If I want to split a list of words separated by a delimiter character, I can use
>>> 'abc,foo,bar'.split(',')
['abc', 'foo', 'bar']
But how to easily and quickly do the same thing if I also want to handle quoted-strings which can contain the delimiter character ?
In: 'abc,"a string, with a comma","another, one"'
Out: ['abc', 'a string, with a comma', 'another, one']
Related question: How can i parse a comma delimited string into a list (caveat)?

To convert a list to a string, use Python List Comprehension and the join() function. The list comprehension will traverse the elements one by one, and the join() method will concatenate the list's elements into a new string and return it as output.
To split a list into n parts in Python, use the numpy. array_split() function. The np. split() function splits the array into multiple sub-arrays.
import csv
input = ['abc,"a string, with a comma","another, one"']
parser = csv.reader(input)
for fields in parser:
for i,f in enumerate(fields):
print i,f # in Python 3 and up, print is a function; use: print(i,f)
Result:
0 abc 1 a string, with a comma 2 another, one
