What is python
- It is a language
- Human-readable syntax and well Documented
- Open Source (Free)
- Powerful scripting language with simple Syntax
- Used by many data scientists and developers
- Python language created by Guido van Rossum (Benevolent Dictator for Life).
- First Python version released in 1991
- Python 2 released in 2000
- Python 3 released in 2008
- Python 3 introduced to overcome future code expanding
- Python 3 is NOT fully backward compatible with Python 2
- Python 2 is frozen and supported until 2020. Good features from Python 3 are back-ported.
Which one to use? Python 2 or Python 3
- Python 2 is NOT same as Python 3. There are minor changes.
- There are some incompatibilities, the code in Python 2 may not always run in Python 3 and vice-versa.
- All important packages like NumPy, SciPy, and Matplotlib are available for both Python 2 and Python 3
- We are using Python 3 in our courses.
Installing Python & Python IDEs
Writing and executing python programs
- Python has many options to write and execute a program.
- You can use Text Editors or Command line interfaces or Notebook or an IDE.
- We will use Spyder IDE in our courses.
- Anaconda distribution has all the required software’s inbuilt. We just need to download and install it.
Installing Python, Anaconda
- Download and install Anaconda3 by visiting anaconda.org.
- It automatically installs
- Jupyter notebook
- Spyder IDE
- Spyder is what we need for our coding.
Spyder- Python IDEs
- Spyder (formerly Pydee) is an open source cross-platform IDE for the Python language.
- Editor with syntax highlighting and code completion.
- Has an interactive console to execute and check the output of the code.
- Testing and debugging is relatively easy.
- Best IDE if you are coming from an R-Studio or MATLAB background.
- Spyder also provides an object inspector that executes in the context of the console. Any objects created in the console can be examined in the inspector.
