Final answer:
A control structure in Python that repeatedly executes code until a condition becomes false is a while loop. It runs as long as the condition is true and stops when it is no longer satisfied.
Step-by-step explanation:
The control structure in Python that executes the same lines of code multiple times until a starting condition becomes false is known as a while loop. Using this loop, you can execute a set of statements as long as a condition is true. Once the condition becomes false, the loop stops executing and the program moves on to the next block of code. Here's a simple example:
counter = 0
while counter < 5:
print(counter)
counter += 1
In this example, the while loop will continue to execute as long as the variable counter is less than 5. Each iteration increases counter by 1, and once it reaches 5, the loop terminates.
