Understanding Python's divmod Function: Quotient and Remainder

In Python, the built‑in divmod function returns a tuple containing both the integer quotient and the remainder of a division operation, effectively combining the results of a // b and a % b.

The function signature is divmod(a, b), where a and b are numeric values; it returns (quotient, remainder). The result type is a tuple. In Python 2.x, complex numbers were not supported, but they are allowed in later versions.

Example usage:

print(help(divmod))

# Help on built‑in function divmod in module __builtins__:

# divmod(x, y) -> (quotient, remainder)

# Return the tuple ((x - x % y) / y, x % y). Invariant: div * y + mod == x.

print(divmod(7, 2))   # (3, 1)

print(divmod(8, 2))   # (4, 0)

print(divmod(1+2j, 1+0.5j))   # ((1+0j), 1.5j)
