One suggestion to build a satisfactory password is to start with a memorable phrase or sentence and make a password by extracting the first letter of each word. 

Even better is to replace some of those letters with numbers (e.g., the letter `O` can be replaced with the number `0`):

* instead of including `i` or `I` put the number `1` in the password;
* instead of including `o` or `O` put the number `0` in the password;
* instead of including `s` or `S` put the number `5` in the password.


## Examples:
```
"Give me liberty or give me death"  --> "Gml0gmd"
"Keep Calm and Carry On"            --> "KCaC0"
```

Solutions:
SWAP = {'i': '1', 'I': '1', 'o': '0', 'O': '0', 's': '5', 'S': '5'}

    phrase = phrase.split(" ")
    for i in phrase:
        new += i[0]
    return new

def make_password(phrase, mapping=dict(['i1', 'o0', 's5'])):
    return ''.join(mapping.get(c.lower(), c) for c, *rest in phrase.split())

    return ''.join(w[0] for w in s.split()).translate(TABLE)

    phrase = phrase.split(" ")
    password = ""
    for word in phrase:
