Python Number Converter
Generally speaking, practiced skill cannot be easily forgotten. It is far better to go through the process and practice converting a number, rather than to memorize the process.
Before we get started, have a look at the Tools Page to get started with a Python Interpreter we could use for this exercise.
Number to Printable Hex
def nibble_to_ascii(nibble: int) -> str:
"""
This is a comment
Input: Nibble (4-bits)
Output: Single character HEX as a string
Example: Input = 10, Output = 'A'
Example: Input = 8, Output = '8'

return table[nibble]

# Forever loop
while True:
# Integer divide using the // operator
quotient = number // 16
# Get the remainder using the % operator
remainder = number % 16
# Accumulate result
answer = nibble_to_ascii(remainder) + answer
# Set the number we need to use for next time
number = quotient
# We break the "loop" when division turns to zero
if (quotient == 0):
break
return "0x" + answer
print(to_hex(123456789))
print(to_hex(0b1010101))
print(to_hex(0xDEADBEEF))Exercise
Write a function to_binary() that takes a number, and returns the string equivalent version of the number in binary. You can borrow the template above of to_hex() function and most of the logic might be similar except that we would be dividing number by 2 rather than 16.
