Problem Running Module in PyCharm 96.742 Console
I created a new class in Python:
__author__ = 'Michael'
class chapter2(object):
"""Core Python Programming chapter2"""
version = 1.0 # class static attribute
def __init__(self, name='first class'):
"""constructor"""
self.name = name
print 'Create your first Python class'
def show(self):
"""display instance attribute and class name"""
print ' instance ', self.name
print ' class ', self.__class__.__name__
print ' version ', self.version
def exercise1(self):
"""Core Python Programming exercise 2.1"""
s = 'Duffy'
i = 2
x = 3.141592643489759
print 's = ', s
print 'i = ', i
print 'x = ', x
def exercise2(self):
"""Core Python Programming exercise 2.2"""
return 1 + 2 * 4
I can import the class successfully, but when I use "dir()" I don't see function "exercise2", and I can't instantiate an instance. Here's the output I see in the console:
C:\Tools\Python-2.6.1\python.exe -u C:\Program Files\JetBrains\PyCharm 96.742\helpers\pydev\console\pydevconsole.py 2896 2897
import sys; print('Python %s on %s' % (sys.version, sys.platform))
Python 2.6.1 (r261:67517, Dec 4 2008, 16:51:00) [MSC v.1500 32 bit (Intel)] on win32
sys.path.append('C:/Documents and Settings/Michael/My Documents/Projects/Python/learning/core')
>>> import chapter2
>>> dir(chapter2)
['__author__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', 'chapter2']
>>> ch2 = chapter2()
File "<console>", line 1, in <module>
TypeError: 'module' object is not callable
Traceback (most recent call last):
Can anybody tell me what I'm missing? Why can I not instantiate my class? Why don't the methods exercise1() and exercise2() appear? I've attached a screen shot. Thanks.

This error statement TypeError: 'module' object is not callable is raised as you are being confused about the Class name and Module name. The problem is in the import line . You are importing a module, not a class. This happend because the module name and class name have the same name .
If you have a class "MyClass" in a file called "MyClass.py" , then you should import :
from MyClass import MyClass
In Python , a script is a module, whose name is determined by the filename . So when you start out your file MyClass.py with import MyClass you are creating a loop in the module structure.
