question about endswith()

[Matt Funk]

Hi,

thanks guys. This is it. The following code will match both hdf and hdf5
for reasons explained in the email from Ethan.

extensions = 'hdf5' #doesn't work
files =
('MOD03.A2010002.1810.005.2010258062733.hdf','MOD03.A2010002.1950.005.2010258063105.hdf','MOD03.A2010002.1950.005.2010258063105.hdf5')
for filename in files:
    if (any(filename.endswith(x) for x in extensions)):
        print filename

The following code will work:
extensions = ['hdf5'] #works
files =
('MOD03.A2010002.1810.005.2010258062733.hdf','MOD03.A2010002.1950.005.2010258063105.hdf','MOD03.A2010002.1950.005.2010258063105.hdf5')
for filename in files:
    if (any(filename.endswith(x) for x in extensions)):
        print filename


thanks for the help
matt
