x = 2
x = x * 3
x = x + 1
print(x)

a) 5
b) 7
c) 8
d) 9

Correct answer is d)
Explanation: The code multiplies the value of “x” by 3, adds 1 to it, and assigns the result back to “x”. Therefore, the value of “x” becomes 7, then 8.

22). What will be the value of the variable “y” after the execution of the following code?
x = [1, 2, 3]

Explanation: The round() function in Python rounds a number to the nearest whole number. In this case, num is 2.789, which is closer to 3 than to 2. Therefore, when you use round(num), it will round up to 3.0.

11). Python Variable must be declared before it is assigned a value:

a) True
b) False

Correct answer is b).
Explanation: No need to declare a variable before it is assigned a value

12). What are the things inside the list called?
a) variables
b) identifiers
c) elements
d) items

Correct answer is c).
Explanation: The things inside the list are called elements.

13). Identify the correct key value pair:
dict = {“Name”:”Rahul”, “Age”:24, “Occupation”:”Lawyer”}
a) Key is Rahul, Value is Name
b) Key is Name, Value is 24
c) Key is Name, Value is Rahul
d) Key is Name, Value is Age

Correct answer is c).
Explanation: Here, we are asked to identify the correct key value PAIR, so it will be option c).

14). Choose the correct option of the below code:

def num():
global a
a = 20
a = a+10
print(a)

a=10
num()
print(a)

a) 30
10

b) 30
30

c) 20
10

d) 20
20

Correct answer is b).
Explanation: Inside function num(), variable “a” is initially declared as global and assigned value as 20. Value of “a” will be printed when num() is called.
Variable inside the function will be given preference and hence the output of a will be a = a+10 = 20+10 = 30.
As we have declared “a” as global so when the function ends, outside print(a) will also output 30. So the correct answer is b).

15). What will be the output of the following code:
print(20//7)
a) 2
b) 2.0
c) 2.857142857142857

list1 = [1,2,3,4]
tup1 = tuple(list1)
print(tup1)
a) [1,2,3,4]
b) (1,2,3,4)
c) 1 2 3 4
d) The code will give an error while running

Correct answer is b).
Explanation: In this code, we are converting a list into a tuple and then printing it, so the output that we will get will be in tuple format.

1. Python Variable Tutorial: A Comprehensive Guide

Python Variable:

Introduction:
Variables are an important concept in any programming language, including Python. In simple language, a variable is a named location in memory that stores a value. In Python, you can use variables to store any type of data, including numbers, strings, and even complex data structures like lists and dictionaries.

Creating Variables in Python:

To create a variable in Python, you need to give it a name and assign a value to it. Here’s an example:
Name = “ Omkar “
Age = 25
Profession = “Software Engineer “
In the example above, we created three variables: Name, Age, and Profession.
The name variable is a string.
The age variable is an integer.
The Profession variable is also a string.

Python Variable Naming Rules:

When creating variables in Python, there are a few rules that you need to follow:
1. Variable names must start with a letter or underscore (_), followed by any combination of letters, digits, and underscores.
2. Variable names are case-sensitive, which means name and Name are two different variables.
3. A variable name cannot start with a number.
4. A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ).

Python Variable Types:

Python Variable types:
1. Numbers – Consists of integers, floating-point numbers, and complex numbers.
2. Strings – Consists of characters in quotes.
3. Booleans – Consists of True or False values.
4. Lists – Consists of ordered sequences of elements.
5. Tuples – Consists of ordered, immutable sequences of elements.
6. Sets – Consists of unordered collections of unique elements.
7. Dictionaries – Consists of unordered collections of key-value pairs.

Checking types of the variable:
First, we will create some Python variable.
Name = “ Omkar “
Age = 25
Height = 5.8 ft

To check the type of the variable use the type() function.
print(type(Name)) #Output: <class ‘str’>
print(type(Age)) #Output: <class ‘int’>
print(type(Height)) #Output: <class ‘float’>

Python variable assignment types:

Value Assignment:

To assign the value to a Python variable use equal sign ( = ).
Example:
A = 10
We can also assign the same value to multiple Python variables.
A = B = C = 10

Multiple value assignment:

We can assign different values to different Python variables at the same time. We separate the variables and their values by ‘ , ‘.
Example:
a, b, c = 40, 50, 60
Here,
Value of variable a is 40 , b is 50 and c is 60.

Python Variable scope:

Scope of Variable:

In Python, the scope of a variable determines where in the code the variable can be accessed and used. The scope of a variable is defined by where the variable is created and assigned a value.
There are two types of Python variable scopes: global scope and local scope.

1. Global Scope: Variables created outside of any function or class have a global scope. This means that they can be accessed and modified from anywhere in the code, including within functions and classes.
Example:
number = 100 # global Python variable

def print_number():
print(number) # accessing global variable

def modify_number():
global number # declaring number as global variable
number = 200 # modifying global variable

print_number() # Output: 100
modify_number()
print_number() # Output: 200
In the example above, the variable number is declared outside of any function, so it has a global scope. The function print_number() can access and print the value of the number, and the function modify_number() can modify the value of the number by declaring it as a global variable using the global keyword.

2. Local Scope: Variables created inside a function or class have a local scope. This means that they can only be accessed and modified within that function or class.
Example:
def my_function():
number = 100 # local Python variable
print(number) # accessing local variable

my_function() # Output: 100
print(number) # NameError: name ‘number’ is not defined

Basic Mathematical operations using variables:

Creating variables and assigning value to them:
a, b = 10 , 20

Performing operations and printing output:
print(a+b) #Output: 30
print(a-b) #Output: -10
print(a*b) #Output: 200
print(a/b) #Output: 0.5

Variables are an important concept in Python programming language. They allow you to store and manipulate data in your code and are important for writing effective programs. By understanding how to create, name, and use variables, you can write Python code that is easy to read and maintain.
