Complete Python Scripting for Automation - Introduction to while loop

What is the primary difference between a for loop and a while loop in Python?

• A for loop is used for infinite iterations.

• A while loop cannot be used with strings.

• A while loop requires a condition to be true to execute.

• A for loop can only iterate over numbers.

How can you create an infinite loop using a while loop?

• By using a for loop with a large range.

• By setting the condition to false.

• By using 'while True'.

• By using a break statement.

What is a practical use of an infinite while loop?

• To monitor a file system continuously.

• To execute a block of code only once.

• To print a message once.

• To iterate over a list of numbers.

When would you use a while loop with a condition?

• When the number of iterations is unknown but depends on a condition.

• When you want to iterate over a fixed list.

• When you want to execute code only once.

• When you know the exact number of iterations.

How can you stop a while loop based on a condition?

• By using a break statement when the condition is met.

• By setting the loop condition to false initially.

• By using a for loop instead.

• By using a continue statement.

What is the role of a counter in a while loop?

• To keep track of the number of iterations.

• To stop the loop immediately.

• To execute the loop infinitely.

• To decrease the number of iterations.

How does a while loop determine when to stop iterating?

• It stops when a continue statement is used.

• It stops after a fixed number of iterations.

• It stops when the condition becomes false.

• It stops when a break statement is used.

What is a key advantage of using a while loop?

• It can only iterate over numbers.

• It allows for dynamic iteration based on conditions.

• It can only be used for infinite loops.

• It is faster than a for loop.

Which scenario is best suited for a while loop?

• When the loop needs to run until a condition changes.

• When iterating over a fixed list.

• When the number of iterations is predetermined.

• When executing a block of code once.

What should you do if you want a while loop to execute a block of code a specific number of times?

• Use a for loop instead.

• Use a counter to control the number of iterations.

• Set the condition to false initially.

• Use a break statement immediately.
