Write a program using any high$-$level language $($Python$)$ to help you convert from binary, octal,

hexadecimal and decimal numbers $($integers or floating point numbers$).$

Your program would

ask the users to enter a number in binary or decimal

ask the users what type of number it is $($binary or decimal$)$

check to make sure the number is legal $($a decimal number contains only $0-9).$ If the number is not legal, it

should error out!

If the number is legal, convert the number to the other $3$ types $($Hint: There are a total of $4$ types: binary,

octal, hexadecimal, decimal$)$

Your program needs to do basic error$-$checking
