Functions

Functions are reusable blocks of code that perform a specific task. They help in organizing and managing the code efficiently.

Use the def keyword to define a function.

Code:

def greet(name):

return f"Hello, {name}!"

print(greet("Alice"))

Functions can accept arguments to customize their behavior.

Code:

def add(a, b):

return a + b

print(add(3, 5))

You can provide default values for function arguments.

Code:

def greet(name="Guest"):

return f"Hello, {name}!"

print(greet())

print(greet("Alice"))

Functions can accept a variable number of arguments using *args and **kwargs.

Code:

def print_numbers(*args):

for number in args:

print(number)

print_numbers(1, 2, 3, 4)

def print_info(**kwargs):

for key, value in kwargs.items():

print(f"{key}: {value}")

print_info(name="Alice", age=25, city="New York")
