Sorry if this post is a bit confusing to read this is my first post on this site and this is a hard question to ask, I have tried my best. I have also tried googling and i can not find anything. I am trying to make my own command line like application in python and i would like to know how to split a string if a "\" is not in front of a space and to delete the backslash. This is what i mean. >>> c = "play song I\ Want\ To\ Break\ Free" >>> print c.split(" ") ['play', 'song', 'I\\', 'Want\\', 'To\\', 'Break\\', 'Free'] When I split c with a space it keeps the backslash however it removes the space. This is how I want it to be like: >>> c = "play song I\ Want\ To\ Break\ Free" >>> print c.split(" ") ['play', 'song', 'I ', 'Want ', 'To ', 'Break ', 'Free'] If someone can help me that would be great! Also if it needs Regular expressions could you please explain it more because I have never used them before. Edit: Now this has been solved i forgot to ask is there a way on how to detect if the backslash has been escaped or not too? Continue reading...
