Hack for unix/perl style find and replace in Python

perl.py

import inspect

class Find(object):
    def __div__(self, find_term):
        frame = inspect.stack()[0][0].f_back

        line = inspect.getframeinfo(frame)[3][0]
        
        equal_index = line.index("=")
        variable_name = line[:equal_index - 1].strip()
        return Replace(frame.f_locals[variable_name], find_term)

class Replace(object):
    def __init__(self, string, find_term):
        self.string = string
        self.find_term = find_term

    def __div__(self, replace):
        return self.string.replace(self.find_term, replace)

s = Find()

test_string = "This is a test string"

test_string = s/"string"/"potato"

print(test_string)
