   print(“Hi” * 10)
5. Comments
   single line #
   multiline comments “””
6. Concatenation operator +
7. Variables
   • int
   • string
   • boolean
   • float
   • None – unline Java there is no null available in python instead use None
8. type() function
9. Variable’s id and is Operator
10. Operators
    • addition +
    • subtraction –
    • multiplication *
    • power of **
    • division /
    • int division //
    • modulus %
11. input() function
12. type conversion / type casting
    • int(’10’)
    • str(9)
    • float(‘10.5’)
    • bool(‘True’)
13. String
    • string with single quote ‘string’
    • string with double quote “string”
    • heredoc – string with triple quote ”’ or “””  
      heredoc_var = ”’
      this is line 1
      this is line 2
      this is line 3
      ”’
14. Formatted String
    print(f”2 * 2 = {2 * 2}”)
    print(f”Hello {fname} {lname}”)
15. String Functions
    • len(‘string’) – this is general purpose function can be used for string and list also
    • ‘string’.upper()
    • ‘StrinG’.lower()
    • ‘this is string’.capitalize()
    • ‘this is string’.title()
    • ‘rain in spain’.find(‘spain’)
    • ‘replace x with y’.replace(‘x’, ‘y’)
    • ‘this is main string which contains substring’.find(‘substring’) – this returns index number if found else return -1
    • ‘substring’ in ‘this is main string which contains substring’ – this returns boolean value
16. Math functions
    • round(7.3)
    • abs(-1234)
    • math.ceil(7.3)
    • math.floor(7.3)
    • format decimal point
      print(“{:.2f}“.format(7.3333333333333)
17. Conditional Statements:
    1. if
    2. if…else
    3. if…elif…else (Ladder if)

    3. Abstraction
    4. Inheritance
    5. Static Method
    6. Method Overriding
    7. Private and Public data and variables
    8. Polymorphism
26. Regular Expression
