else with loops

In Python, you can attach an else block to both for and while loops.

🔸 The else block runs only if the loop finishes normally (without hitting a break).

🔧 Syntax

for item in iterable:
    if condition:
        break  # If this happens, else will NOT run
else:
    # Runs only if loop wasn’t broken
    print("Completed without break!")

🔍 Why Use It?

• To know if a loop ran till the end without being interrupted

• No need for extra flags or conditions

• Cleaner code — especially useful in search tasks

💡 Real-Life Example: Searching a List

names = ["Alice", "Bob", "Charlie"]

for name in names:
    if name == "David":
        print("Found David!")
        break
else:
    print("David not found.")  # ✅ This runs only if David wasn't found

If David were in the list, the break would run and skip the else.

🔁 Works with while Loop Too

x = 0
while x < 5:
    if x == 6:
        break
    x += 1
else:
    print("Exited without break")  # ✅ This runs because break never happened

🧠 Real-Life Analogy

You’re searching your house for your lost keys:

• Found them in the 3rd room? → You stop searching (break), no celebration (else skipped).

• Checked all rooms, still no keys? → You sigh and say “Well, not here.” (else runs)
