1.9 使用 pickle 序列化 1.10 CSV 文件的操作 1.11 os 和 os.path 模块 一个完整的程序一般都包括数据的存储和读取;我们在前面写的程序数据都没有进行实际的存储,因此 python 解释器执行完数据就消失了。实际开发中,我们经常需要从外部存储介质(硬盘、光盘、U 盘等)读取数据,或者将程序产生的数据存储到文件中,实...
Using pickle Module If you need to serialize and store Python objects, thepicklemodule is a great choice. This module allows you to serialize and deserialize Python objects, making saving and loading complex data structures easy. import pickle data = { "name": "Dwight Schrute", "age": 40, ...
Python pickle files are the binary files that keep the data and hierarchy of Python objects. They usually have the extension .pickle or .pkl. You can save your DataFrame in a pickle file with .to_pickle(): Python >>> dtypes = {'POP': 'float64', 'AREA': 'float64', 'GDP': '...
pickle.dump(dic,file_object,0) file_object =open('./test.pkl','r') obj = pickle.load(file_object)print(obj) 在python2环境中,可以成功写入文件,并且可以读取文件. 输出 {'key': '111', 'age': 18, 'id': '222', 'value': 333, 'name': 'nihao'} ...
python 打包后 exe 弹出 error no attribute write 在了解相关原理后,下面正式进入打包环节。 本章介绍通过命令行参数进行打包,这种方式比较初级,适用于一般的打包方式。 4.1 基本语法 打包需要通过cmd进行,语法和大多数工具一样。pyinstaller最简单的打包方式是:...
open(file, mode='r', buffering=None, encoding=None, errors=None, newline=None, closefd=True) 打开一个文件,返回一个文件对象(流对象)和文件描述符。打开文件失败,则返回异常 基本使用:创建一个文件test,然后打开它,用完关闭 f =open("test")# file对象 ...

第二个洞是python反序列化:savedata = flask.session.get('savedata', None) data = pickle.loads(base64.b64decode(savedata)) flask用的是客户端session,所以这里pickle.loads()的参数可控。 显然,解题思路是先利用模板注入读到secret_key,再用secret_key伪造session,触发pickle反序列化,导致RCE。先来读secret...
