Python Condition Controlled Iteration

What is the syntax for a while loop in Python?

• for <condition>:

• while <condition>:

• do while <condition>:

• if <condition>:

How is the condition for a while loop evaluated in Python?

• The condition for a while loop in Python is evaluated before each iteration.

• The condition for a while loop in Python is evaluated only once at the beginning.

• The condition for a while loop in Python is not evaluated at all.

• The condition for a while loop in Python is evaluated after each iteration.

What is the purpose of the 'break' statement in a while loop?

• The purpose of the 'break' statement in a while loop is to restart the loop from the beginning.

• The purpose of the 'break' statement in a while loop is to execute the loop only once.

• The purpose of the 'break' statement in a while loop is to skip the next iteration of the loop.

• The purpose of the 'break' statement in a while loop is to exit the loop prematurely. But this is bad practice...

Explain the difference between 'while' and 'for' loops in Python.

• The 'while' loop is used for iterating over a sequence, while the 'for' loop is based on a condition.

• The 'while' loop is only used for strings, while the 'for' loop is used for numbers.

• The 'while' loop is based on a condition, while the 'for' loop is based on iterating over a sequence.

• The 'while' loop is used for counting, while the 'for' loop is based on iterating over a sequence.

What are the key concepts related to condition controlled iteration in Python?

• for loop

• switch statements

• do-while loop

• while loops

What are the advantages of using a while loop in Python?

• While loops cannot be used to iterate over a list or tuple

• While loops in Python are slower than for loops

• The advantages of using a while loop in Python include its flexibility in handling unknown number of iterations and its ability to create infinite loops if not properly controlled.

• While loops are not as readable as for loops

What are the disadvantages of using a while loop in Python?

• While loops in Python are not as efficient as for loops

• The main disadvantage of using a while loop in Python is the possibility of creating an infinite loop if the condition is not properly defined or updated within the loop.

• Using while loops can lead to code that is harder to read and understand

• While loops in Python are not suitable for iterating over lists or arrays

How does the 'continue' statement work in a while loop?

• The 'continue' statement in a while loop ends the loop and moves to the next iteration

• The 'continue' statement in a while loop executes the remaining code in the current iteration and then moves to the next iteration

• The 'continue' statement in a while loop skips the remaining code in the current iteration and moves to the next iteration.

• The 'continue' statement in a while loop only works in for loops, not while loops

Explain the concept of 'infinite loop' in the context of while loops in Python.

• An infinite loop in the context of while loops in Python occurs when the condition of the loop always remains True, causing the loop to run indefinitely without stopping.

• An infinite loop in Python occurs when the loop runs for a very long time

• Infinite loops occur when the loop condition is False

• Infinite loops are caused by using the wrong syntax in while loops

What are the potential applications of condition controlled iteration in Python?

• Performing mathematical calculations

• Implementing game loops, processing user input, and iterating through data structures

• Handling file input/output

• Creating graphical user interfaces
