      x = 6
      y = 2
      print(x ** y)# ** reprise the power of like 6^2 = 36
      print(x // y)# this is tricky one

      # so '//' this operator divide the and round down to zero
      # if it was
      x = 7
      y = 2

      print(x // y) # the result will be 3.5 in normal division '/' here it takes the extra after the dot '.' out

      a = [10, 20]
      b = a
      b += [30, 40]
      print(a)
      print(b)

      # we can modify the list we can’t modify strings the above is the list so it’s when modified it reflects on both

      In Python, When we join two non-Boolean values using a and operator, the value of the expression is the second operands, not True or False.

      this is and operator so and operator compare both value if first value match to variable and then go for second value and print second variable value as a result for non boolen value.

      By using floor division we always round off to smaller value if you divide 18÷4 you get 4.5 but as 18 is negative so we round it off to smaller value -4.5 to -5 .
      Thank you.

    Hi, in Q8, explanation is:
    In Python, When we join two non-Boolean values using a and operator, the value of the expression is one of the operands, not True or False.
    but should be:
    In Python, When we join two non-Boolean values using a and operator, the value of the expression is the second of the operands, not True or False.
    With operator OR is the first: am I wrong?

    I want an explanation of example 8, suppose instead of the list if I will give string why the value of a is not concatenating with b?

    Please reply to this

    c="Hi"
d=c
d+="Himanshu"
print(c)

    Output:
    ‘Hi’

      Hi Himanshu, Those are different variables pointing to the different memory addresses. For Example:

      c="Hi"
d=c
d+="Himanshu"

print(id(c))
print(id(d))

      Output:

      Hi

      Because you have stored a string in the variable – c
      The += operator does not work in the similar fashion as it does for list, tuples and numeric values.
      Change the values to a tuple or a list or a number and you will see the difference.

      str data type is immutable. Therefor once you created an str object you can’t modify its content. If you are trying to change its content, then with those changes a new object will be created.
      Here c and d pointing to the same object. You are trying to change its content using the reference d. Therefor a new object will be created and d now pointing to the newly created object. But c pointing to the old object only.

        If you try to print d then you will get ‘HiHimanshu’.
        Also you can try using “is” operator. is operator returns true if and only if two references share the same object.
        print(c is d) will give you False. Because c and d now pointing to different objects.
