  Yep.  Although, I'm not sure what you want to do with them, but that will
generate ten random numbers in your desired range.
  If you have any other questions, just send them along.

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
