python try/exception help -

i'm trying support repetition user inputs filename, inputs 2 integers. if exception thrown, want user prompted input again.

my problem if valid file entered invalid integer entered ask file again instead of integer. how can fix code ask integer again.

here have:

while true:     try:         f = raw_input("enter name of file: ")         infile = open(f)         # more code     except ioerror:         print ("the file not exist. try again.")             else:             try:             integer = int(raw_input("enter integer: "))             integer2 = int(raw_input("enter integer: "))             # more code         except (typeerror, valueerror):             print ("not integer. try again.") 

try use multiple while loops:

while true:     filename = raw_input("enter name of file: ")     try:         # more code here detect or open file         break     except exception:  # can ioerror or else         print ("error msg")  while true:     try:         integer = int(raw_input("enter integer: "))         integer2 = int(raw_input("enter integer: "))         break     except (typeerror, valueerror):         print ("error msg")  # more code
