I'm trying to rewrite the equivalent of the python replace() function without using regexp. Using this code, i've managed to get it to work with single chars, but not with more than one character:

def Replacer(self, find_char, replace_char):
    s = []
    for char in self.base_string:
        if char == find_char:
            char = replace_char
        #print char
        s.append(char)
    s = ''.join(s)

my_string.Replacer('a','E')

Anybody have any pointers how to make this work with more than one character? example:

my_string.Replacer('kl', 'lll')
