Question

How to convert a number to any base in Python

Answer 1

def to_base(n, base):
    digits = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
    if n == 0:
        return "0"
    result = ""
    while n > 0:
        n, remainder = divmod(n, base)
        result = digits[remainder] + result
    
    return result


print(to_base(25, 2))   # binary → 11001
print(to_base(25, 8))   # octal → 31
print(to_base(25, 16))  # hex → 19
print(to_base(25, 36))  # base‑36 → P



'''
The decimal number 25 is represented as P in base-36. 
Base-36 uses digits 0-9 followed by letters A-Z (where A=10, B=11, ..., P=25, ..., Z=35) 
to represent values.
