It next validates the slot number, if not within valid range, prints "Invalid slot number". If user enters non-integer input, prints "Please enter integer" using try/except code block. If valid, prompts the user for the new name and new number and updates entries in the two global lists for the slot number. It then prints "Updated slot number X" where X is the slot number user entered. dialByName: Function to handle dial by name command which prompts the user for the name. It then checks if the name is present in dialerNames list. (Make the name comparison case-insensitive). If not present, prints "Name not found."

The 3 functions listed below and make sure the program runs as shown in the sample runs. Note that the functions are expected to work on the global lists, no need to pass them as arguments.
dialBySlot: Function to handle dial by slot number command which prompts the user for the slot number and validates the slot number. If not within valid range (1 through 5), prints "Invalid slot number". If user enters non-integer input, prints "Please enter integer" using try/except code block. Otherwise checks if the slot at the given slot number is empty, if so prints "Slot empty" else prints "Calling name ........xxx-xxx-xxxx"
E.g. If user enters 3 and slot number 3 (values at index 2 in above lists) had name = "Susan" and number 4255551212, this function will print "Dialing Susan .......425-555-1212".
updateBySlot: Function to handle update by slot number command which prompts the user for the slot number to be updated. It next validates the slot number, if not within valid range, prints "Invalid slot number". If user enters non-integer input, prints "Please enter integer" using try/except code block. If valid, prompts the user for the new name and new number and updates entries in the two global lists for the slot number. It then prints "Updated slot number X" where X is the slot number user entered.
dialByName: Function to handle dial by name command which prompts the user for the name. It then checks if the name is present in dialerNames list. (Make the name comparison case-insensitive). If not present, prints "Name not found." If present, prints "Calling name ....xxx-xxx-xxxx"
E.g. If user enters "Susan" and slot number 3 (values at index 2 in above lists) had name = "Susan" and number 4255551212, dialByName() will print
