This article will try to answer all your queries about making a career as a Python Developer.
Before we learn how to become a python developer, let’s explore why you should learn Python.
Why Learn Python?
To simply say, Python is at #3 in the TIOBE Index (for popularity of programming languages) for 2019. And in the list of top programming languages for 2019 by the IEEE Spectrum, it is at #1. Python is great both for beginners to programming and for experienced coders. But what makes it even better is that Python is being preferred for domains like Data Science, Machine Learning, and Artificial Intelligence. It has great analytical capabilities and multiple libraries geared for these domains, it is a very powerful general-purpose language. Ready to learn Python? Now, let’s find out how to do it to get a job as a Python Developer.
How to Become a Python Developer?
Below is the Python developer roadmap –
- Decide to learn Python; decide why you want to do it.
- Follow online tutorials. DataFlair has this comprehensive list of Python tutorials where you’ll find everything at one place. Keep practising as you learn.
- Read some good books on Python and enroll in an online Python course. DataFlair just launched its Certified Python Course to help you learn Python. Here, you’ll understand the concepts, solve practicals and assignments, and even work on some exciting projects.
- Keep reading the official Python documentation for different constructs.
- Take a peek into the source code of your favorite Python package to know how it works.
Follow these steps to become the next Python Developer –
1. What to Learn in Python?
- Learn the basics. Learn about its history, syntax, installation, and some basic constructs like statements, variables, and operators.
- Find out about the applications of Python. Also understand the differences between Python 2 and Python 3.
- Learn about basic data structures like lists, sets, and dictionaries.
- Understand important concepts like decision making and loops.
- Learn how to create a virtual environment.
- Move on to functions and recursion.
- Get started with object-oriented concepts like classes and methods, and inheritance and overloading.
- Find out about modules and packages, and get some experience with common modules like os, namedtuple, and calendar.
- Learn file handling. Learn about more complex topics like generators and decorators, and shallow and deep copying.
- Also, learn to generate and use random numbers and regular expressions.
- Learn about more complex topics like networking, XML processing, and multiprocessing.
- Learn to build GUIs with Python.
- Find out about exceptions and how to handle them.
- Learn to use SciPy, NumPy, and Pandas.
- Learn to debug, unit-test, log, serialize, and access the database.
2. Things to master Python
You should now learn to work on a framework. Python has some very powerful frameworks like Django, Flask, and CherryPy. You can begin with Django, which is a very powerful framework following the DRY (Don’t Repeat Yourself) principle. It makes work easier for you and takes care of trivial things.
ORM stands for Object Relational Mapping. This is a way to query and manipulate data from a database using an object-oriented paradigm. You can learn to use ORM libraries like SQLAlchemy and Django ORM. This is easier and faster than writing SQL.
Changes to a code multiple times by multiple people can ultimately break it. You should learn GitHub and its simple terms like push, pull, fork, and commit if you want to implement version control (you should).
3. Build Projects in Python
You now have enough skills; building some personal python projects will give you confidence. You can also build something to try and solve an actual problem you face. Once you feel confident enough, you can then build for popular open-source projects like Django.
