Decimal to Binary and Other Bases

Programs with input · Advanced · about 15 min

Read a whole number (0 or more), then a base from 2 to 16, one per line. Print the number written in that base, as 13 in base 2 is 1101. Digits above 9 are the capital letters A to F, so 255 in base 16 is FF. If the base is not from 2 to 16, print Base must be from 2 to 16.

Python's bin() and hex() only cover some bases, so work it out with division.

The prompts inside input() are not checked, only what you print.

Examples

You type:

13
2

The program prints:

13 in base 2 is 1101

You type:

255
16

The program prints:

255 in base 16 is FF

n = int(input("Number: "))

base = int(input("Base (2 to 16): "))

# Print n written in the base

Typed input, one line for each input()
