how to give your data column names based on char position

[whyme]

Hi All

I am very new to python .

I am working with a file with no column header. But the task is to give the file column names based on char positions/substring of data.i have gotten so far to get the first column as below . But i do not know how to actually process the file so it will have column names by the end of it. Please help. Thank you!
