1.  What is the difference between = and == operators?

a=10

b=20

=	==
a=b	a==b
i.e: we are assigning the value of variable ‘b’ to the left hand side variable ‘a’	We comparing two variables, which returns Boolean True/False
print(a)	print(a==b) or print(b==a) # compares, we get result True or false
Output: 20	Output: True

2. Find out the output of the following program

a=10

b=10

print(a is b)

x=True

y=True

print(x is y)

output:

True

True

3.  “Python is my favorite Programming language”

How to find the “favorite” is existing or not in the string?

Ans:

>>> a="Python is my favorite Programming language"

>>> print("favorite" in a)

True

>>>

4. If a=20, b=30

(a) Convert from decimal to binary (b) find the a&b (c) a|b

Ans:

(a)  a=10100, b=11110

(b)  a&b=20

(c)  a|b=30

(5.) Find out the a=25, (i) calculate a>>2 (ii) calculate a>>3

Ans:

a=11001

a>>2

6

>>> a>>3

3

(6.) Evaluate the expression: 3/2*4+3+(10//4)**3-2

Ans: 15.0

(7.) What is split() function?

Ans:

The split() method splits a string into a list.

You can specify the separator, the default separator is any whitespace.

Example:

"2 4".split() #We have to call the split() function w.r.t string

['2', '4']

>>> "1, 2 3 Hyd, Vij Kurnul,Kadapa atp".split(',')

['1', ' 2 3 Hyd', ' Vij Kurnul', 'Kadapa atp']

>>> 

(8.) Find out the output

a = 21

b = 10

c = 0

c = a + b

print ("c = a + b is ", c)

c += a

print ("c += a is", c )

c *= a

print ("c *= a is", c )

c /= a

print ("c /= a is ", c )

c  = 2

c %= a

print ("c %= a is", c)

c **= a

print ("c **= a is", c)

c //= a

print ("c //= a is", c)

Ans:

When you execute the above program, it produces the following result −

output:

c = a + b is  31

c += a is 52

c *= a is 1092

c /= a is  52.0

c %= a is 2

c **= a is 2097152

c //= a is 99864

9.  List out the bit wise operators in python.

Operator	Name	Description
&	AND	Sets each bit to 1 if both bits are 1
|	OR	Sets each bit to 1 if one of two bits is 1
^	XOR	Sets each bit to 1 if only one of two bits is 1
~	NOT	Inverts all the bits
<<	Zero fill left shift	Shift left by pushing zeros in from the right and let the leftmost bits fall off
>>	Signed right shift	Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off

 10. Convert this string to lowercase? (PYTHON)

Ans:  string='PYTHON'

                         print(string.lower())
