In [3]:
import biogeme.filenames as fl


The role of this function is to obtain the name of a file that does not exist.

In [4]:
theName = fl.getNewFileName('test', 'dat')
theName

Out[4]:
'test~07.dat'

Now, let's create that file, and call the function again. A suffix with a number is appended to the name of the file, before its extension.

In [5]:
open(theName, 'a').close()

In [6]:
theName = fl.getNewFileName('test', 'dat')
theName

Out[6]:
'test~08.dat'

If we do it again, the number is incremented.

In [7]:
open(theName, 'a').close()

In [8]:
theName = fl.getNewFileName('test', 'dat')
theName

Out[8]:
'test~09.dat'
