通过使用其名称（字符串）调用模块的功能 10个答案

我定义了以下字符串，它们指定了python模块名称，python类名称和静态方法名称。

module_name = "com.processors" class_name = "FileProcessor" method_name = "process"

我想调用method_name变量指定的静态方法。

我如何在python 2.7+中实现这一点

Calling a function of a module by using its name (a string) 11 answers

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+

最满意答案

使用__import__函数通过给出模块名称作为字符串来导入模块。

使用getattr(object, name)来访问对象（模块/类或其他 ）的名称

在这里你可以做

module = __import__(module_name) cls = getattr(module, claas_name) method = getattr(cls, method_name) output = method()

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()
