This assignment involves the use of a dictionary, functions, and Hexadecimal Binary 'O' Hexadecimal Binary "0000' '8' '1000' exception handling. '1' "0001' '9' '1001' Write a program that converts a number input in hexadecimal '2' '0010' 'A' '1010' into binary. The program should use a Python dictionary to hold the conversion pairs from hexadecimal to binary. For your reference, here is a table showing the conversions from hexadecimal to binary . '3' '0011' 'B' '1011' '4" '0100' 'C' '1100' '5' '0101' 'D' '1101' '6' '0110' 'E' '1110' '7' '0111' 'F' '1111' You should have two functions .. main() and convert(). The main() function should simply ask the user to enter a hexadecimal number, then pass the hex number to the convert() function. The convert() function should accept the hex number, then use the dictionary to determine the binary equivalent. The complete binary number should be returned to main(). The main() function should then print the binary number. Note that the hex number may have only one digit or it may have multiple digits. See the examples below. RESTART: C:\Users\dbatts00 Enter a hexadecimal number: B The binary equivalent is 1011 RESTART: C:\Users\dbattso0 Enter a hexadecimal number: 2A The binary equivalent is 00101010 >>> RESTART: C:\Users\dbatts0d Enter a hexadecimal number: B6F The binary equivalent is 101101101111 Make sure to check for a KeyError. (Remember that hexadecimal numbers must be 0 through F. Lowercase letters should not be recognized as a valid hexadecimal number. See below . Enter a hexadecimal number: b6f The binary equivalent is not found. Invalid hexadecimal number. Make sure to include header and step comments in your program.
