Ace Your Python Interview: Common Questions and How to Answer Them Part-5

 

Here are a few more Python interview questions and sample answers:

6. What is the difference between 'continue' and 'break' statements in Python?

Answer: Both 'continue' and 'break' statements are used to modify the flow of control in loops. However, 'continue' is used to skip the current iteration of a loop and move to the next one, while 'break' is used to terminate the loop entirely.

7. How do you handle errors and exceptions in Python?

Answer: In Python, errors and exceptions can be handled using try-except blocks. A try block is used to enclose the code that might cause an exception, while an except block is used to handle the exception if it occurs. Here's an example:

python
try:
    # Code that might raise an exception
except ExceptionType:
    # Code to handle the exception

8. What is the difference between local and global variables in Python?

Answer: Local variables are those that are defined inside a function and can only be accessed within that function. Global variables, on the other hand, are defined outside of any function and can be accessed from any part of the code.

9. How do you import modules in Python?

Answer: Modules can be imported in Python using the 'import' statement. Here's an example:

python
import math

# Now we can use the math module's functions and constants
print(math.pi)

10. What is the difference between Python 2 and Python 3?

Answer: Python 2 and Python 3 are different versions of the Python programming language. The main differences between the two are related to syntax and backwards compatibility. Python 3 is designed to be more consistent and explicit than Python 2, and it includes several new features and libraries. However, some older Python 2 code may not work in Python 3 without modifications.

11. What are some common libraries used in Python?

Answer: Python has a wide range of third-party libraries that can be used to extend its functionality. Some common libraries include NumPy (for numerical computing), Pandas (for data analysis), Matplotlib (for data visualization), and TensorFlow (for machine learning).

12. What is the difference between a shallow copy and a deep copy in Python?

Answer: A shallow copy creates a new object that references the original object's memory location, while a deep copy creates a new object with its own memory location that is a copy of the original object's data. A shallow copy only copies the top-level object, while a deep copy recursively copies all nested objects.

I hope these additional questions and answers are helpful! Remember to practice and review common Python interview questions before your interview to increase your chances of success.
