Using print in a python script gives the following result:

10.25, 9.23, 8.97, 8.71, 8.40, 8.36, 8.30, 8.21
10.25, 9.23, 8.97, 8.71, 8.40, 8.36, 8.30, 8.61
0.15, 0.15, 0.15, 0.15, 0.15, 0.15, 0.15, 0.15
0.60, 0.60, 0.60, 0.60, 0.50, 0.50, 0.50, 0.15
4.85, 2.85, 1.85, 1.25, 0.95, 0.85, 0.80, 0.45
1.35, 1.35, 1.35, 1.35, 1.10, 1.10, 1.10, 0.15
0.60, 0.60, 0.60, 0.60, 0.50, 0.50, 0.50, 0.15
0.40, 0.40, 0.40, 0.40, 0.40, 0.40, 0.40, 0.15
2.84, 1.84, 1.08, 0.58, 0.50, 0.25, 0.18, 0.15
26.85, 23.83, 21.57, 20.71, 19.85, 18.71, 17.60, 13.96

What is the easiest way to write/print this to a (csv) file ?

You could use something like this ...

raw_data = '''\
10.25, 9.23, 8.97, 8.71, 8.40, 8.36, 8.30, 8.21
10.25, 9.23, 8.97, 8.71, 8.40, 8.36, 8.30, 8.61
0.15, 0.15, 0.15, 0.15, 0.15, 0.15, 0.15, 0.15
0.60, 0.60, 0.60, 0.60, 0.50, 0.50, 0.50, 0.15
4.85, 2.85, 1.85, 1.25, 0.95, 0.85, 0.80, 0.45
1.35, 1.35, 1.35, 1.35, 1.10, 1.10, 1.10, 0.15
0.60, 0.60, 0.60, 0.60, 0.50, 0.50, 0.50, 0.15
0.40, 0.40, 0.40, 0.40, 0.40, 0.40, 0.40, 0.15
2.84, 1.84, 1.08, 0.58, 0.50, 0.25, 0.18, 0.15
26.85, 23.83, 21.57, 20.71, 19.85, 18.71, 17.60, 13.96
'''

space = ' '
csv_data = ""
for c in raw_data:
     if c != space:
         csv_data += c

print(csv_data)

'''result ...

'''

This is how I solved it, maybe not the most elegant way but it works:

    for line in cline:
        outFile.write(line)
    outFile.write('\n')
    outFile.close
