Exponential arrival distribution in Python

[Ricky]

Hi all,

I am doing a project on traffic simulation. I want to introduce exponential 
arrival distribution to precede this task. Therefore I want write a code in 
python for exponential arrival distribution. I am very new for programming and 
if anybody can help me on this that would be great.

Cheers,
Ricky

Look at the this line:

if 'one' and 'two' in f:

You're basically saying:

if ('one') and ('two' in f):

which is why you only get elements that contain 'two'.

Try:

def foo(arg={}):
