Question

how do you code a recursive function that converts hex to decimal and decimal to hex in python 3? without using the built-in python functions that convert directly from integer to hex and vice-versa like int() and hex()?

I'm having trouble setting up the parameters so please include notes/comments in your code.

Also, for checking if the input is valid, is my code correct? (please refer to the photo)

def is_valid_input(x):
"""Check if the input provided is valid"""
if x!=1 or x!=2:
return False
return True

• Prompt the user to choose the type of conversion to perform:
• Enter 1, to convert from decimal to hex
• Enter 2, to convert from hex to decimal
• For input values other than 1 or 2, prompt the user again to input a valid value.
• Create a recursive function named hexToDecimal() that takes in a hexadecimal value and returns the
equivalent decimal number.
• Create another recursive function named decimalToHex () that takes in a decimal value and returns the
equivalent hexadecimal number.

Sample Input 0
1
15655185
Sample Output 0
Enter (1) to convert from decimal to hex, (2) to convert from hex to decimal: 1
Enter a decimal value: 15655185
The hexadecimal equivalent of 15655185 is EEE111.
Sample Input 1
2
EEE
Sample Output 1
Enter (1) to convert from decimal to hex, (2) to convert from hex to decimal: 2
Enter a hexadecimal value: EEE
The decimal equivalent of EEE is 3822.
Sample Input 2
0
1
47793
Sample Output 2
Enter (1) to convert from decimal to hex, (2) to convert from hex to decimal: 0
Invalid input.
Enter (1) to convert from decimal to hex, (2) to convert from hex to decimal: 1
Enter a decimal value: 47793
The hexadecimal equivalent of 47793 is BAB1.
