question about endswith()

[Rafael Durán Castañeda]

I think you want do this:

>>> files = ['file1.hdf', 'file2.hdf', 'file3.hdf5','file4.hdf']
>>> print(''.join(x for x in files if x.endswith('5')))
file3.hdf5
>>>

But if you need to use it later:

>>> file_hdf5 = [x for x in files if x.endswith('5')]
>>> file_hdf5
['file3.hdf5']
>>>
