What is the difference between a variable and a constant in Python?

• Variables and constants are the same thing in Python

• Constants can be reassigned, while variables should not be changed

• Variables and constants cannot be used interchangeably in Python

• Variables can be reassigned, while constants should not be changed.

Explain the concept of data types in Python with examples.

• Data types in Python refer to the type of data that a variable cannot store.

• Data types in Python only include integer and float, other types are not supported.

• Data types in Python refer to the type of data that a variable can store. Examples of data types in Python include integer, float, string, boolean, and list.

• Examples of data types in Python include apple, banana, and orange.

How do you declare and initialize a string variable in Python?

• string = 'Hello, World!'

• my_string = 'Hello, World!'

• my_string = 12345

• my_string = Hello, World!

What are the different types of numerical data types in Python?

• char, double, and boolean

• int, float, and complex

• dict, tuple, and set

• str, bool, and list

Explain the concept of type conversion in Python with an example.

• Type conversion in Python refers to the process of converting one data type into another. This can be done using built-in functions like add(), subtract(), multiply(), etc.

• Type conversion in Python refers to the process of converting one data type into another. This can be done using built-in functions like str(), bool(), list(), etc.

• Type conversion in Python refers to the process of converting one data type into another. This can be done using built-in functions like input(), print(), range(), etc.

• Type conversion in Python refers to the process of converting one data type into another. This can be done using built-in functions like int(), float(), str(), etc. For example, converting a string to an integer using int() function: num_str = '10' int_num = int(num_str)

What is the syntax for an if-else statement in Python?

• if condition: # code to be executed if the condition is false else: # code to be executed if the condition is true

• if condition: # code to be executed if the condition is true else: # code to be executed if the condition is false

• if condition: # code to be executed if the condition is true else: # code to be executed if the condition is false

• if condition: # code to be executed if the condition is true else: # code to be executed if the condition is true

Give an example of using the if-else statement to check if a number is even or odd.

• if (num % 2 == 0): print('Odd') else: print('Even')

• if (num % 2 == 1): print('Even') else: print('Odd')

• if (num % 2 != 0): print('Even') else: print('Odd')

• if (num % 2 == 0): print('Even') else: print('Odd')

Explain the use of the elif statement in Python with an example.

• The elif statement is used to check for multiple conditions after an initial if statement.

• The elif statement is used to repeat the initial if statement.

• The elif statement is used to end the program if the initial if statement is false.

• The elif statement is used to check for conditions before the initial if statement.

What is the purpose of the else statement in Python?

• To define a new condition for the if statement.

• To execute a block of code when the condition of the if statement is true.

• To execute a block of code when the condition of the if statement is false.

• To skip the execution of the if statement block.

How do you nest if-else statements in Python? Provide an example.

• if x > 5: if y > 10: print('x is greater than 5 and y is greater than 10') else: print('x is not greater than 5')

• if x > 5: if y > 10: print('x is greater than 5 and y is greater than 10') else: print('x is greater than 5 but y is not greater than 10') else: print('x is not greater than 5')

• if x > 5: if y > 10: print('x is greater than 5 and y is greater than 10') else: print('x is greater than 5 but y is not greater than 10')

• if x > 5: if y > 10: print('x is greater than 5 and y is greater than 10') elif: print('x is not greater than 5')
