So, i have this code in python that i'm running. The input file is named input2.txt and looks like

1.8 4.5 1.1 2.1 9.8 7.6 11.32 3.2 0.5 6.5

The output2.txt is what i'm trying to achieve but when the code runs is comes up blank The output doc is created and the code doesn't error out. it should look like this

Sample Program Output

Any helps would be great.

Thanks
