Today I will define the further concepts of python programming language.
Note: Indentation is very important in Python code. Without indentation, it always gives an error of indentation.
I have already told you.
Download Python LanguageTutorials and give star on GitHub if those files are helpful for you.
In this article you will understand the following:
These four concepts you have already used in another programming language. But in this language, they are different for writing. Python makes shortcode for faster typing and execution.
  1. Numbers:
    In Numbers, Python works as a Calculator. Because we can calculate any calculation without another code. Simply type number and operators then python gives output faster.

    Example:
    1. val = 2 + 5
    3. print(val ,"\n")
    5. val = 2 * ( 9 + 4 )
    7. print(val,"\n")
    9. val = ( 30 - 4 * 5 ) / 6
    11. print(val,"\n")
    13. val = 7 / 5
    15. print(val,"\n")
    17. val = 5 ** 2
    19. print(val,"\n")
    21. val = -5**2 #this code gives output -25 but output should be 25
    22. # so always use parenthesis (-5)**2
    23. print(val,"\n")
    25. val = (-5)**2
    27. print(val,"\n")
    29. val = 5 // 2
    31. print(val,"\n")
    Output:
    7
    26
    1.6666666666666667
    1.4
    25
    -25
    25
    2

  2. Strings:
    Python Language gives more functionality to handle the string easily.

    Python language has many concepts for accessing characters in the string at any position with different types.

    Example:
    1. print('NeErAj KuMaR' ,"\n")
    2. print("\"NeErAj KuMaR \"" ,"\n")
    3. print('C:\windows\name' ,"\n")
    4. print(r'C:\windows\name' ,"\n")
    5. print('Py' 'thon' ,"\n")
    6. word = 'NeErAj'
    7. print("+----+----+-----+------+")
    8. print("| N | e | E | r | A | j")
    9. print("+----+----+-----+------+")
    10. print("| 0 | 1 | 2 | 3 | 4 | 5 ")
    11. print("| -6| -5| -4| -3| -2|-1")
    12. print(word[0] ,"\n")
    13. print(word[5] ,"\n")
    14. print(word[-1] ,"\n")
    15. print(word[-6] ,"\n")
    16. print(word[0:3] ,"\n")
    17. print(word[2:5] ,"\n")
    18. print(word[2:]+word[:5] ,"\n")
    19. print(len(word) ,"\n")
    Output:
    NeErAj KuMaR
    "NeErAj KuMaR "
    C:\windows\name
    Python
    +----+----+-----+------+
    | N | e | E | r | A | j
    +----+----+-----+------+
    | 0 | 1 | 2 | 3 | 4 | 5
    | -6| -5| -4| -3| -2|-1
    N
    j
    j
    N
    NeE
    ErA
    ErAjNeErA
    6

  3. List:
    The list is also the same as the arrays concept in python language. You can access values with various types.

    But in Python, a new way with a colon( : ) gives access data from the list.

    Example:
    1. value = [ 1 , 3 , 2 , 4 , 5 ]
    2. print(value ,"\n")
    3. print(value[:] ,"\n")
    4. print(value[2] ,"\n")
    5. print(value[:4] ,"\n")
    6. print(value+[ 12 , 13 , 54 , 33 , 42 ] ,"\n")
    7. value.append(43)
    8. print(value ,"\n")
    9. value[0:2]=[ 9 , 3 , 7]
    10. print(value ,"\n")
    Output:
    [1, 3, 2, 4, 5]
    [1, 3, 2, 4, 5]
    2
    [1, 3, 2, 4]
    [1, 3, 2, 4, 5, 12, 13, 54, 33, 42]
    [1, 3, 2, 4, 5, 43]
    [9, 3, 7, 2, 4, 5, 43]

  4. Loop:
    In Python, Language looping is easy for getting the fast output. In Looping of Python language, use function range().

    Which runs automatic loop at the desired value in range() function.

    end=’,’ this code also useful in the loop. It denotes that each time loop finish, it adds automatic comma ‘,’ after each loop.

    Example:
    1. a, b = 0, 1
    2. while b < 15:
    3. print(b, "\n")
    4. a, b = b, a + b
    5. a, b = 0, 1
    6. while b < 15:
    7. print(b, end = ', ')
    8. a, b = b, a + b
    9. print("\n")
    10. for i in range(5):
    11. print(i, "\n")
    12. for i in range(-10, -100, -10): #-10 denote starting value# - 100 end value
    13. print(i, "\n")# - 10 denote difference each time in loop
    14. OS = ["windows", "linux", "mac"]
    15. for os in OS:
    16. print(os, len(os), "\n")
    17. for n in range(2, 10): #calculate number is prime or not prime
    18. flag = 0
    19. for x in range(2, n):
    20. if n % x == 0:
    21. flag = 0
    22. break
    23. else :
    24. flag = 1
    25. if flag == 0:
    26. print(n, " Not Prime\n")
    27. else :
    28. print(n, " Prime\n")
    Output

I hope you will easily understand my code for learning the Python language.
Thank you.
