Functions and Modules in Python for Data Science
Introduction
Functions and modules are important concepts in Python programming. In this functions and modules in Python for data science tutorial for beginners free, you will learn how to organize your code and reuse it efficiently. These concepts help in writing clean and structured programs.
What are Functions in Python
A function is a block of code that performs a specific task. Functions help reduce repetition and make code easier to manage.
Creating a Function
Example of Function
print(“Welcome to Data Science”)
greet()
Function with Parameters
You can pass values to a function using parameters.
print(“Hello”, name)
greet(“Sam”)
Function with Return Value
Functions can return values using the return keyword.
return a + b
result = add(5, 3)
print(result)
What are Modules in Python
A module is a file that contains Python code such as functions and variables. Modules help organize large programs into smaller parts.
Using Built-in Modules
Example
print(math.sqrt(16))
Creating Your Own Module
Example
Create a file named mymodule.py and add:
return a + b
Then use it in another file:
print(mymodule.add(2, 3))
Applications in Data Science
Functions and modules are used to organize code in data analysis, machine learning models, and automation tasks. They make large projects easier to manage.
