Re: Persistent Error: Python was not found

[Mike Dewhirst]

This is what I would do ...

1.    Download Python from python.org not Microsoft

2.    Install as an expert or custom install to C:\Python310 rather than 
C:\Program files


3.    Ignore this point - I was going to mention VirtualEnv which comes 
later for software development and thereafter you don't need to put 
Python on the Windows path. As I said, ignore this point.


4.    Add C:\Python310\Scripts to the path (system or user)

5.    Add C:\Python310 to the path after C:\Python310\Scripts

6.    Open a cmd prompt and enter python to prove it starts then quit. 
Exit the cmd window


7.    Create a directory in the root of your user profile 
(C:\Users\Jonathan ??) called pythontest


8.    Save 'print("hello world")' in a text file called hello.py in the 
above directory


9.    Open a cmd prompt and type > python 
C:\Users\Jonathan\pythontest\hello.py


Should work.

If you want to execute a python script without first opening a cmd 
prompt, you need a bat file or shortcut which contains the command line 
you want executed. Give that a double-click and it should also work.


If Python is on the path you don't need to specify where it is.

You do need to tell Python what you want it to execute.

It is possible that you can associate .py files with Python but that 
would be a step too far for me.


Good luck

Re: Conecting to MySQL

MySQL can listen on a local unix socket (named pipe in Windows), an
internet TCP/IP port, or both.  If your MySQL is running, it could be
listening on the local socket or named port, which has a different url
than localhost:3306.  MySQL can be configured to also listen on a TCP/IP
port, which is what you code is apparently expecting.

Although the fact that your MySQL Workbench cannot connect either
suggests that MySQL is not running at all.

Configuring MySQL is a bit beyond the scope of this list, although I'm
sure there are people here who know how to do it.  What OS are you using?

RE: [Tutor] (no subject)

[avi.e.gross]

How long?

Not fibbing but infinite is infinite and I simply so not have the time.

This is so such an EASY question that you need to show some work to interest
us.

You can do this in ANY programming language so explain if there is a reason
you ask here or ...

The real question is what you want. Do you want an algorithm, perhaps in a
function, that returns the first N numbers in the sequence, or one that can
start with an alternate sequences than the usual 0/1 or perhaps do you want
a generator that will return one number at a time infinitely, or until the
world ends, or someone pulls a power cord, whichever is sooner?
