Constants

  • Constants
  • Definition
    • Constants are defined as those (Data) Values that do not change (i.e., remain the same) every time a Python Program is executed
  • Examples – Constants
  • Example 1 – A String Constant
    • Hazrat Muhammad S.A.W.W.
  • Example 2 – An Integer Constant
    • 7
  • Example 3 – A Float Constant
    • 86
  • Only Change is Constant
  • My Respected Teacher said
    • The only thing that is Constant in this world is
      • Change
    • Always! Be Kind. Always! Be Humble.
      • If you are Strong, Wealthy and Powerful Today, then don’t Oppress the Weak / Poor / Needy People
        • Very Soon, Time will Change, and you will also be Weak Poor and Powerless
      • Always Remember!
        • All praise is for Almighty Allah, who has control over everything

Types of Constants

  • Types of Constants
  • Two main broad categories of Constants are
    • Numeric Constants
    • String Constants
  • Types of Numeric Constants
  • The two main types of Numeric Constants are
    • Integer Constants
    • Float Constants
  • Integer Constants
  • Definition
    • Integer Constants are defined as those (Integer) Values that do not change (i.e., remain the same) every time a Python Program is executed
  • Purpose
    • The main purpose of the Integer Constants is to
      • Represent Integral Values
  • Important Note
    • An Integer Constant
      • Must have at least One Digit
      • Cannot have a Decimal Point
      • Can be either Positive or Negative
        • By default, an Integer Constant is Positive
  • Examples - Integer Constants
  • Example 1
    • 0
  • Example 2
    • -7
  • Example 3
    • 571
  • Example 4
    • -1000
  • Example 5
    • 2000000
  • Example 6
    • -9000000
  • Float Constants
  • Definition
    • Float Constants are defined as those (Float) Values that do not change (i.e., remain the same) every time a Python Program is executed
  • Purpose
    • The main purpose of the Float Constants is to
      • Represent Floating-Point Values
  • Important Note
    • A Float Constant
      • Must have
        • An Integer (before the Decimal Point)
        • A Decimal Point
        • A Fractional Part (after the Decimal Point)
      • Can be either Positive or Negative
        • By default, a Float Constant is Positive
  • Example – Three Parts of a Float Constant
  • Consider the following Float Constant
    • 86
  • Part 1 – Integer (before the Decimal Point)
    • 3
  • Part 2 – Decimal Point
    • .
  • Part 3 – Fractional Part (after the Decimal Point)
    • 86
  • Examples - Float Constants
  • Example 1
    • 5
  • Example 2
    • – 0.25
  • Example 3
    • =   = 0.25
  • Example 4
    • – 25.00
  • Example 5
    • = 0.01

Printing Integer Constants (or Integer Values) on Output Screen

  • Important Note
  • For all the Tasks in this Chapter, In Sha Allah, the Concepts studied in the previous Chapter may also be used including
    • print() Function
      • To Display Textual Data on the Output Screen
    • IPython Module
      • To Display Image, Video and Audio Data on the Output Screen
    • Escape Sequences
      • To Improve overall Formatting of the Data to be displayed on the Output Screen
  • For details on print() Function, IPython Library and Escape Sequences
    • See Chapter 4 – Basics of Python

  • Difference Between Normal Text in print() Function and Integer Constant
Code Fragments
  • Consider the following two Code Fragments
    • Code 1
      • print(“99 names of Allah”)
    • Output of Code 1
      • 99 names of Allah
    • Code 2
      • print(99, “names of Allah”)
    • Output of Code 2
      • 99 names of Allah
Analysis and Conclusions
  • Analysis of Python Program
    • Output of Code 1 is exactly same as Output of Code 2
      • However, in Code 1
        • 99 is a String
      • Whereas, in Code 2
        • 99 is an Integer Constant
Conclusions
  • Normal Text and Integer Constants in print() Function are treated differently

TODO and Your Turn

String Constant

  • String
  • Definition
    • A String is defined as a Sequence of Characters
  • String Constants
  • Definition
    • String Constants are defined as those Fixed Sequence of Characters that do not change (i.e., remain the same) every time a Python Program is executed
  • Purpose
    • The main purpose of the Float Constants is to
      • Represent Fixed Sequence of Characters
  • Important Note
    • A String Constant may contain
      • Characters
      • Numbers (Integer and / or Float)
      • Special Characters (for e.g., $, #, @ etc.)
      • Punctuation Marks (for e.g., Full Stop, Comma etc.)
      • Spaces
  • Types of String Constants
  • The two main types of String Constants are
    • String Constant Comprising of a Single Character
    • String Constant Comprising of Multiple Characters
  • Examples - String Constant Comprising of a Single Character
  • Example 1
    • A
  • Example 2
    • $
  • Example 3
    • a
  • Example 4
    • @
  • Example 5
    • %
  • Examples - String Constant Comprising of Multiple Characters
  • Example 1
    • Allah
  • Example 2
    • Hazrat Muhammad (S.A.W.W.)
  • Example 3
    • Al-Masjid An-Nabawi, Al Haram, Madina 42311, Saudi Arabia
  • Example 4
    • Love and Respect the Humanity
  • Example 5
    • To learn any Task completely and correctly, First focus on Accuracy then on Speed

  • Difference Between Normal Text in print() Function and Integer Constant
Code Fragments
  • Consider the following two Code Fragments
    • Code 1
      • print(“Allah loves those who love the humanity”)
    • Output of Code 1
      • Allah loves those who love the humanity
    • Code 2
      • print(“Allah” + “loves those who love the humanity”)
    • Output of Code 2
      • Allah loves those who love the humanity
  •  
Analysis and Conclusions
  • Analysis of Python Program
    • Output of Code 1 is exactly same as Output of Code 2
      • However, in Code 1
        • Allah is a String
      • Whereas, in Code 2
        • Allah is String Constant
Conclusions
  • Normal Text and String Constants in print() Function are treated differently

Chapter Summary

  • Chapter Summary

In this Chapter, I presented the following main concepts:

  • Constants
    • Constants are defined as those (Data) Values that do not change (i.e., remain the same) every time a Python Program is executed
  • The two main types of Numeric Constants are
    • Integer Constants
    • Float Constants
  • Integer Constants
    • Integer Constants are defined as those (Integer) Values that do not change (i.e., remain the same) every time a Python Program is executed
  • Float Constants
    • Float Constants are defined as those (Float) Values that do not change (i.e., remain the same) every time a Python Program is executed
  • String
    • A String is defined as a Sequence of Characters
  • String Constants
    • String Constants are defined as those Fixed Sequence of Characters that do not change (i.e., remain the same) every time a Python Program is executed
  • The two main types of String Constants are
    • String Constant Comprising of a Single Character
    • String Constant Comprising of Multiple Characters

In Next Chapter

  • In Next Chapter
  • In Sha Allah, in the next Chapter, I will present a detailed discussion on
  • Variables in Python
