How to open .z files in downloaded G4Data files and check the cross section data

Hello iquano,

Using the stackexcange post, and adapting the python code posted for uncompression to compression, you can use the following:

import zlib

with open('test', 'rb') as input:
   uncomp=input.read()
   input.close()

z=zlib.compress(uncomp)
   
with open('test.z', 'wb') as f:
   f.write(z)
   f.close()

The input file here is called test, creating the compressed test.z
