10 Python Secrets to Boost Productivity and Elegance in Your Code

Overview

Python is one of the most popular programming languages in the world. It is the top option for novice and seasoned developers due to its ease of use, readability, and extensive library ecosystem. Beyond the fundamentals, however, Python conceals a wealth of strong features that may shorten, speed up, and improve the elegance of your code.

In this blog, we will go through 10 Python tricks every developer should know. Whether you are new to Python or a seasoned coder, these will help you write smarter code.

Swapping Variables Without a Temporary Variable

In many languages, swapping values requires a temporary variable. But in Python, you can do it in one line:

a, b = 10, 20

a, b = b, a

print(a, b)  # Output: 20 10

a, b = 10, 20

a, b = b, a

print(a, b) # Output: 20 10

This is not only shorter but also more Pythonic.

Using List Comprehensions for Cleaner Loops

Instead of writing long for loops to build lists, use list comprehensions:

squares = [x**2 for x in range(10)]

print(squares) 

# Output: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

You can even add conditions:

even_squares = [x**2 for x in range(10) if x % 2 == 0]

print(even_squares) 

# Output: [0, 4, 16, 36, 64]

squares = [x**2 for x in range(10)]

print(squares)

# Output: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

You can even add conditions:

even_squares = [x**2 for x in range(10) if x % 2 == 0]

print(even_squares)

# Output: [0, 4, 16, 36, 64]

This makes your code concise and expressive.

Using Enumerate Instead of Range

When you need both index and value in a loop, use enumerate:

fruits = ["apple", "banana", "cherry"]

for index, fruit in enumerate(fruits, start=1):

    print(index, fruit)

Output:

1 apple

2 banana

3 cherry

fruits = ["apple", "banana", "cherry"]

for index, fruit in enumerate(fruits, start=1):

print(index, fruit)

Output:

1 apple

2 banana

3 cherry

It’s cleaner and avoids manual index management.

Dictionary Comprehensions

Just like list comprehensions, you can build dictionaries in one line:

numbers = [1, 2, 3, 4]

squares = {x: x**2 for x in numbers}

print(squares) 

# Output: {1: 1, 2: 4, 3: 9, 4: 16}

numbers = [1, 2, 3, 4]

squares = {x: x**2 for x in numbers}

print(squares)

# Output: {1: 1, 2: 4, 3: 9, 4: 16}

This is handy when transforming data.

Using the zip() Function

If you want to combine two lists into pairs, zip is your best friend:

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

scores = [85, 90, 95]

combined = dict(zip(names, scores))

print(combined) 

# Output: {'Alice': 85, 'Bob': 90, 'Charlie': 95}

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

scores = [85, 90, 95]

combined = dict(zip(names, scores))

print(combined)

# Output: {'Alice': 85, 'Bob': 90, 'Charlie': 95}

It’s especially useful when working with parallel lists.

Using *args and **kwargs

Python allows flexible function arguments with *args and **kwargs:

def greet(*args, **kwargs):

    for name in args:

        print("Hello", name)

    for key, value in kwargs.items():

        print(f"{key}: {value}")

 

greet("Alice", "Bob", age=25, city="London")

Output:

Hello Alice

Hello Bob

age: 25

city: London

def greet(*args, **kwargs):

for name in args:

print("Hello", name)

for key, value in kwargs.items():

print(f"{key}: {value}")

greet("Alice", "Bob", age=25, city="London")

Output:

Hello Alice

Hello Bob

age: 25

city: London

This is perfect for functions where you don’t know in advance how many arguments will be passed.

Using the get() Method for Dictionaries

Instead of checking if a key exists before accessing it, use get:

data = {"name": "Alice", "age": 25}

print(data.get("name"))       # Alice

print(data.get("city", "NA")) # NA

data = {"name": "Alice", "age": 25}

print(data.get("name")) # Alice

print(data.get("city", "NA")) # NA

This avoids KeyError and makes the code more robust.

String Formatting with f-Strings

Python’s f-strings (introduced in 3.6) are the cleanest way to format strings:

name = "Alice"

age = 25

print(f"My name is {name} and I am {age} years old.")

You can even do expressions inside:

print(f"Next year, I’ll be {age + 1}")

name = "Alice"

age = 25

print(f"My name is {name} and I am {age} years old.")

You can even do expressions inside:

print(f"Next year, I’ll be {age + 1}")

This is more readable than .format() or % formatting.

Using the any() and all() Functions

These built-ins make condition checks easy:

numbers = [2, 4, 6, 8]

print(all(n % 2 == 0 for n in numbers))  # True

print(any(n > 5 for n in numbers))       # True

numbers = [2, 4, 6, 8]

print(all(n % 2 == 0 for n in numbers)) # True

print(any(n > 5 for n in numbers)) # True

all() returns True if all conditions are met.
any() returns True if at least one condition is met.

Perfect for validation checks.

The Power of Slicing

Python’s slicing works not only on lists but also on strings and tuples:

text = "Python Tricks"

print(text[::-1])  # Reverse a string → skcirT nohtyP

Other examples:
nums = [1, 2, 3, 4, 5, 6]

print(nums[::2])&nbsp; # [1, 3, 5] → every second element

print(nums[1:4])&nbsp; # [2, 3, 4] → sublist

text = "Python Tricks"

print(text[::-1]) # Reverse a string → skcirT nohtyP

Other examples:

nums = [1, 2, 3, 4, 5, 6]

print(nums[::2])  # [1, 3, 5] → every second element

print(nums[1:4])  # [2, 3, 4] → sublist

This is a neat way to manipulate sequences.
