Common Python Data Analysis Mistakes: Side-by-Side Comparison of Key Methods
Sorting Operations
List Sorting
Python lists offer two distinct sorting approaches with different behaviors:
# sort() modifies the list in-place and returns None
numbers = [3, 1, 4, 1, 5]
result = numbers.sort()
print(result) # None
print(numbers) # [1, 1, 3, 4, 5]
# sorted() returns a new sorted list, leaving the original unchanged
numbers ...
