8 practical cases of Python e-commerce API data and data science library (with code)

Python data science

With Python as the core language, it specializes in the field of "data science". The articles cover data analysis, data mining, machine learning and other dry goods, share a large number of data mining practical project analysis and explanation, and massive learning resources.

In order for everyone to have a preliminary understanding of the Python libraries commonly used in artificial intelligence, so as to choose a library that can meet their needs for learning, a brief and comprehensive introduction to the more common artificial intelligence libraries is given.

1、Numpy

NumPy(Numerical Python)It is  Pythonan extended program library that supports a large number of dimensional arrays and matrix operations. In addition, it also provides a large number of mathematical function libraries for array operations. The Numpyunderlying use is C语言written. Objects are directly stored in the array instead of object pointers, so its operation efficiency is much higher. Yu 纯Python代code. 纯PythonWe can compare the speed with the calculation of the sin value of the list in the example Numpy库:

import numpy as np
import math
import random
import time

start = time.time()
for i in range(10):
    list_1 = list(range(1,10000))
    for j in range(len(list_1)):
        list_1[j] = math.sin(list_1[j])
print("使用纯Python用时{}s".format(time.time()-start))

start = time.time()
for i in range(10):
    list_1 = np.array(np.arange(1,10000))
    list_1 = np.sin(list_1)
print("使用Numpy用时{}s".format(time.time()-start))

From the following running results, you can see that using  Numpy the library is faster than code written in pure Python:

0.017444372177124023s using pure Python and 
0.001619577407836914s using Numpy

3、OpenCV

OpenCV is a cross-platform computer vision library that can run on Linux, Windows and Mac OS operating systems. It's lightweight and efficient—consisting of a series of C functions and a handful of C++ classes, it also provides  Python interfaces that implement many common algorithms in image processing and computer vision. The following code tries to use some simple filters, including image smoothing, Gaussian blur, etc.:

import numpy as np
import cv2 as cv
from matplotlib import pyplot as plt
img = cv.imread('h89817032p0.png')
kernel = np.ones((5,5),np.float32)/25
dst = cv.filter2D(img,-1,kernel)
blur_1 = cv.GaussianBlur(img,(5,5),0)
blur_2 = cv.bilateralFilter(img,9,75,75)
plt.figure(figsize=(10,10))
plt.subplot(221),plt.imshow(img[:,:,::-1]),plt.title('Original')
plt.xticks([]), plt.yticks([])
plt.subplot(222),plt.imshow(dst[:,:,::-1]),plt.title('Averaging')
plt.xticks([]), plt.yticks([])
plt.subplot(223),plt.imshow(blur_1[:,:,::-1]),plt.title('Gaussian')
plt.xticks([]), plt.yticks([])
plt.subplot(224),plt.imshow(blur_1[:,:,::-1]),plt.title('Bilateral')
plt.xticks([]), plt.yticks([])
plt.show()
