Q: 2. What are the types of loops available in Python?

Ans. Python has two types of loops: the 'for' loop and the 'while' loop. The 'for' loop is used to iterate over a sequence of elements, such as a list or a string. The 'while' loop is used to repeatedly execute a block of code as long as a condition is true.

Q: 3. How does the 'for' loop work in Python?

Ans. The 'for' loop in Python iterates over a sequence of elements and executes a block of code for each element in the sequence. It uses the 'in' keyword to specify the sequence and a variable to represent each element in the loop. The loop continues until all elements in the sequence have been processed.

Q: 4. How does the 'while' loop work in Python?

Ans. The 'while' loop in Python repeatedly executes a block of code as long as a certain condition is true. It first checks the condition, and if it is true, it executes the code block. After executing the code block, it checks the condition again and repeats the process until the condition becomes false.

FAQs on Quickly with Python - 04 - Loops Video Lecture - Python- Mastering Development in Python - Software Development
