🚀 10 Simple Ways to Speed Up Your Python Code

Python is great, but sometimes it can be slow—especially with large datasets, loops, and computational tasks. Want to boost performance and make your code run faster?
Here are 3 quick hacks (out of 10!) to get you started:
âś… Use Generators Instead of Lists

def squares_generator(data):
    for elem in data:
        yield elem * 2

Enter fullscreen mode Exit fullscreen mode

🔥 Why? Saves memory by generating values on demand instead of storing them all at once.
âś… Leverage map() and filter() Instead of Loops

numbers = [1, 2, 3, 4]
squares = map(lambda x: x**2, numbers)  
print(list(squares))  # [1, 4, 9, 16]

Enter fullscreen mode Exit fullscreen mode

🔥 Why? Faster than for loops since these functions optimize performance under the hood.
âś… Cache Results with lru_cache

from functools import lru_cache  

@lru_cache(maxsize=None)  
def slow_function(n):  
    return sum(range(n))  

Enter fullscreen mode Exit fullscreen mode

🔥 Why? Saves previous results to avoid redundant calculations.
But that’s just the beginning…
