About the course

This master class is designed to ramp-up your coding skills on Python with focus on a pythonic approach towards problem-solving. You will undergo a smooth transition into the world of Python coding while learning the internals and intricate details of Python syntax, datatypes and language design in general. After successful completion of this course, you should be competent enough to crack most technical coding job interviews on Python skillsets. Kindly note that this training class will be fast-paced with live coding demonstations and discussions (similar to most corporate training sessions delivered by the instructor).

Target audience

This training class is intended for engineers and coding enthusiasts who have basic understanding and coding skills in other programming / scripting languages and are interested in acquiring coding skills on Python language.

Prerequisites

Participants should be familiar with programming in any programming language. Most comparative examples demonstrated in the training classes will be based on the assumption that the participant is familiar with C/C++/Java programming concepts.

Course Objectives

Learn the Pythonic approach towards problem-solving.
Unlearn traditional coding practices from other programming languages and think in terms of Python.
Learn the features, syntax and best practices in Python coding.
Deep dive in to the dynamic nature of Python language design for writing code.

- Python indentation rules
Flow control constructs:
- Conditions
- Loops
- Iterations
- Exception handling
Basic builtin functions: print(), input(), dir(), type()

Python language features and terminologies

Python as a dynamic programming language.
Static vs Dynamic typing – the unsettled debate.
Gradual typing syntax support in Python code.
Statements are not expressions.
The rationale behind the lack of ++ and -- operators.
Understanding immutable and hashable objects.
The “==” vs “is” operator.
The “in” operator.
Functions vs methods vs type constructors.
Type casting vs type constructors.
Names, Objects, Values, Types and Attributes.
Variables vs Attributes.

Module 3

Python design paradigms

Pythonisms (with demonstrations)

Everything in Python are ultimately objects.
All identifiers are names that act as references.
Python programs are modules.
Functions and classes are callable objects.
Methods are attributes that refer to callable objects.
Statements are not expressions.
Every object express boolean truthiness.
Every object express an offical and/or an unoffical string representation.
Every object can be introspected in runtime
Popular Python Zen idioms:
- “Errors should never pass silently (unless explicitly silenced)!”
- “There should be one and preferably only one obvious way to do it!”
- “In the face of ambiguity — refuse the temptation to guess!”

Python programming styles and paradigms
