Created November 5, 2013 09:30
A consultant once said, "Its hard to decide the username for new users. When using the first 3 letter from the firstname and surname. What about 'Bo Ek'". I figured how hard would that be, just repeat the last character . Like "boo, ekk". Turns out, in python, it was only 1 line.
def create_user_name(first_name, last_name, length=3):
"""The first 'length' (default 3) letters of first name and last name. Fills
out with last letter in the names if less than specified length. """
return first_name.ljust(length, first_name[-1])[:length] + \
last_name.ljust(length, last_name[-1])[:length]
# Examples
print create_user_name('bo', 'ek') # booekk
print create_user_name('niklas', 'forsstrom') # nikfor
print create_user_name('bo', 'ahl') # booahl

A couple of methods used for building a neat password. passwords is a generator of random passwords using a specfic set of characters and a min and max length. valid_password is just one validation, you can certainly make up more requirements for what should pass as a valid password. This one is used to specify how many digits, lowercase and upp…
