我想将此文件拆分为4个不同的文件。只要中间有空行，就应将它分开。我是python的新手。任何帮助将不胜感激。

Answer 1

问题很简单。你可以拥有一个不断迭代文件中每一行的计数器。

i = 0
for line in open("somefile", "r"):
    if len(line.strip()) == 0:
        continue
    with open("new_file{}".format(i), "w") as new_file:
        new_file.write(line)
    i += 1

如果你想使用该语言的一些更高级的功能，你可以放弃使用的LOC并摆脱丑陋的if / else语句

lines = open("somefile", "r").readlines()
non_empty = [line for line in lines if len(line.strip()) != 0]
for i, line in enumerate(non_empty):
    with open("new file{}".format(i), "w") as new_file:
        new_file.write(line)

Answer 2

您可以使用re立即拆分：

import re
for x in re.split('\n\n',open('bla.txt').read()):
    open(x.split("\n")[0].strip('()').replace(" ","_"),'w').write(x)

x.split部分是根据标题确定文件名，您可以更改它。
