Common Interview Questions
1. What are the key features of Python?
Python offers simplicity and ease of learning, making it accessible to beginners. It supports procedural, object-oriented, and functional programming paradigms. Developers can use Python across different platforms because of its platform independence. Its extensive libraries enable tasks such as data analysis, web development, and machine learning. The open-source nature and active community enhance its usability and popularity.
Company: TCS, Infosys
2. What is the difference between Python 2 and Python 3?
Python 3 introduces features designed for modern programming, unlike Python 2, which is outdated and unsupported. By default, Python 3 handles Unicode, while Python 2 relies on ASCII encoding. The syntax in Python 3 requires functions like print("text"), whereas Python 2 uses print "text". Developers prefer Python 3 for new projects due to its updated capabilities.
Company: Wipro, Capgemini
3. How do you write a comment in Python
To write a comment in Python, start the line with the # symbol. Python’s interpreter ignores everything after the # on the same line. For example: # This is a comment. Comments help developers explain code and improve readability.

4. What are Python’s data types?
Python provides various data types for handling information. For numbers, it includes int, float, and complex. To work with text, developers use str. Sequences such as list, tuple, and range allow for ordered data. For unique items, the set type is available, and for key-value pairs, Python provides dict. The bool type represents true or false values, making Python adaptable for diverse applications.
Company: IBM, Accenture
5. How can you check the type of a variable in Python?
To check a variable’s type, use the type() function. For instance, if x = 10, calling type(x) shows <class 'int'>. This method allows developers to confirm the data type and perform operations accordingly.
Company: Microsoft, Google
