In normal Python yes, you can simply pass the file name as an
argument to the program or you can use input redirection to
read the data from the file as if it were input by a user.

Unfortunately neither of these options is likely to work in
a web environment - one of the disadvantages of using such
a tool. The issue is not a Python one but one with your
tutorial. I suggest you contact the authors directly to
ask if they can suggest a solution (or incorporate
such a feature).

In real-world python you could just use input redirection:

########## data.txt ##########
Alan
##############################

########## myscript.py #######
name = raw_input("What's your name? ")
print "Hello ", name
##############################

Executed with:

$ python myscript.py < data.txt
