      Thanks BV. Could you please show me detailed explanation about the consistency?
      I've read the description about imports in PEP08, but I think I am still puzzled about that....

        in Python
        Hi,

        I think wxPython can help you to develop GUI function, including the input/output.

        You can use wx.TextCtrl to get the input from the user, and then use os.listdir('PAT H') to enumerate the files.
        Note: PATH is the input got from user.

        I can give you a sample to use wxPython
        wxpython TextCtrl Basic Formatting - Python

        and the help for TextCtrl
        wx.TextCtrl

          Questions about the import ordering

          Dear all,

          I am reading the book "Core Python Programming". In the chapter talking about modules, it says the modules should follow this ordering:

          Code:
          import Python Standard Library modules

import Python third party modules

import Application-specific modules
          I am not sure whether the ordering will impact the module's loading or search efficiency. For example, a common...

            replied to A question about "Intra-package References"
            in Python
            Thank you. I've got the answer why the error happened.

            "Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application should always use absolute imports."

            So I made another main module with absolute imports, and also imports this test module. Everything is fine.

            Thanks again for your help:)
            Have a nice day!

              A question about "Intra-package References"

              Hi all,

              I have a simple question about "Intra-package References"
              There are two source files and __init__.py in package MyPkg shown below:

              |-MyPkg
              -__init__.py
              -example.py
              -test.py

              example.py is like this:
              Code:
              a = 5
              and test.py is like this:
              Code:
              from . import example

print example.a
              While I executed test.py, python...

                replied to Question about "global" statement
                in Python
                I found another solution to this problem.

                I can use a name space for the scoping.

                __main__.a will be referenced to a global variable.

                Anyway, I think container is better.

                    Question about "global" statement

                    Hi,

                    I am having trouble understanding the use of 'global' variables I want to use a global variable with the same name as a parameter of a function. But I don't know how to use them at the same time. Here is a snippet of example code:

                    Code:
                    def foo (a):
    global p
    global a
    p = a + 3  #here "a" will be reference to the global one
    
a = 1
p = 0
foo (a)
                    ...
