Sample converter code I'm working on - unicode (or otherwise) symbols to plain English. Python 3.x

converter.py

def main():
    convert_table_example = {"$": "dollar",
                             "%": "percent",
                             "@": "at",
                             "alt": "alt",
                             ".": "period",
                             "\\": "backslash"
                             " ": "space",
                             ":": "colon"}
    # Convert the above as needed
    #get text.  This is quick and dirty, much more OOP-y in the real code
    cmd = input("Enter text to convert here: \n")
    #test input: cmd = 99.99%
    # test input: cmd = C:\Program Files
    
    # cmd may contain one, many, or none of the above dict entries.  All present must be replaced
    
    cmd.replace("$", "dollar")
    cmd.replace("%", "percent")
    cmd.replace("@", "at")
    #snip ...
    cmd.replace("\\", "backslash")
    
    #above only seems to evaluate the last one for some weird reason.  Weird glitch or should I try an alternate way?
    
    # regex magic goes here instead?
                             
    print("Your converted statement: " + cmd)
    
    #successful output: 99 period 99
    #successful output: C colon backslash Program space Files
