I however would like to add in another line that tells the user their account

OK, Time to introdusce another Pyhon idioM, the break clause.
while True: # loop forever
get input from user
check/convert input
if no errors:
break # exits the loop
print error message here
"Please Input Your Account Number:")
userAccountNumber = int(userAccount)
As for users typing in a name like "Charlie" or a float I would like that to
spit out
an error also, but I haven't learned how to accomplish that yet.
The code you have will detect the error and throw an exception.
To stay in the loop you need to catch those exceptions in a try/except
clause.
while True:
try:
get input
check/convert input
break
except error1, error2,....:
print error messages here
If you haven't covered try/except yet then you should read up on it
as it has several variations and subtleties.
