modulefinder
— 查找用于脚本的模块
¶
源代码： Lib/modulefinder.py
This module provides a
ModuleFinder
class that can be used to determine the set of modules imported by a script.
modulefinder.py
can also be run as a script, giving the filename of a Python script as its argument, after which a report of the imported modules will be printed.
modulefinder.
AddPackagePath
(
pkg_name
,
path
)
¶
Record that the package named pkg_name can be found in the specified path .
modulefinder.
ReplacePackage
(
oldname
,
newname
)
¶
Allows specifying that the module named oldname is in fact the package named newname .
modulefinder.
ModuleFinder
(
path=None
,
debug=0
,
excludes=[]
,
replace_paths=[]
)
¶
This class provides
run_script()
and
report()
methods to determine the set of modules imported by a script.
path
can be a list of directories to search for modules; if not specified,
sys.path
被使用。
debug
sets the debugging level; higher values make the class print debugging messages about what it’s doing.
excludes
is a list of module names to exclude from the analysis.
replace_paths
是列表化的
(oldpath, newpath)
tuples that will be replaced in module paths.
report
(
)
¶
Print a report to standard output that lists the modules imported by the script and their paths, as well as modules that are missing or seem to be missing.
run_script
(
pathname
)
¶
Analyze the contents of the pathname file, which must contain Python code.
modules
¶
A dictionary mapping module names to modules. See Example usage of ModuleFinder .

The script that is going to get analyzed later on (bacon.py):
import re, itertools try: import baconhameggs except ImportError: pass try: import guido.python.ham except ImportError: pass
The script that will output the report of bacon.py:
from modulefinder import ModuleFinder finder = ModuleFinder() finder.run_script('bacon.py') print('Loaded modules:') for name, mod in finder.modules.items(): print('%s: ' % name, end='') print(','.join(list(mod.globalnames.keys())[:3])) print('-'*50) print('Modules not imported:') print('\n'.join(finder.badmodules.keys()))
Sample output (may vary depending on the architecture):
Loaded modules: _types: copyreg: _inverted_registry,_slotnames,__all__ sre_compile: isstring,_sre,_optimize_unicode _sre: sre_constants: REPEAT_ONE,makedict,AT_END_LINE sys: re: __module__,finditer,_expand itertools: __main__: re,itertools,baconhameggs sre_parse: _PATTERNENDERS,SRE_FLAG_UNICODE array: types: __module__,IntType,TypeType --------------------------------------------------- Modules not imported: guido.python.ham baconhameggs
