ")
file = open(filename, 'r')
file1 = open(filename, 'w')
for element in file:
words = element.split()
if len(words) == 4:
file1 = element.replace(words, "xxxx")
alist.append(bob)
print (file)
file.close()
这里修订verison，我不知道这是不是好多了
def censor():
filename = input("Enter name of file: ")
file = open(filename, 'r')
file1 = open(filename, 'w')
i = 0
for element in file:
words = element.split()
for i in range(len(words)):
if len(words[i]) == 4:
file1 = element.replace(i, "xxxx")
i = i+1
file.close()
for element in file:
words = element.split()
for word in words:
if len(word) == 4:
etc etc
这是因为：
说，在你的文件的第一行是“你好，我的名字是约翰”然后循环的第一次迭代： element = 'hello, my name is john'和words = ['hello,','my','name','is','john']
你需要检查什么是每个字里面从而for word in words
此外，它可能是值得一提的是，在当前的方法，你不支付任何注意标点符号。 请注意，在第一个字words上面...
为了摆脱标点符号的，而说：
import string
blah blah blah ...
for word in words:
cleaned_word = word.strip(string.punctuation)
if len(cleaned_word) == 4:
etc etc
这里是一个暗示： len(words)返回字的当前行数，而不是任何特定的字的长度。 您需要添加代码，想看看您的线路上的每一个字说，并决定是否需要更换。
此外，如果该文件是比文字的简单列表更复杂（例如，如果它包含了需要保留的标点字符），它可能会使用正则表达式来完成这项工作是值得的。
它可以是这样的：
def censor():
filename = input("Enter name of file: ")
with open(filename, 'r') as f:
lines = f.readlines()
newLines = []
for line in lines:
words = line.split()
for i, word in enumerate(words):
if len(word) == 4:
words[i] == '**'
newLines.append(' '.join(words))
with open(filename, 'w') as f:
for line in newLines:
f.write(line + '\n')
您需要更换字母w在w+第4行： file1 = open(filename, 'w')富人是file1 = open(filename, 'w+')我在这个项目上工作压力太大所以这是我的代码）
import os
import time
localtime = time.asctime( time.localtime(time.time()) )
a = input("What is your first name? ").title()
