删除python中文本文件的特定模式

Question

我有一个名为file1的输入文件，其中包含：

Student 0 : Performed well but can do better. [76.50%]

Student 1 : Brilliant performance. [98.50%]

在这个特定的文件中，我只想删除%部分，以便它生成如下输出：

Student 0 : Performed well but can do better.

Student 1 : Brilliant performance.

我试着这样做：

with open('file1', 'r') as infile, open('file2', 'w') as outfile:
    temp = infile.read().replace("[[0-9]+]", "").replace("%","")
    outfile.write(temp)

但这只是删除%符号并将输出作为：

Student 0 : Performed well but can do better. [76.50]

Student 1 : Brilliant performance. [98.50]

Answer 1

您仍然需要正则表达式：

import re
with open('file1', 'r') as infile, open('file2', 'w') as outfile:
    temp = re.sub("\[[\d+\.%]+\]", "", infile.read())
    outfile.write(temp)
