๐Ÿ Python Pro Tips That I Wish I Use More...

As a Python enthusiast, I'm always on the lookout for ways to write cleaner, more efficient code. Here are some of my favorite Python tricks that can help you become a more effective programmer:

  1. List Comprehensions: Create lists with concise, readable one-liners.
even_numbers = [x for x in range(10) if x % 2 == 0 and x != 0]
Enter fullscreen mode Exit fullscreen mode
  1. F-strings: Format strings easily and readably (Python 3.6+).
name, age = "John", 30
print(f"I'm {name} and I'm {age} years old.")
Enter fullscreen mode Exit fullscreen mode
  1. Enumerate: Get both index and value when iterating.
for index, value in enumerate(["a", "b", "c"]):
    print(f"Index: {index}, Value: {value}")
Enter fullscreen mode Exit fullscreen mode
  1. Unpacking: Assign multiple variables in one line.
a, b, c = 1, 2, 3
Enter fullscreen mode Exit fullscreen mode
  1. Slicing: Manipulate sequences efficiently.
my_list = [0, 1, 2, 3, 4, 5]
reversed_list = my_list[::-1]
Enter fullscreen mode Exit fullscreen mode
  1. Use Counter: use collections.Counter for counting elements.
from collections import Counter
my_list = [1, 1, 2, 3, 3, 3, 4]
print(Counter(my_list))
Enter fullscreen mode Exit fullscreen mode
  1. Flattening: Flatten nested lists with itertools.chain.
import itertools
nested_list = [[1, 2], [3, 4], [5, 6]]
flat_list = list(itertools.chain.from_iterable(nested_list))
Enter fullscreen mode Exit fullscreen mode
  1. Iterate Over Many: Use zip() to iterate over multiple lists simultaneously.
names = ["Alice", "Bob", "Charlie"]
ages = [25, 30, 35]
for name, age in zip(names, ages):
    print(f"{name} is {age} years old")
Enter fullscreen mode Exit fullscreen mode
