🐍 9 Hidden Python Features You Didn’t Know Existed

Oct 30, 2025

1️⃣ else with Loops
Did you know a for or while loop can have an else?
It only runs if the loop finishes normally (no break) 👇

for i in range(3):
    print(i)
else:
    print(”Loop completed without break”)

✅ Output:

0  
1  
2  
Loop completed without break

💡 Great for search loops or validations.

2️⃣ _ for Last Result in REPL
Python automatically stores the last output in _ when you’re using the REPL.

5 + 7
_ + 3

✅ Output: 15
Perfect for quick math or testing without extra variables.

3️⃣ Multiple Assignment
Assign several variables in one line — elegant & Pythonic!

a, b, c = 1, 2, 3
print(a, b, c)

✅ Output: 1 2 3
💡 Makes your code cleaner and more readable.

4️⃣ zip() for Parallel Iteration
Loop over multiple lists at the same time!

names = [”Alice”, “Bob”]
ages = [25, 30]

for n, a in zip(names, ages):
    print(f”{n} is {a} years old”)

✅ Output:

Alice is 25 years old  
Bob is 30 years old

💡 Ideal for combining related data.

5️⃣ enumerate() to Track Index
No need to manage counters manually!

for i, val in enumerate([”a”, “b”, “c”], start=1):
    print(i, val)

✅ Output:

1 a  
2 b  
3 c

💡 Clean, readable, and beginner-friendly.

6️⃣ Underscore in Numeric Literals
Make large numbers human-friendly!

million = 1_000_000
print(million + 5000)

✅ Output: 1005000
💡 Same as 1000000, just easier to read.

7️⃣ Swap Variables Without a Temp Variable
No need for a third variable!

x, y = 5, 10
x, y = y, x
print(x, y)

✅ Output: 10 5
💡 One-liner elegance — pure Pythonic style.

8️⃣ else with Try/Except
The else block executes only if there’s no exception.

try:
    print(”No errors here”)
except:
    print(”Error occurred”)
else:
    print(”Else runs if no exception”)

✅ Output:

No errors here  
Else runs if no exception

💡 Great for separating error-free logic.

9️⃣ if __name__ == “__main__”:
Tells Python whether to run code or just import it!

def main():
    print(”Script running directly”)

if __name__ == “__main__”:
    main()

✅ Output:

Script running directly

💡 Helps make scripts both reusable and runnable.
