In Python, loops are control structures that allow you to repeatedly execute a block of code based on a certain condition.
Types of loops
There are two main types of loops in Python: for loops and while loops.
1. for Loop:
The for loop is used to iterate over a sequence (such as a list, tuple, string, or range) and execute a block of code for each item in the sequence.
# Example of a for loop
fruits = ["apple", "banana", "orange"]
for fruit in fruits:
print(f"Current fruit: {fruit}")
Output:
Current fruit: apple
Current fruit: banana
Current fruit: orange
2. while Loop:
The while loop repeatedly executes a block of code as long as a specified condition is true.
# Example of a while loop
counter = 0
while counter < 5:
print(f"Current count: {counter}")
counter += 1
Output:
Current count: 0
Current count: 1
Current count: 2
Current count: 3
Current count: 4
In this example, the while loop continues to execute as long as the condition counter < 5 is true.
Loops are essential for automating repetitive tasks, iterating over data structures, and implementing various algorithms. They provide a way to execute a set of instructions multiple times, making your code more efficient and concise.
