tempfile: Generate temporary files and directories glob: Unix style pathname pattern expansion Date and time management Date and time management modules provide tools for working with temporal data, timestamps, and calendars in Python applications. These modules offer precise control over time related ...
Or: Put mod.py in one of the directories already contained in the PYTHONPATH variable Put mod.py in one of the installation-dependent directories, which you may or may not have write-access to, depending on the OSThere is actually one additional option: you can put the module file in an...

The PYTHONPATH is an environment variable, consisting of a list of directories. The syntax of PYTHONPATH is the same as that of the shell variable PATH. Here is a typical PYTHONPATH from a Windows system − set PYTHONPATH = c:\python34\lib; And here is a typical PYTHONPATH from a U...

The __init__.py files are required to make Python treat directories containing the file as packages. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later. 2.1导入包中的模...
When you (try to) import a module, the interpreter goes through a process to look for it. The interpreter first searches for a built-in module of that name. If not found, it then searches for a file of that name in a list of directories given by thesys.pathvariable. Thesys.pathvariab...
Each missing directory is associated with an imp.NullImporter instance, since modules cannot be imported from directories that do not exist. In the example output below, several zipimport.zipimporter instances are used to manage EGG files found on the path. $ python sys_path_importer_cache.py ...
variablesys.path. Thesys.pathis a list of strings that specifies the search path for modules. It consists of the current working directory, directory names specified in thePYTHONPATHenvironment variable, and some additional installation dependent directories. If the module is not found, anImportError...
First, the Python interpreter tries to locate the module in the current working directory. If not found, directories in the PYTHONPATH environment variable are searched. If still not found, it searches the installation default directory. As the Python interpreter starts, it put all the above loca...
