Overview : History of Python

Python was developed by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands in the late 1980s, as an improvement to the ABC programming language. Its implementation started in late 1989 and was first released in 20 February 1991. Guido Van Rossum managed this open source project until 12 July 2018, when he announced his permanent break (exit) from his responsibilities as lead developer of the project.

FAQs

It's a misconception that Python requires high-performance computers and laptops. Python works well even if you have old laptop with poor configuration like 4GB RAM and i3 processor. If you need to handle large datasets, you would obviously need more system memory with powerful processor. In nutshell, laptop with not-so-high configuration is enough for practice python programming but needs high-performance system for memory intensive operations.

Python is used for a variety of purposes ranging from API building to Artificial Intelligence. You should focus on basics of Python and then you can jump to advanced programming concepts. There are several packages in Python for Data Science which are easy to use but you need to have prior knowledge of statistics. If you already possess intermediate knowledge of statistics, these packages would be a piece of cake for you. Make your schedule and follow it with no cheat. You can learn basic of python in a week if you spend 8 hours per day with a lot of practice. Once done, start using different statistics algorithms using Python. You can make use of the publicly available datasets for practice

Python is open-source only and available for free. The only difference you may see is different editors for coding Python. Some of the popular ones are Spyder, Microsoft Visual Studio, PyCharm etc. Some of the popular notebooks are Jupyter, Google Colab, Azure Notebooks. They ease writing codes with beautiful interface but programming and concepts of Python are exactly same everywhere so you should focus on learning Python rather than the different editors. You will be asked about programming questions in interviews. Interviewers don't care much about editor you use.
