What is the difference between a variable and a data type in Python?

• A variable is a type of value, while a data type is a name that refers to a value.

• A variable can hold multiple values, while a data type can only hold one value.

• A variable is used for calculations, while a data type is used for storing values.

• A variable is a name that refers to a value, while a data type is the type of value that a variable can hold.

Explain the concept of dynamic typing in Python.

• Dynamic typing in Python refers to the process of assigning a type to a variable during compilation.

• The type of a variable is fixed and cannot be changed in Python.

• Dynamic typing in Python means that variables must be declared with a specific data type.

• The type of a variable is interpreted at runtime, not during compilation.

What are the different data types available in Python?

• int, float, char, string, array, tuple, set, map, boolean, and void

• int, float, complex, str, list, tuple, set, dict, bool, and NoneType

• integer, float, complex, string, array, tuple, set, dictionary, boolean, and null

• int, float, double, str, list, tuple, set, dict, bool, and NoneType

How do you declare a variable in Python?

• variable_name = value

• variable = name_value

• name = variable_value

• value = variable_name

What is the syntax for an if statement in Python?

• if [condition]

• if {condition}

• if condition:

• if (condition)

What is the purpose of the else statement in Python?

• To define a block of code that will be executed if the condition in the if statement is false.

• To define a block of code that will be executed regardless of the condition in the if statement.

• To skip the execution of the if statement and move to the next block of code.

• To define a block of code that will be executed if the condition in the if statement is true.

How do you use the elif statement in Python?

• To repeat the if statement

• To check for a single condition

• To end the program

• To check for multiple conditions after an initial if statement.

What is the difference between a while loop and a for loop in Python?

• A while loop is used for iterating over a range of values, while a for loop is used for checking conditions.

• A while loop is used when the number of iterations is not known beforehand, while a for loop is used when the number of iterations is known.

• A while loop is used for executing a block of code a specific number of times, while a for loop is used for executing code indefinitely.

• A while loop is used for string manipulation, while a for loop is used for mathematical operations.

Explain the concept of range() function in Python.

• The range() function in Python is used to generate a sequence of numbers.

• The range() function in Python is used to find the maximum value in a sequence of numbers.

• The range() function in Python is used to reverse a sequence of numbers.

• The range() function in Python is used to calculate the average of a sequence of numbers.

How do you use the break statement in a loop in Python?

• You use the break statement in a loop in Python to continue to the next iteration

• You use the break statement in a loop in Python to exit the loop prematurely.

• The break statement in a loop in Python is used to print the loop index

• The break statement in a loop in Python is used to add an element to the loop
