Simple python-abaqus question

[Cansand]

I am learning Python... while going through a simple example in the Doc
I have copied the statements below into a file called distance.py in my local directory C.
Then (as instructed in the ABAQUS Doc) I typied the following at the system prompt:

abaqus python distance.py 30 40

but the ABAQUS\6.5.1\cae\python.exe: can't open file'distance'

can anybody tell me why. in addition what are '30 40' for in the statement abaqus python distance.py 30 40


import sys, math
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
def distance(x, y):
"""
Prints distance from origin to (x, y).

Takes two command line arguments, x and y.
"""

# Square the arguments and add them.

a = x**2 + y**2

# Return the square root.

return math.sqrt(a)

# Retrieve the command line arguments and
# convert the strings to floating-point numbers.

x = float(sys.argv[1])
y = float(sys.argv[2])

# Call the distance function.

d = distance(x, y)

# Print the result.

print 'Distance to origin = ', d

1. You should run the command in the same directory as you saved the "distance.py" file.

2. If you look at the commands in your script:
x = float(sys.argv[1])
y = float(sys.argv[2])
you'll understand what the "30 40" mean. They are "arguments". Python processes arguments just like other programming languages (C, C++, perl etc etc)

Finally, you should check out a good genreal python programming guide such as Practical Python. You'll get a lot of good background understanding such as this...

It is definitely helpful forum regardless of coming across some curious and arrogant replies sometimes.
