else statement can also be used with loops, such as
while loops, to execute a block of code after the loop has completed its iterations without any
break statements being encountered.
for i in range(5): print(i) else: print("Loop completed without encountering a break statement")
In this case, the
else block will be executed only if the loop completes all its iterations without any early termination using the
else block is optional, and you can use it according to your specific programming needs.
Python for else example
Here are a few more examples of how the
else statement is used in Python:
Checking Prime Numbers
num = 17 if num > 1: for i in range(2, num): if num % i == 0: print(num, "is not a prime number") break else: print(num, "is a prime number") else: print(num, "is not a prime number")
In this example, we’re checking if a given
num is a prime number. The
else block is used with the
for loop to print whether the number is prime or not after completing all iterations.
Handling User Input
username = input("Enter your username: ") if username == "admin": print("Welcome, admin!") else: print("Welcome,", username)
This program asks the user for their username and uses the
else block to provide a customized welcome message based on the input.
num = 28 factors =  for i in range(1, num + 1): if num % i == 0: factors.append(i) print("Factors of", num, "are:", factors)
else block is not used, but this example shows how you might find factors of a number and create a list of those factors.
else with a
count = 0 while count < 5: print("Count:", count) count += 1 else: print("Loop completed")
In this example, the
else block is executed when the
while loop completes all iterations without any
These examples should help you understand how the
else statement is used in various contexts in Python to handle different scenarios.
