[BangPypers] Need help for python coding

[Jonathan Toomim]

1. str is the name of a builtin type object. If you create a variable 
with that name, then you will be unable to access that builtin type 
while your variable remained in scope. This would mean that you would be 
unable to call str(42), for example.

2. Perhaps the csv module can be of use to you? 
http://docs.python.org/2/library/csv.html

3. There's an easier way to test if there's a substring present in a string:

for line in f_read:
     if 'VON MISES' in line:
         print m

If you want case insensitivity, just replace line with line.upper().

4. By the way, you could probably also do this in one line from bash 
using grep:

grep "VON MISES" "file name" > "output file"
