Answer :-

 

 
	 
 
	 
Statements
 
	 
Result Returned by Python Shell
 
 
 
	 
1.
 
	 
a = 18
 
	 
>>> a = 18
>>> a
18
 
 
 
	 
2.
 
	 
b = 7
 
	 
>>> b = 7
>>> b
7
 
 
 
	 
3.
 
	 
c = b + 11
 
	 
>>> c = b + 11
>>> c
18
 
 
 
	 
4.
 
	 
d = c - 11
 
	 
>>> d = c - 11
>>> d
7
 
 
 
	 
5.
 
	 
id (7)
 
	 
>>> id (7)
2058842171888
 
 
 
	 
6.
 
	 
id (18)
 
	 
>>> id (18)
2058842172240
 
 
 
	 
7.
 
	 
id (a)
 
	 
>>> id (a)
2058842172240
id of a (variable) and 18 (integer number) is same because their memory address is same.
 
 
 
	 
8.
 
	 
id (b)
 
	 
>>> id (b)
2058842171888
id of b (variable) and 7 (integer number) is same because their memory address is same.
 
 
 
	 
9.
 
	 
id (c)
 
	 
>>> id (c)
2058842172240
id of c (variable) and 18 (integer number) is same because their memory address is same.
 
 
 
	 
10.
 
	 
id(d)
 
	 
>>> id(d)
2058842171888
id of d (variable) and 7 (integer number) is same because their memory address is same.
 
 
 
	 
11.
 
	 
d = 25 - b
 
	 
>>> d = 25 - b
>>> d
18
 
 
 
	 
12.
 
	 
id(d)
 
	 
>>> id(d)
2058842172240
Now id of d (variable) is changed because value of d (variable) is changed.
 
 
 
	 
13.
 
	 
string1 = 'Python'
 
	 
>>> string1 = 'Python'
>>> string1
'Python'
 
 
 
	 
14.
 
	 
string2 = string
 
	 
It will give error that is string is not defined.
 
 
 
	 
15.
 
	 
id (string1)
 
	 
>>> id (string1)
2058843177648
 
 
 
	 
16.
 
	 
id (string2)
 
	 
It will give error that is string2 is not defined.
 
 
 
	 
17.
 
	 
type (string1)
 
	 
>>> type (string1)
<class 'str'>
 
 
 
	 
18.
 
	 
type (string2)
 
	 
It will give error that is string2 is not defined.
 
 
 
	 
19.
 
	 
string3 = 'hello'
 
	 
>>> string3 = 'hello'
>>> string3
'hello'
 
 
 
	 
20.
 
	 
id (string3)
 
	 
>>> id (string3)
2058883254896
 
 
 
	 
21.
 
	 
num1 = 1 + 0j
 
	 
>>> num1 = 1 + 0j
>>> num1
(1+0j)
 
 
 
	 
22.
 
	 
num2 = 1
 
	 
>>> num2 = 1
>>> num2
1
 
 
 
	 
23.
 
	 
type(num1)
 
	 
>>> type(num1)
<class 'complex'>
 
 
 
	 
24.
 
	 
type(num2)
 
	 
>>> type(num2)
<class 'int'>
 
 
 
	 
25.
 
	 
id(num1)
 
	 
>>> id(num1)
2058882457488
 
 
 
	 
26.
 
	 
id(num2)
