FAQ

Q: What is Python?

A: Python is an object-oriented interpreted high-level programming language known for its popularity in data science.

Q: How do you download and install Python?

A: Python can be downloaded and installed by following a step-by-step guide from the official Python website.

Q: What is PyCharm IDE?

A: PyCharm IDE is an integrated development environment used for Python programming.

Q: Explain the concept of local and global scopes in Python.

A: Local scope refers to the visibility of variables limited to a specific function, while global scope variables are accessible throughout the entire program.

Q: How do you utilize global variables in Python?

A: Global variables in Python can be used by declaring them outside any function and then referencing them within functions as needed.

Q: What are decision-making statements in Python?

A: Decision-making statements in Python include if, if-else, and if-elif-else, which determine the flow of execution based on certain conditions.

Q: What is the purpose of the break statement in Python loops?

A: The break statement is used in loops to immediately terminate execution and exit the loop.

Q: How is user input obtained in Python?

A: User input in Python is obtained using built-in methods like input(), allowing users to enter values during program execution.

Q: What are Lambda functions in Python?

A: Lambda functions are anonymous functions defined using the lambda keyword without a function name, commonly used for small tasks and one-liners.

Q: Explain the concept of recursion in Python.

A: Recursion in Python involves a function calling itself either directly or indirectly, often used for tasks that can be broken down into simpler sub-problems.
