10 Elegant Python Tricks to Write Cleaner Code

Assigning Multiple Variables

Conventional method assigns each variable separately, while the elegant method uses tuple unpacking:

a, b, c = 0, 1, 2

Sequence Unpacking

Instead of indexing each element, unpack the list directly:

info = ['brucepk', 'man', 'python']
name, sex, tech = info
print(name, sex, tech)

Elegant Conditional Assignment

Use a ternary expression to assign based on a condition:

x = -6
y = -x if x < 0 else x
print(y)

Chained Comparisons

Replace two separate comparisons with a chained comparison:

score = 82
if 80 <= score < 90:
    level = 'B'
    print(level)

Membership Test with in

Use in to check if a value belongs to a set:

num = 1
if num in (1, 3, 5):
    type = 'odd'
    print(type)

Truthiness Check

Leverage Python's truthiness to test for non‑empty containers without len():

A, B, C = [1, 3, 5], {}, ''
if A:
    print('A is non‑empty')
if B:
    print('B is non‑empty')
if C:
    print('C is non‑empty')

Any vs. Multiple or

Use any() to simplify multiple or conditions:

math, English, computer = 90, 59, 88
if any([math < 60, English < 60, computer < 60]):
    print('not pass')

All vs. Multiple and

Use all() to ensure all conditions are true:

math, English, computer = 90, 80, 88
if all([math > 60, English > 60, computer > 60]):
    print('pass')

Enumerating with Index

Replace manual index handling with enumerate():

L = ['math', 'English', 'computer', 'Physics']
for k, v in enumerate(L):
    print(k, ':', v)

List Comprehension

Generate a list of squares in a single line using a list comprehension: print([x*x for x in range(1, 6)]) Try these elegant patterns to write more readable Python code.
