I have some python code that splits on comma, but doesn't strip the whitespace:
>>> string = "blah, lots , of , spaces, here " >>> mylist = string.split(',') >>> print mylist ['blah', ' lots ', ' of ', ' spaces', ' here '] I would rather end up with whitespace removed like this:
['blah', 'lots', 'of', 'spaces', 'here'] I am aware that I could loop through the list and strip() each item but, as this is Python, I'm guessing there's a quicker, easier and more elegant way of doing it.

The + operator, also known as the string concatenation operator, can be used in this case to prevent unnecessary spacing between the values. It's a direct alternative to comma separation and can be used along with the print statement.
To split a string by space or comma, pass the following regular expression to the split() method - /[, ]+/ . The method will split the string on each occurrence of a space or comma and return an array containing the substrings.
The split() method splits a string into a list. You can specify the separator, default separator is any whitespace. Note: When maxsplit is specified, the list will contain the specified number of elements plus one.
You can use the Python string split() function to split a string (by a delimiter) into a list of strings. To split a string by comma in Python, pass the comma character "," as a delimiter to the split() function. It returns a list of strings resulting from splitting the original string on the occurrences of "," .
Use list comprehension -- simpler, and just as easy to read as a for loop.
my_string = "blah, lots , of , spaces, here " result = [x.strip() for x in my_string.split(',')] # result is ["blah", "lots", "of", "spaces", "here"] See: Python docs on List Comprehension
A good 2 second explanation of list comprehension.
