Python List Tips and Tricks

As a Data Engineer, Python is everybody's everyday tool, and lists are among the most powerful structures. Here are some essential Python list tips and tricks that I find can simplify your code and make it more efficient! ??

1? List Comprehensions: A concise way to create lists. Instead of writing loops, try:

squares = [x**2 for x in range(10)]  
# [0, 1, 4, 9, 16, ...]        

2? Filter Using Comprehensions: Combine filtering and list creation:

even_numbers = [x for x in range(20) if x % 2 == 0]  
# [0, 2, 4, ...]        

3? Flatten Nested Lists: Flatten lists in one line:

nested = [[1, 2, 3], [4, 5], [6, 7, 8]]
flat = [num for sublist in nested for num in sublist]  
# [1, 2, 3, 4, 5, 6, 7, 8]        

4? Zip and Unzip Lists: Pair up list elements easily:

list1 = [1, 2, 3]
list2 = ['a', 'b', 'c']
paired = list(zip(list1, list2))  
# [(1, 'a'), (2, 'b'), (3, 'c')]        

5? Remove Duplicates: Quickly clean up your list:

unique_list = list(set([1, 2, 2, 3, 4, 4, 5]))  
# [1, 2, 3, 4, 5]
