I've been working on this cli based python 3.x app for a friends shop.
So far, everything is working well. We are now ready to start
development on a new module of my code.
The shop is a repair shop, and I've already done the code for client
management and employee management and all the framewo

Hi,
Is there any way I can use named tuples in Python 2.5? It's available since 2.6
and I'm not sure if from "__future__" works. I can't try it here.
I cannot simply upgrade Python (alas!)
Maybe this'll help...

OK, Don't use eval or exec they have secuity issues - especially if
reading the
strings from a file!
idea is to read in strings from a file, look one
Here's your hint... to execute a Python function, it must be followed by
parentheses otherwise you are just referring to the function object.

Hi,
If you can get away with not telling me the answer, but pointing me to where to
look for the answer, I'd be grateful.
In my Python learning, I am just now starting to understand how to make classes
and extend them, so I have a very long way to go.
I wrote this code because I wanted to avoid
Instead of nested fors which will grow exponentially in running time, consider
this for removing reversals:
newlist = []
tempdict = {}
for i in oldlist:
try:
tempdict[i]
except:
tempdict[i] = 1
tempdict[i.reverse()] = 1
newlist.append(i)
That's the gneral

This uses repr() to display the result

This uses str() to display the result.
In many cases str() calls repr() but in other cases str() is a more
