Thanks.  Would this:


def newuser():
    new = raw_input("Are you a new user [y/n]? ")
    while new not in 'yYnN':
        new = raw_input("""
        Please enter 'y' for yes or 'n' for no.
        Are you a new user? """)
    if new in 'yY':
        import math
        vowelcount = 0
        global rannum = []
        name = raw_input("Please enter your first name. ")
        name = name[:6]
        namel = raw_input("Please enter your last name. ")
        namel = namel[:6]
        name = name + ' ' + namel
        vowels = ['a','e','i','o','u','A','E','I','O','U']
        for letter in name:
            if letter in vowels:
                vowelcount = vowelcount + 1
        global startmon
        for i in range(10):
            rannum.append.int(round(random.random() * 1000000))
        startmon = vowelcount * rannum[0]
        startmon = str(startmon)[:7]
        startmon = int(float(startmon))
        print "Welcome, %s.  You have $%d to use in BankSim 1.0." % (name,
startmon)
def newacc():
    global newac
    newac = raw_input("Would you like to create a new account [y/n]? ")
    while newac not in 'yYnN':
        newac = raw_input("""
        Please enter 'y' for yes or 'n' for no.
        Would you like to create a new acount [y/n]? """)
    if newac in 'yY':
        import math
        global newacid
        newacid = int(raw_input("Please enter your birthday [ddmmyyyy]. "))
        newacid = newacid * rannum[5]
        newacid = str(newacid)[:6]
        newacid = int(float(newacid))
        initbal = int(raw_input("How much money would you like to put in
your account? "))
        print "Account number %d created with $%d in it." % (newacid,
initbal)
        mon = startmon - initbal
        print "You now have $%d in account %d and $%d out of the bank." %
(initbal, newacid, mon)

work using your example? (The relevant portion is bolded).

Thanks again,

  Well, the random module is pretty easy to use.
  Here is a an example:

>>> import random
>>> l = []
>>> for i in range(10):
..  l.append(int(random.random()*10))
..
>>> l
[4, 2, 0, 3, 7, 8, 5, 9, 9, 8]
>>>

  random.random() gives a floating point number between 0 and 1, so I just
multiplied it by 10 to get from 0-10 then cast it to an integer with int().
  To get a more accurate representation (since int() truncates the argument)
you could use int(round(...)) instead.

  HTH,
  Glen
