Question

我是一个非常初期的程序员，正在寻找一些可能是一个非常简单的问题的帮助。我正在尝试编写一个程序来读取.txt文件，然后用'xxxxx'替换任何带有'e'的单词。

这是我到目前为止所做的：

def replace_ewords(text):
    ntext = text.replace('e', 'xxxxx')

def main():
    filename = "gb.txt"
    text = readfile(filename)
    new_text = replace_ewords(text)
    print(new_text)

main()

有人可以帮我解决这个问题吗？

Answer 1

def replace_ewords(text):
    words = []
    text = text.split(' ')
    for word in text:
        if "e" in text:
            words.append("x"*len(text))
        else:
            words.append(text)
    return " ".join(words)

Answer 2

with open('filename') as f:   # Better way to open files :)
    line_list = []
    for line in file:   # iterate line by line
        word_list = []
        for word in line.split()   # split each line into words
            if 'e' in word:
                word = 'xxxxx'     # replace content if word has 'e'
            word_list.append(word) # create new list for the word content in new file
        line_list.append(' '.join(word_list))   # list of modified line

# write this content to the file

循环的一行可以以列表解析的形式写成：

 [' '.join([('xxxx' if 'e' in word else word) for word in line]) for line in file.readlines()]

Answer 3

一个班轮：

print "\n".join([" ".join([[word, "xxx"]["e" in word] for word in line.split()]) for line in open("file").readlines()])
