我有一个大文件，我想删除数据文件中的所有值'24'。我用过这个代码，但它不能满足我的要求。请提出建议。感谢
这是数据文件

代码
content = open('txt1.txt', 'r').readlines()
cleandata = []
for line in content:
line = {i:None for i in line.replace("n", "").split()}
for value in line.copy():
if value == "24":
line.pop(value)
cleandata.append(" ".join(line) + "n")
open('txt2.txt', 'w').writelines(cleandata)
这应该做到：
content = open('txt1.txt', 'r').readlines()
cleandata = []
for line in content:
line = line.replace('24','')
cleandata.append(line)
open('txt2.txt', 'w').writelines(cleandata)
您可以使用正则表达式来匹配24并删除它。
import re
regex24 = re.compile(r"b24,?b")
f = open('txt1.txt', 'r')
cleans = [regex24.sub("", line) for line in f.readlines()]
open('txt2.txt', 'w').writelines(cleans)
