How to remove characters from Python list?

Question

I have a LIST: ['tag1', 'tag2', 'tag3 tag3', ...]

How do I delete [, ], '. I want to get a string: "tag1, tag2, tag3 tag3, ..."

Answer 1

One simple way, for your example, would be to take the substring that excludes the first and last character.

myStr = myStr[1:-1]

Answer 2

> import re
>>> s = "[test, test2]"
>>> s = re.sub("\[|\]", "", s)
>>> s
'test, test2'

Answer 3

If the '[' and ']' will always be at the front and end of the string, you can use the string strip function.

s = '[tag1, tag2, tag3]'
s.strip('[]')

This should remove the brackets.

Answer 4

if you have a list of strings you could do:

>>> lst = ['tag1', 'tag2', 'tag3 tag3']
>>> ', '.join(lst)
'tag1, tag2, tag3 tag3'

Note: you do not remove characters [, ], '. You're concatenating elements of a list into a string. Original list will remain untouched. These characters serve for representing relevant types in python: lists and string, specifically.
