Django3- Loops

This video tutorial covers the basics of loops in Python, focusing on for loops and while loops. It explains how to use for loops with lists and ranges to iterate over elements or repeat code a specific number of times. The tutorial also introduces while loops, demonstrating how they work with boolean conditions to execute code repeatedly until a condition is no longer met. Practical examples are provided to illustrate these concepts, highlighting the importance of loops in programming.

What is the primary use of a for loop when working with lists in Python?

• To iterate over each element in the list

• To sort the list

• To reverse the list

• To find the maximum value in the list

How can you iterate a specific number of times using a for loop in Python?

• By using a dictionary

• By using a list

• By using the range function

• By using a while loop

What does the range function return when given the parameters (1, 10)?

• Numbers from 1 to 9

• Numbers from 1 to 10

• Numbers from 0 to 9

• Numbers from 0 to 10

Why might a while loop run indefinitely?

• Because it lacks a condition

• Because it has a syntax error

• Because the condition never becomes false

• Because it is used incorrectly with a list

What is a common use case for while loops in programming?

• To perform an action while a condition is true

• To sort a list

• To iterate over a fixed list

• To find the maximum value in a list

What is the shorthand way to increment a variable by 1 in Python?

• variable += 1

• variable = variable + 1

• increment(variable)

• variable++

In a while loop, what happens when the condition is no longer true?

• The loop throws an error

• The loop terminates

• The loop restarts

• The loop continues indefinitely
