背景
我正在构建一个自定义测试运行器,并希望能够根据字符串过滤器选择要运行的模块.有关理想用法,请参阅下面的示例.

module_a.py

def not_mykey_dont_do_this():
    print 'I better not do this'

def mykey_do_something():
    print 'Doing something!'

def mykey_do_somethingelse():
    print 'Doing something else!'

module_b.py

import module_a
list_from_a = dir(module_a) # ['not_mykey_dont_do_this','mykey_do_something','mykey_do_somethingelse']

for mod in list_from_a:
    if(mod.startswith('mykey_'):
        # Run the module
        module_a.mod() # Note that this will *not* work because 'mod' is a string

产量

Doing something!
Doing something else!
