python - How can i parse a comma delimited string into a list (caveat)?

Question

I need to be able to take a string like:

'''foo, bar, "one, two", three four'''

into:

['foo', 'bar', 'one, two', 'three four']

I have an feeling (with hints from #python) that the solution is going to involve the shlex module.

Answer 1

It depends how complicated you want to get... do you want to allow more than one type of quoting. How about escaped quotes?

Your syntax looks very much like the common CSV file format, which is supported by the Python standard library:

import csv
reader = csv.reader(['''foo, bar, "one, two", three four'''], skipinitialspace=True)
for r in reader:
  print r

Outputs:

['foo', 'bar', 'one, two', 'three four']

HTH!
