[英]Partitioning multiline string in python
I'm running a unix command using python script, I'm storing its output (multi-line) in a string variable. 我正在使用python脚本运行unix命令,并将其输出(多行)存储在字符串变量中。 Now I have to make 3 files using that multi-line string by partitioning it into three parts (Delimited by a pattern End---End ). 现在,我必须使用该多行字符串将其分为三个部分(由模式End --- End分隔)来制作3个文件。
This is what my Output variable contains 这是我的输出变量包含的内容
Output = """Text for file_A
something related to file_A
End---End
Text for file_B
something related to file_B
End---End
Text for file_C
something related to file_C
End---End"""
Now I want to have three files file_A, file_B and file_C for this value of Output:- 现在,我想使用三个文件file_A,file_B和file_C作为此Output值:
contents of file_A file_A的内容
Text for file_A
something related to file_A
contents of file_B file_B的内容
Text for file_B
something related to file_B
contents of file_C file_C的内容
Text for file_C
something related to file_C
Also if Output doesn't have any text for its respective file then I don't want that file to be created. 另外,如果Output的相应文件没有任何文本,则我不希望创建该文件。
Eg 例如
Output = """End---End
Text for file_B
something related to file_B
End---End
Text for file_C
something related to file_C
End---End"""
Now I only want file_B and file_C to be created as there is no text for file_A 现在我只希望创建file_B和file_C,因为没有file_A的文本
contents of file_B file_B的内容
Text for file_B
something related to file_B
contents of file_C file_C的内容
Text for file_C
something related to file_C
How can implement this in python? 如何在python中实现呢? Is there any module to partition a multi-line string using some delimeter? 是否有任何模块可以使用一些定界符对多行字符串进行分区?
Thanks :) 谢谢 :)
You can use the split()
method: 您可以使用split()
方法:
>>> pprint(Output.split('End---End'))
['Text for file_A\nsomething related to file_A\n',
'\nText for file_B\nsomething related to file_B\n',
'\nText for file_C\nsomething related to file_C\n',
'']
Since there is a 'End---End'
at the end, the last split returns ''
, so you can specify the number of splits: 由于'End---End'
有一个'End---End'
,最后一个分割返回''
,因此您可以指定分割数:
>>> pprint(Output.split('End---End',2))
['Text for file_A\nsomething related to file_A\n',
'\nText for file_B\nsomething related to file_B\n',
'\nText for file_C\nsomething related to file_C\nEnd---End']
Output = """Text for file_A
something related to file_A
End---End
Text for file_B
something related to file_B
End---End
Text for file_C
something related to file_C
End---End"""
ofiles = ('file_A', 'file_B', 'file_C')
def write_files(files, output):
for f, contents in zip(files, output.split('End---End')):
if contents:
with open(f,'w') as fh:
fh.write(contents)
write_files(ofiles, Output)
