Python uppercase the entire string except letters which are within quotes but after colon-CodePudding

I have string in python like

INS_hdr:"To:abc.micky.com|From:xyz.micky.com",TRANSFERTARGET:"B_london"

need to convert to like this

INS_HDR:"TO:abc.micky.com|FROM:xyz.micky.com",TRANSFERTARGET:"B_LONDON"

I dont want to convert string to uppercase based on colon, as i use multiple colon in string, need to convert uppercase based on colon which appear inside quotes

CodePudding user response：

I would just brute force it, iterating and keeping track of the state (in quote, in quote after colon, not in quote).

CodePudding user response：

Given your particular example, you could re.split on : with a non quoted word, then loop over the groups to determine which ones to make upper case based on the leading colon:

import re

s = 'INS_hdr:"To:abc.micky.com|From:xyz.micky.com",TRANSFERTARGET:"B_london"'

''.join(x.upper() if not x.startswith(':') else x 
        for x in re.split('(:[^"|] )', s))

output:

INS_HDR:"TO:abc.micky.com|FROM:xyz.micky.com",TRANSFERTARGET:"B_LONDON"
