Looping a script on 700+ files?

AT510_67__30_4_16__4_58_12.csv AT510_67__9_5_16__17_20_55.csv
AT510_67__13_5_16__18_52_52.csv AT510_67__16_5_16__12_22_6.csv AT510_67__2_5_16__12_12_39.csv AT510_67__30_4_16__5_58_12.csv AT510_67__9_5_16__18_20_55.csv
AT510_67__13_5_16__19_52_52.csv AT510_67__16_5_16__1_22_6.csv AT510_67__2_5_16__13_12_39.csv AT510_67__30_4_16__6_58_12.csv

Here's a bunch of files I am converting to hdf5s using a python script, running from the command line.
How would I loop this command?
python AT510_67__2_5_16__13_12_39.csv 2/5/16/13/12/39.h5
The AT510 is common to all files. I'd really like it if there was a way to name the new files with the date and time.

The format is

python csvinputfile h5output file

The date program can provide formatted output. If you wrap that in a command substition you can get a name that includes the date and time.

python $cvsinputfile $(date +'%F-%H-%M-%S.h5')

As suggested, a for loop should be the ticket. A few observations:

1. If running on multiple machines, the call to python may come unstuck if it should point to 3.X or 2.X and will throw errors if the wrong one is used. If you place the interpreter at the head of the file
and make the file executable, you can simply run the script without issue

2. Assuming the path to 'h5' file may need to be created from the file name, you could also do this in the loop
