Python

• Python is a Programming language which is Developed by Guido van Rossum
• Zen of Python
  
• Python is an open source language, Python new features or any changes are done with PEP (Python Enhancement Proposal)
• Python is used every where
  • CLI
  • Web Applications
  • Scripting
  • AI/ML
  • Data
• Python has different Flavors
  • Python (CPython): This is most popular
  • Jython (Implemented in Java)
  • IronPython (Implemented in .net)

How python Works

• How it looks like
  
• How Python Runs the code
  
• Python installation also will have a component memory manager which is used for Automatic Garbage Collection.

Naming Conventions

• For Naming variables we have following Conventions (irrespective of language)
  • Pascal Casing:
    • First Letter of a variable has to be Upper Cased
    • If your Variable is Multi Word then each word first Letter has to be Upper Case
    • Examples:
      • if you want to a name variable test: Pascal casing Test Test = 100
      • if the name of the variable is mytest: Pascal Casing MyTest
  • Camel Casing
    • First Letter of a variable has to be lower Cased
    • If your Variable is Multi Word then apart from first work all others word first Letter has to be Upper Case
    • Examples:
      • if you want to a name variable test Camel casing test test = 100
      • if the name of the variable is mytest: Camel Casing myTest
  • Snake Casing
    • First Letter of a variable has to be lower Cased
    • All words start with small case using _ as seperator
    • Examples:
      • if you want to a name variable test Snake casing test test = 100
      • if the name of the variable is mytest: Snake Casing my_test
• For Python naming Conventions Refer Here
• Variables will use Snake casing

Python Operators

• programiz Refer Here
• Arthimetic and Assignment Operators
• Findout Numeric Operators in Python
• Try the following
  • area of circle by passing radius = 5
• When we write an Expressions if it has multiple operators programming languages evaluate the one operator after another based on priority
• This priority is defined as operator precedence
