# solution to accept a 9-digit integer representing an unformatted student identification number 

#Solution outputs formatted student identification number as a string 



# this practice gives you a way to show you how to put in the first digit in the code 

print("Enter Student Identification Number:")
phone_number = int(input())

first_digit = phone_number // 10 ** 9
area_code = (phone_number // 10 ** 6) % 1000
prefix  = (phone_number // 10 ** 3) % 1000
line_number = phone_number % 1000

print(f"+{first_digit} - {area_code} - {prefix} - {line_number}")


# this is without the first digit to put in the code 

print("Enter Student Identification Number:")
phone_number = int(input())

area_code = (phone_number // 10 ** 6) % 1000
prefix = (phone_number // 10 ** 4) % 100 
line_number phone_number % 10000

print(f"{area_code}-{prefix}-{line_number}")

# The more zeros the more it will duplicate the numbers from the their place holder
