    • 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)
