Implementation of python batch reading of images and storing them in the database
这次给大家带来python批量读取图片且存入数据库的实现,python批量读取图片且存入数据库的注意事项有哪些,下面就是实战案例,一起来看一下。
本文实例讲述了Python实现批量读取图片并存入mongodb数据库的方法。分享给大家供大家参考,具体如下:
我的图片放在E:\image\中,然后使用python将图片读取然后,显示一张,存入取一张(可以注释掉显示图片的语句),通过Gridfs的方式存入图片。代码如下:
# --* coding=utf-8 *-- from cStringIO import StringIO from pymongo import MongoClient import gridfs import os import matplotlib.pyplot as plt import matplotlib.image as iming import bson.binary import numpy as np if name == 'main': connect = MongoClient('127.0.0.1', 27017) # 创建连接点 db = connect.mydb print db.collection_names() imgput = gridfs.GridFS(db) dirs = 'G:\image' files = os.listdir(dirs) for file in files: filesname = dirs + '\\' + file print filesname imgfile=iming.imread(filesname) # iming.imsave('s.jpg',imgfile) # print type(imgfile),imgfile # imgfile.shape() plt.imshow(imgfile) plt.axis('off') plt.show() f=file.split('.') print f datatmp=open(filesname,'rb') data=StringIO(datatmp.read()) content=bson.binary.Binary(data.getvalue()) # print content insertimg=imgput.put(data,content_type=f[1],filename=f[0]) datatmp.close()

There are many methods to connect two lists in Python: 1. Use operators, which are simple but inefficient in large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use the = operator, which is both efficient and readable; 4. Use itertools.chain function, which is memory efficient but requires additional import; 5. Use list parsing, which is elegant but may be too complex. The selection method should be based on the code context and requirements.

There are many ways to merge Python lists: 1. Use operators, which are simple but not memory efficient for large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use itertools.chain, which is suitable for large data sets; 4. Use * operator, merge small to medium-sized lists in one line of code; 5. Use numpy.concatenate, which is suitable for large data sets and scenarios with high performance requirements; 6. Use append method, which is suitable for small lists but is inefficient. When selecting a method, you need to consider the list size and application scenarios.

In Python, a for loop is used to traverse iterable objects, and a while loop is used to perform operations repeatedly when the condition is satisfied. 1) For loop example: traverse the list and print the elements. 2) While loop example: guess the number game until you guess it right. Mastering cycle principles and optimization techniques can improve code efficiency and reliability.

To concatenate a list into a string, using the join() method in Python is the best choice. 1) Use the join() method to concatenate the list elements into a string, such as ''.join(my_list). 2) For a list containing numbers, convert map(str, numbers) into a string before concatenating. 3) You can use generator expressions for complex formatting, such as ','.join(f'({fruit})'forfruitinfruits). 4) When processing mixed data types, use map(str, mixed_list) to ensure that all elements can be converted into strings. 5) For large lists, use ''.join(large_li

In Python, you can connect lists and manage duplicate elements through a variety of methods: 1) Use operators or extend() to retain all duplicate elements; 2) Convert to sets and then return to lists to remove all duplicate elements, but the original order will be lost; 3) Use loops or list comprehensions to combine sets to remove duplicate elements and maintain the original order.
