pip install unicodecsv==0.14.1 要了解更多关于unicodecsv库的信息,请访问github.com/jdunck/python-unicodecsv。 除此之外,我们将继续使用从第八章开发的pytskutil模块,与取证证据容器配方一起工作,以允许与取证获取进行交互。这个模块在很大程度上类似于我们之前编写的内容,只是对一些细微的更改以更好地适应我们的...
AssertionError Raised when the assert statement fails. AttributeError Raised on the attribute assignment or reference fails. EOFError Raised when the input() function hits the end-of-file condition. FloatingPointError Raised when a floating point operation fails. GeneratorExit Raised when a generator'...
handle = CreateFile(dest_file, GENERIC_WRITE, FILE_SHARE_WRITE,None, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,None) SetFileTime(handle, created, accessed, modified) CloseHandle(handle) 一旦我们有了一个打开的文件句柄,我们可以调用SetFileTime()函数按顺序更新文件的创建、访问和修改时间戳。设置了目标文件的时...
import fooclassBar(object): ...def__del__(self): foo.cleanup(self.myhandle) And you then tried to do this fromanother_mod.py: importmodmybar =mod.Bar() You’d get an uglyAttributeErrorexception. Why? Because, as reportedhere, when the interpreter shuts down, the module’s global va...
The Pythonic solution for attribute privacy is to use properties. There are two ways to do this. The first way is to add name = property(get_name, set_name) as the final line of our previous Duck class definition: >>> class Duck(): >>> def __init__(self, input_name): >>> se...
2、使用按属性选择图层工具(Select Layer by Attribute)选择要素和行 按属性选择工具利用要素图层或表视图以及查询条件和选择类型来选择记录。默认情况下,选择类型设置为创建一个新选择内容。其他的选择类型包括”添加到当前选择内容“,”从当前选择内容中移除“,”从当前选择内容中选择“,”切换选择内容“以及”清除选择...
在之前的学习中,我们多次提到使用函数,比如print(), len()等。对函数的解释在第五期中也有详细讲到,读者们可以前往查看。 本期,我们将学会如何定义属于自己的函数,我们将学会把自己所希望的动作包装在一个函数中,并在需要的时候随时将这一系列动作调出来使用,它的样子将会和我们之前见到的其他函数类似: ...
attrs.filters.exclude() and attrs.filters.include() now support the passing of attribute names as strings. #1068 attrs.has() and attrs.fields() now handle generic classes correctly. #1079 Fix frozen exception classes when raised within e.g. contextlib.contextmanager, which mutates their __tr...
