Can you explain what is meant by 'cycle' in programming?

In programming, a loop is a construct that allows repeating a block of code multiple times while a certain condition is true. Loops are used to automate repetitive tasks, such as iterating over list elements or performing operations a specified number of times.

In Python, there are several types of loops:

• for — iterates over elements of a sequence (lists, strings, ranges, etc.).
• while — executes code as long as the condition is true.

Example of a for loop:

for i in range(5):
    print(i)

This code will output numbers from 0 to 4.

Example of a while loop:

count = 0
while count < 5:
    print(count)
    count += 1

Loops help avoid code duplication and make programs more concise and understandable.
