How can I strip first and last double quotes?

Question

I want to strip double quotes from:

string = \'\"\" \" \" \"\"\\\\1\" \" \"\" \"\"\'

to obtain:

string = \'\" \" \" \"\"\\\         


        

Answer 1

Starting in Python 3.9, you can use removeprefix and removesuffix:

'"" " " ""\\1" " "" ""'.removeprefix('"').removesuffix('"')
# '" " " ""\\1" " "" "'

Answer 2

If you are sure there is a " at the beginning and at the end, which you want to remove, just do:

string = string[1:len(string)-1]

or

string = string[1:-1]

Answer 3

Below function will strip the empty spces and return the strings without quotes. If there are no quotes then it will return same string(stripped)

def removeQuote(str):
str = str.strip()
if re.search("^[\'\"].*[\'\"]$",str):
    str = str[1:-1]
    print("Removed Quotes",str)
else:
    print("Same String",str)
return str

Answer 4

Almost done. Quoting from http://docs.python.org/library/stdtypes.html?highlight=strip#str.strip

The chars argument is a string specifying the set of characters to be removed.

[...]

The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped:

So the argument is not a regexp.

>>> string = '"" " " ""\\1" " "" ""'
>>> string.strip('"')
' " " ""\\1" " "" '
>>> 

Note, that this is not exactly what you requested, because it eats multiple quotes from both end of the string!

Answer 5

I have some code that needs to strip single or double quotes, and I can't simply ast.literal_eval it.

if len(arg) > 1 and arg[0] in ('"\'') and arg[-1] == arg[0]:
    arg = arg[1:-1]

This is similar to ToolmakerSteve's answer, but it allows 0 length strings, and doesn't turn the single character " into an empty string.

Answer 6

Remove a determinated string from start and end from a string.

s = '""Hello World""'
s.strip('""')

> 'Hello World'
