Python divmod() Function
The divmod() function in Python returns a tuple containing the quotient and the remainder when dividing two numbers. It's a quick way to get both results in one line.
Syntax
divmod(a, b)Parameters:
a– The dividend (numerator)b– The divisor (denominator); must not be 0
Returns:
- A tuple
(quotient, remainder)
Example 1: Integer Division
result = divmod(10, 3)
print(result)(3, 1)Why? Because 10 ÷ 3 = 3 with a remainder of 1.
Example 2: Assigning Quotient and Remainder
q, r = divmod(22, 5)
print("Quotient:", q)
print("Remainder:", r)Quotient: 4
Remainder: 2Example 3: Using with Floats
print(divmod(7.5, 2.5))(3.0, 0.0)Use Cases
- Efficiently calculate both quotient and remainder in a single step
- Common in loops where both values are needed
- Useful in modular arithmetic problems
Common Mistakes
- Passing 0 as the second argument will raise
ZeroDivisionError - Both arguments must be numeric (int or float)
Interview Tip
In coding interviews, divmod() can simplify logic in problems involving floor division and modulo operations.
Summary
divmod(a, b)returns(a // b, a % b)- Works with both integers and floats
- Returns a tuple with two elements: quotient and remainder
Practice Problem
Write a program that reads two integers from the user and prints their quotient and remainder using divmod().
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
q, r = divmod(a, b)
print("Quotient:", q)
print("Remainder:", r)
