Method Overloading in Python

Java-style overloading — same method name, many signatures at compile time — is not how Python works. A second def with the same name replaces the first. To accept optional arguments, use defaults, *args, **kwargs, or functools.singledispatch. Overriding in a child class is normal and common.

Be honest: Python “overloads” via defaults and *args, not via many typed defs. Contrast overloading (same class, many signatures) vs overriding (child replaces parent). Freshers mix those two words.

Method Overloading in Python — output — 5 then 5. One function, default b=0 — Python’s way, not two add methods.

Exam tip

Overloading vs overriding in Python.

Example

# Overloading idea
def add(a, b=0):
    return a + b

print(add(2, 3))
print(add(5))

Method Overloading in Python — output: 5 then 5. One function, default b=0 — Python’s way, not two add methods.

Short notes

DefNo Java-style overload
RuleLater def wins
RememberUse defaults / *args
