macOS Python newbie help (please read)

[Dmac77]

Hi all,

In the book I'm currently using, I'm working on Module imports. I'm trying to import a module but I'm stuck. The book (Learning Python) has its code written for a DOS window, instead of the terminal, so please forgive me for quoting the DOS commands out of the book, instead of UNIX commands.

So I'm trying to import a script that i wrote earlier that's called "script4". The book says to do the following:

D:\LP3E\Examples> c:\python25\python
>>> import script4
win32
[I]A long string of numbers shows up here[/I]

So I went and started up python in the terminal, and told it to import script4:

Last login: Thu Jan 29 02:27:07 on ttys000
name of computer:~ homefolder$ python
Python 2.5.1 (r251:54863, Nov 11 2008, 17:46:48) 
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import script4
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named script4
>>>

And that is what I get.

I'm totally lost here. If it matters, the script is located at:

~/Developer/script4.py

Thanks!

Try doing cd Developer first so you're in the same directory as the file you're importing.

So when you import a module, the python interpreter will look for that code in a particular set of directories.

If you want to know where it will look just enter:

> import sys
> sys.path

This will show you all the directories where the interpreter will search for your module.

By default, this search path will include your current directory.

So as Catfish_Man said, the easiest way is to be in the directory when you start the interpreter.

Hope that helps.

Sorry that I haven't posted until now. But I was out all day. I followed your guys' advise, and it worked😀 Thanks! I was getting really frustrated last night.
