[Python] A low-level error/XXX instance have no attribute ' xxx '/' module ' object is not callable

The following two errors occurred while writing the code today:

TypeError: ' Module ' object is not callable

' Xlbook '

On the Internet, found that the first error is because there are two different references in Python, import xxx and from XXX import *, the former in the code to reference the need to add the module name and the specific method or property, the method is as follows:

Import= Catchform.catchform ()

The From XXX Import * can be directly referenced by:

 from Import *= Catchform ()

After solving the first error, and immediately encountered the second error, baffled the solution, my code is as follows:

 class Excelchange: 
     "" a win32com wrapper class that encapsulates all of its methods, 
                          Unified call 
     "" 
     def _init_ (self,filename = None): #传入文件名参数, if any, Do not assign the None to filename, and then create a new 
         Self.xlapp = Dispatch (' Excel.Application ') 
         if filename: 
              self.filename = filename 
              Self.xlbook = self.xlApp.Workbooks.Open (filename) 
          Else: 
             Self.xlbook = SELF.XLAPP.WORKBOOKS.ADD () 
             self.filename = ' 

I see, xlbook this does not have, why error, finally on the internet to find:

My _init_ is wrong, the correct writing should be __init__, there are two underline =. =

囧rz

Summary: The code still has to write very often AH =. = Especially in a company where a leader blindly believes in automation (which thinks that automation is all-rounder), it is over when it is finished.
