Can two conditions be given for python's string.split function? [duplicate]

Python: Split string with multiple delimiters

I have a program where I am parsing a file by each line and splitting it into two half. After that for each half I am parsing each word from the line and appending it in a list.

Here mfcList1 is a list of lines from a text file. I am parsing each word in the line that are either separated by a comma or by a space. But it isn't exactly working.

for lines in mfcList1:
        lines = lines.lstrip()
        if lines!='':
            p.append(string.split(lines,','or " "))
mfcList2 = reduce(lambda x,y:x+y,p)

print mfcList2

When i am using string.split it is working with only those elements who end with a comma it is ignoring the or operator I am using with split method. I want to slice off each and everyword from the line. They either end with a comma or with a space.

for eg. 'enableEmergencySpare=1 useGlobalSparesForEmergency=1 useUnconfGoodForEmergency=1',

this line is being stored as a single list element where as I am trying to split them using split method..

Can anyone pls suggest what i can do instead of using or operator... thanks..

You can use split() from the re module:

import re
...
p.extend(re.split('[ ,]', lines))

The [ ,] is a regular expression which means "a space or a comma". Also, assuming p is a list and you want to add all the words to it, you should use extend() rather than append(), the latter adds a single element.

Note also that if a line in the file contains command followed by space (or other sequence of commas and spaces) your list p will contain a corresponding number of empty strings.

it didn't display the output in the list format. I want the output as a list..it just showed output as words separated by spaces but not a as a list.

Well, yes, because you combine all the elements of the list with reduce(). If you don't want to do it, then don't call reduce() and instead just display the list populated in the loop (i.e. p).

it is still printing the same thing. it is taking only , enableEmergencySpare=1 useGlobalSparesForEmergency=1 useUnconfGoodForEmergency=1
