Python Concepts

What are the different data types available in Python?

• array

• double

• char

• int, float, str, bool, list, tuple, set, dict

Explain the if-else control structure in Python with an example.

• Example: x = 5 if x > 5: print('x is greater than 5') else: print('x is less than or equal to 5')

• Example: x = 10 if x > 5: print('x is greater than 5')

• Example: x = 10 if x < 5: print('x is less than 5') else: print('x is greater than or equal to 5')

• Example: x = 10 if x > 5: print('x is greater than 5') else: print('x is less than or equal to 5')

How do you define a function in Python?

• Use the 'function' keyword followed by the function name and parentheses containing parameters, then write the function body.

• Use the 'func' keyword followed by the function name and parentheses containing parameters, then write the function body.

• Use the 'define' keyword followed by the function name and parentheses containing parameters, then write the function body.

• Use the 'def' keyword followed by the function name and parentheses containing parameters, then write the function body.

What is a module in Python? Provide an example.

• A module in Python is a programming language.

• A module in Python is a built-in function.

• A module in Python is a type of data structure.

• A module in Python is a file containing Python code. It can define functions, classes, and variables. Modules are used to organize code into reusable units. An example of a module in Python is the 'math' module, which provides mathematical functions.

How can you read data from a file in Python?

• Use 'write' function to read the content

• Execute 'open' function without specifying the file path

• Open the file using 'open' function and read the content using appropriate methods like 'read', 'readline', or 'readlines'.

• Access the file directly without using any functions

What is the difference between a list and a tuple in Python?

• Lists are immutable, tuples are mutable.

• Lists and tuples have the same methods available for manipulation.

• Lists are mutable, tuples are immutable.

• Lists and tuples cannot store different data types.

Describe the for loop in Python.

• A for loop in Python is used to iterate over a sequence in reverse order

• A for loop in Python is used to iterate over a sequence (list, tuple, string, etc.) or other iterable objects. It consists of an initialization, condition, and increment/decrement expression. The loop continues until the condition is false.

• A for loop in Python can only iterate over integers

• A for loop in Python is only used for mathematical calculations

What is the purpose of the 'return' statement in a function?

• To skip a step in the function

• To print a message to the console

• To pause the function execution

• To specify the value that the function should output or return.

How can you import a module in Python?

• use module

• import math

• include module

• import module

Explain the concept of exception handling in Python.

• Exception handling in Python is a way to create new errors intentionally

• Exception handling in Python is a way to deal with runtime errors that may occur during program execution. It involves using try, except, else, and finally blocks to handle exceptions gracefully.

• Exception handling in Python involves using if-else statements only

• Exception handling in Python is not necessary for error management
