Welcome to the world of “Code Golfing,” where programmers compete to achieve the shortest possible solution to a given problem.
Code golfing is not just about reducing the number of characters; it’s an art that demands creativity, cunning, and a deep understanding of the language’s quirks.
On my Twitter and Instagram accounts, I frequently share my programming journey and development experiences.
In this article, we will explore the techniques and tricks of code golfing in Python.
Ternary Operators
Utilize the ternary operator (conditional expression) to shorten simple if-else constructs. For example:
# Traditional if-else result = x if condition else y # Code golfing version result = condition and x or y
Chaining Comparison Operators
You can chain comparison operators to perform multiple comparisons in a single line. For example:
# Traditional comparison if x > 10 and x < 20: # Code golfing version if 10 < x < 20:
List Comprehensions
Use list comprehensions to generate lists succinctly without the need for explicit loops. For example:
# Traditional loop
squares = []
for x in range(10):
squares.append(x**2)
# Code golfing version
squares = [x**2 for x in range(10)]
Lambdas and map()
Combine lambda functions with map() to apply a simple operation to all elements in a list
