Python List vs NumPy Array: What's the difference?
Both are useful, but they serve different purposes.
Python Lists
Can store different data types
Use loops or comprehensions for element-wise calculations
Flexible and suitable for general-purpose programming
NumPy Arrays
Usually store elements of the same data type
Support fast vectorized mathematical operations
Often use less memory for numerical data
Ideal for data analysis and scientific computing
Example:
nums = [1, 2, 3]
print([x * 2 for x in nums])
# [2, 4, 6]
With NumPy:
import numpy as np
arr = np.array([1, 2, 3])
print(arr * 2)
# [2 4 6]
Notice the difference? NumPy lets you perform element-wise calculations directly, without writing an explicit loop.
Which one do you use more often: Python Lists or NumPy Arrays?

Key concepts to remember:
def — Defines a function.
function_name — The name of the function.
parameters — Inputs accepted by the function.
return — Sends a result back to the caller.
function_name() — Calls the function.
