7 Little‑Known Python Tricks That Can Supercharge Your Code

Python is beloved for its readable syntax, but many handy tricks are often overlooked; this article shares seven useful techniques.

1. Function attributes – Functions can hold custom attributes just like objects. Example:

# FunctionAttributes
def func():
    pass
func.name = "HaiderImtiaz"
func.age = 22
func.Profession = "Pythondeveloper"
func()
print("Name:", func.name)
print("Age:", func.age)
print("Profession:", func.Profession)

2. Incomplete code placeholders – Use the pass statement as a placeholder in functions, classes, loops, or conditionals.

# Place Holders
def func():
    pass
class data:
    pass
for x in range(5):
    pass
if 2 == 4:
    pass
else:
    pass

3. eval() function – Evaluates a string as a Python expression.

# Eval example 1
x = 5
y = eval('x + 2')
print(y)  # 7
# Eval example 2
x = 2
y = eval('x ** 3')
print(y)  # 8

4. Start a simple HTTP server – Launch a file‑hosting server directly from the interpreter:

# Starting a Web server
python -m http.server 5000

Running this command displays the address http://0.0.0.0:5000/ where the server is listening.

5. Unlimited arguments – Use *args to accept any number of positional arguments.

# Unlimited Arguments
def func(*arg):
    print("Argument Passed:", len(arg))
func(1, 2, 4, 5, 6, 7)  # Argument Passed: 6

6. zip() method – Combine two iterables into tuples, useful for parallel iteration.

# Zip method
list1 = ["Python", "JavaScript", "C#", "Dart"]
list2 = ["Machine Learning", "Web Developer", "Software", "App Dev"]
for x, y in zip(list1, list2):
    print(x, y)
# Output:
# Python Machine Learning
# JavaScript Web Developer
# C# Software
# Dart App Dev

7. Rotating a list – Quickly rotate elements left or right.

# Rotating list
lst = [10, 20, 30, 40, 50]
# rotate left
lst = lst[1:] + [lst[0]]
print(lst)  # [20, 30, 40, 50, 10]
# rotate right
lst = [lst[-1]] + lst[:-1]
print(lst)  # [50, 10, 20, 30, 40]
