python remove characters between quotes

Question

I tried to remove characters between quotes.

Input string: "a string ,5,to",5,6,my,use,"123456,inside",1,a,b

I would like this output: 5,6,my,use,1,a,b

I tried with re.sub without success:

line = ['"a string ,5,to",5,6,my,use,"123456,inside",1,a,b']
substr = re.sub("["].*?["]", "", line)

many thanks for any help

Answer 1

You can match two double-quotes with zero or more non-double-quote characters in between, and substitute the match with an empty string. Also match an optional comma that follows to remove it:

import re

line = '"a string ,5,to",5,6,my,use,"123456,inside",1,a,b'
print(re.sub(r'"[^"]*",?', '', line))

This outputs:

5,6,my,use,1,a,b

Answer 2

maybe try this:

import re

input_string = '"a string ,5,to",5,6,my,use,"123456,inside",1,a,b'
output_list = re.findall(r'"[^"]*?"|w+', input_string)
output_string = ','.join([word for word in output_list if not 
word.startswith('"')])

print(output_string)

my output:

5,6,my,use,1,a,b
