帖子 Python List vs NumPy Array: What's the difference?

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?
