如何使用findall在多个文件中分割文件

Question

我想在python中将文件分割成多个文件。因此，我找到了findall函数来完成这项工作。

我的文件包含：

**05/02/2020

- Test PC


- Electricite 
W=10
PUI=5



- Test MAPS
Nothing for now
- Date/Hours
DateTest=12h14
DateFinish=13h18

**05/02/2020

所以，我使用下面的代码用'-'分割该文件，但是分割得不是很好。

import re

def main():

  with open('mesfile.log', 'r') as f:
      data = f.read()

  found = re.findall(r'\n*(- .*?\- .*?)\n*', data, re.M | re.S)

  [open(str(i)+'.txt', 'w').write(found[i-1]) for i in range(1, len(found)+1)]

if __name__=="__main__":
  main()

预期输出

File 1 contains
- Test PC

File 2 contains
- Electricite 
W=10
PUI=5

File 3 contains
- Test MAPS
Nothing for now

 File 4 contains
- Date/Hours
DateTest=12h14
DateFinish=13h18

Answer 1

您可以尝试以下方法：

with open('mesfile.log', 'r') as f:
    data = [i.strip() for i in f]

contents = []
for line in data :
    if line.startswith('-') :
        contents.append([])
    contents[-1].append(line)

for i,text in enumerate(contents) :
    with open( 'file_%05d.txt' % i, 'w') as fout :
        fout.write( '\n'.join( text ) )

用途：

res = []
#read content
with open(filename) as infile:
    for line in infile:
        line = line.strip()
        if line.startswith("*") or not line:continue   #skip empty line or date lines
        if line.startswith("-"):
            res.append([line])
        else:
            res[-1].append(line)

#write data to file
for idx, data in enumerate(res):
    with open("file_{}".format(idx), "w") as infile:
        infile.writelines(data)
