I have a the following strings defined which are specifying a python module name, a python class name and a static method name.
module_name = "com.processors"
class_name = "FileProcessor"
method_name = "process"
I would like to invoke the static method specified by method_name variable.
How do i achieve this in python 2.7+
Use __import__ function to import module by giving module name as string.
Use getattr(object, name) to access names from an object (module/class or anything)
Here u can do
module = __import__(module_name)
cls = getattr(module, claas_name)
method = getattr(cls, method_name)
output = method()
You can use importlib for this.
Try importlib.import(module +"." + class +"."+ method)
Note that this concatenated string should look exactly like if you would import it via import module.class.method
Try this:
# you get the module and you import
module = __import__(module_name)
# you get the class and you can use it to call methods you know for sure
# example class_obj.get_something()
class_obj = getattr(module, class_name)
# you get the method/filed of the class
# and you can invoke it with method()
method = getattr(class_obj, method_name)
