Loops are essential in programming for automating repetitive tasks. In Python, loops can be effectively used to process lists, allowing you to perform operations on each element in the list without writing repetitive code.
For Loop
The for loop is one of the simplest and most common ways to iterate over a list in Python. It allows you to execute a block of code for each item in the list. Here is an example:
# Define a list of fruitsfruits = ["apple", "banana", "cherry"]# Use a for loop to print each fruitfor fruit in fruits:print(fruit)Copied!âś•CopyIn this example, the loop iterates over each element in the fruits list and prints it. This method is straightforward and efficient for most list processing tasks.
While Loop
A while loop can also be used to iterate over a list. This loop continues to execute as long as a specified condition is true. Here is an example:
