5 Free Courses to Master Python for Data Science

 5 Free Courses to Master Python for Data Science

Want to learn Python to kickstart your career in data? Here are five free courses to help you master Python for data science

Learning Python is super helpful if you’re looking to switch to a data career. But there is a lot to learn: from the basics of Python programming to data analysis, machine learning, and cracking coding interviews. So how do you find the best resources to learn them all?

To help you, we’ve compiled a list of courses to help you master Python for data science. Whether you are a beginner or an experienced professional looking to refresh your Python skills, these courses are for you. The suggested courses will help you learn the following:

• Basics of Python
• Python data science libraries 
• Data analysis and machine learning with Python
• Data structures and algorithms with Python

Let’s get started.

 

1. Python for Beginners 

The Python for Beginners course from Mosh will help you become familiar with the absolute basics of Python programming. 

In about an hour, you can get up in running with the following basics:

Variables 

Receiving input 

Type conversions 

Strings 

Operators and operator precedence 

If statements 

While and for loops 

Lists and tuples

2. Intermediate Python Programming 

 

Now that you know the basics, you can take this Intermediate Python Programming course. This course starts out by discussing the various Python built-in data structures. And proceeds to more advanced features of the language.

The topics covered in this course include:

Python’s built-in data structures 

Collections 

Itertools 

Lambda functions 

Exceptions and errors 

Logging 

Working with JSON 

Random number generation 

Decorators 

Generators 

Multithreading and multiprocessing 

Function arguments 

Shallow vs. deep copy 

Context managers

3. Data Analysis with Python

Once you have a good grasp of Python, you can proceed to learn about the various Python data science libraries. 

The Data Analysis with Python certification from freeCodeCamp will help you learn all the necessary Python data science libraries:

• NumPy
• Pandas
• Matplotlib
• Seaborn

You will also get to build a few data analysis projects. Which you should complete to receive the Data Analysis with Python certification.

4. Machine Learning with Python and Scikit-Learn 

 You should now be comfortable programming with Python and working with Python data science libraries. And you can now start exploring machine learning.

Machine Learning with Python and Scikit-Learn will help you learn about the theory (how machine learning algorithms work) and the implementation of machine learning algorithms with scikit-learn. This course will also learn how to approach and plan machine learning project, build, and deploy machine learning applications.

Here’s an overview of the topics covered: 

Linear regression and gradient descent 

Logistic regression for classification 

Decision trees and random forests 

How to approach machine learning projects 

Gradient boosting machines with XGBoost

Machine learning project from scratch 

Deploying a machine learning project with class

5. Data Structures and Algorithms in Python

 

In the data science interview process, you should first crack coding interviews to proceed to the next stages. To crack them and to make your coding practice sessions more effective, you should first have a strong foundation in data structures in algorithms.

Data Structures and Algorithms in Python is a free course that’ll help you learn the essential data structures and algorithms—with focus on Python.

Just take a structures this data structures in algorithm scores the following this Data Structures and Algorithm Sports will help you learn the following topics 

Binary search, linked lists, and complexity 

Binary search trees, traversal, and recursion 

Hash tables and Python dictionaries

Sorting algorithms, divide and conquer 

Recursion and dynamic programming 

Graph algorithms 

Python interview questions, tips, and advice
