Python For Else

Welcome to the fascinating world of Python programming! Today, let’s explore the ‘for-else’ loop, a cool feature that can make your code more powerful. Read this article to learn more about Python For Else.

However, Python’s ‘for‘ loop is excellent for that. Now, the ‘else‘ part adds a twist – it gets executed if your loop completes without any interruptions.

What is Else in For Loop?

The else keyword in the loop will denote the block of code that will run only when the loop is completed.

Example 1 for Else Keyword in Python

# Example: Checking if a number is prime

num = 11  # You can change this number to test different cases

for i in range(2, num):
    if num % i == 0:
        print(f"{num} is not a prime number.")
        break
else:
    print(f"{num} is a prime number.")

Output

11 is a prime number.

Important note: The else block cannot run the program, when the loop is either stopped by the break statement.

Example 2

# Example: Using break to exit a loop

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

for num in numbers:
    if num == 6:
        print(f"Loop is broken because num is {num}")
        break
    print(f"Processing {num}")

print("Loop finished.")

Output

Processing 1
Processing 2
Processing 3
Processing 4
Processing 5
Loop is broken because num is 6

Conclusion

To conclude, this article has listed Python for else keywords. Several examples are illustrated for a better understanding of the concept. Hence, Students can improve their skills and knowledge of Python for else keywords.
