[Python知识库]python获取照片EXIF信息

一、前言

目前好多照片都已经抹掉了设备信息、拍摄时间和GPS信息这种比较隐私的信息，除去这这种信息，其他的信息一般照片都能拿到。文末会给出可以查到完整信息的图片做参考。

二、准备

主要是用python的ExifRead库获取照片信息

三、代码实现

1 安装依赖包

pip install exifread

2 具体代码

# -*- coding: utf-8 -*-
import exifread

def read():
	with open("001.jpg", 'rb') as f:
		tags = exifread.process_file(f)
		for tag in tags.keys():
			if tag not in ('JPEGThumbnail', 'TIFFThumbnail', 'Filename', 'EXIF MakerNote'):
				print("%s:, %s" % (tag, tags[tag]))

if __name__ == '__main__':
	read()
