How to dynamically load a class in different location and get the method names in the class in python

Question

I have wriiten the Simple class .py file which has the class class Employee:

empCount = 0

def __init__(self, name, salary):
    self.name = name
    self.salary = salary
    Employee.empCount += 1

def displayCount(self,salary):
    print "Total Employee %d" % Employee.empCount

def displayEmployee(self):
    print "Name : ", self.name,  ", Salary: ", self.salary

and now i have written the another script to import the file and get the methods in the class but i am not able to fetch the methods

import inspect
import sys
pat="E://pythonscripts"
sys.path.append(pat)

#pat="E:/pythonscripts/Simpleclass"
__import__('Simpleclass', globals={})

for name, method in inspect.getmembers('Simpleclass', inspect.ismethod):
    print name
    (args, varargs, varkw, defaults) = inspect.getargspec(method)
    for arg in args:
        print arg

when running the inspect script i am getting the following error

Traceback (most recent call last):
  File "C:/Python27/stack.py", line 9, in <module>
    for name, method in inspect.getmembers(Employee, inspect.ismethod):
NameError: name 'Employee' is not defined

Answer 1

Add path of the employee.py module in sys.path

import sys
sys.path.append(<directory of employee.py module>)

For import dynamic module use __import__

__import__('employee', globals={})

OR

importlib

You can use inspect for introspecting python class

import inspect

for name, method in inspect.getmembers(<your class>, inspect.ismethod):
    print name
    (args, varargs, varkw, defaults) = inspect.getargspec(method)
    for arg in args:
        print arg
