Python didn't make that assumption, the author of the script did.  By 
using a relative name like train.csv, he is implicitly forcing Python to 
use the current working directory.

If he had wanted the file to be found in the same directory as one of 
the source files, he could have built an absolute path by using the 
__file__ attribute of the module.

However, for non-const files, the source directory is generally a bad 
place to put them.

Confounding things is the strange habit that Windows has of deciding 
that the script location *should* be your current directory.  I believe 
Explorer does that if you right-click select a script.
