Converting string to tuple without splitting characters

Question

I am striving to convert a string to a tuple without splitting the characters of the string in the process. Can somebody suggest an easy method to do this. Need a one liner.

Answer 1

I use this function to convert string to tuple

import ast

def parse_tuple(string):
    try:
        s = ast.literal_eval(str(string))
        if type(s) == tuple:
            return s
        return
    except:
        return

Usage

parse_tuple('("A","B","C",)')  # Result: ('A', 'B', 'C')

In your case, you do

value = parse_tuple("('%s',)" % a)
