If you do not want this (new) behavior, you can override it in PYTHONSTARTUP, sitecustomize, or usercustomize by deleting this attribute from sys (or setting it to some other callable). (Contributed by Éric Araujo and Antoine Pitrou in bpo-5845.) tarfile The tarfile module now supports...
This class is the reference implementation of the Element interface. An element's length is its number of subelements. That means if you want to check if an element is truly empty, you should check BOTH its length AND its text attribute. The element tag, attribute names, and attribute valu...

File "<stdin>", line 1, in <module> StopIteration 当在循环中使用时,StopIteration被接受并停止循环。但通过显式引发(invocation),我们看到一旦迭代器元素被耗尽,存取它将引发异常。 使用for...in循环也使用__iter__方法。这允许我们透明地开始对一个序列迭代。但是如果我们已经有一个迭代器,我们想在for循环中...
让用户提交Python代码并在服务器上执行,是一些 OJ、量化网站重要的服务,很多 CTF 也有类似的题。为了不让恶意用户执行任意的 Python 代码,就需要确保 Python 运行在沙箱中。沙箱经常会禁用一些敏感的函数,例如 os,研究怎么逃逸、防护这类沙箱还是蛮有意思的。
TarFile 源码 6、json 和 pickle模块 文件只能存二进制或字符串,不能存其他类型,所以用到了用于序列化的两个模块: json,用于字符串和python数据类型间进行转换,将数据通过特殊的形式转换为所有语言都认识的字符串(字典,变量,列表)。 pickle,用于python特有的类型和python的数据类型间进行转换,将数据通过特殊的形式转...
Do not use this class directly: use tarfile.open() instead. See TarFile Objects.tarfile.is_tarfile(name) Return True if name is a tar archive file, that the tarfile module can read.The tarfile module defines the following exceptions:
The Python Standard Library also supports creating TAR and ZIP archives using the high-level methods in the shutil module. The archiving utilities in shutil allow you to create, read, and extract ZIP and TAR archives. These utilities rely on the lower level tarfile and zipfile modules. Working...
