HELP! I don't know binary, hexadecimal, octal, and bit-wise

Question

I haven\'t learned this in programming class before, but now I need to know it. What are some good resources for learning these numbers and how to convert them? I pretty much am

Answer 1

Here my code in Python for Numeral conversions(2,8,10,16) from any to any. it may help you.

class Conversion:

    def __init__(self):
        pass

    def dec_to_any(self, data, base):
        return base(data)

    def any_to_dec(self, data, base):
        return int(data, base)


def main():

    menu ={1: 'dec to bin', 2:'dec to oct', 3:'dec to hex', 4: 'bin to dec', 5: 'bin to oct', 6:'bin to hex', 
           7: 'oct to bin', 8: 'oct to dec', 9: 'oct to hex', 10: 'hex to bin', 11: 'hex to oct', 12: 'hex to dec'}

    target_base = {'bin': bin,'oct': oct, 'hex': hex}    
    src_base = {'bin': 2,'oct': 8, 'hex': 16}

    choice=int(input(str(menu)+"\nEnter your choice: "))

    src, target = menu[choice].split()[0], menu[choice].split()[2]

    c=Conversion()
    val =input("Enter the value :")

    if(src == "dec"):
        val =int(val)
        value= c.dec_to_any(val, target_base[target])
        print('Value is :', value)

    elif(target == "dec"):
        value = c.any_to_dec(val, src_base[src])
        print('Value is :', value)

    else:
        val = c.any_to_dec(val, src_base[src])
        value= c.dec_to_any(val, target_base[target])
        print('Value is :', value)

if __name__ == '__main__':
    main()
