Thank you for your attention first.I have a file,there are some columns in the file.I need to be calculated in accordance with column.There is an example:

motif    WSB-1    WSB-2    SM-1    SM-2    PH-1    PH-2    MY-1    MY-2    total 
ATCGAGACTGGGATTTGTCACTCC    62    98    76    64    141    286    124    169    1020
GAACCGGGACTAATGGGCTGACCC    12    26    6    7    36    107    42    32    268
TATTAGTTTACAGAGGGAGTA    10    26    13    10    49    39    46    26    219
ATAGCCACCCAGTTACGTTGTGAC    8    24    8    5    26    71    33    31    206

I need the column of WSB-1 Divided by(/)100,WSB-2/200,SM-1/300,SM-2/400,PH-1/500,PH-2/600,MY-1/700,MY-2/800.

The result should be this

motif    WSB-1    WSB-2    SM-1    SM-2    PH-1    PH-2    MY-1    MY-2    total

If you want to keep the header

awk '{OFS="\t"; if (NR==1) print $0; else print $1,$2/100,$3/200,$4/300,$5/400,$6/500,$7/600,$8/700,$9/800,$10};' input.txt

In python:

from toolshed import reader

for i, d in enumerate(reader("-", header="ordered")):
    if i == 0: print "\t".join(d.keys())
    vals = d.values()
    vals[2:-1] = ["%.3f" % (j * v / 100.) for j, v \
                    in enumerate(map(float, vals[2:-1]), 1)]
    print "\t".join(vals)

reads from stdin and writes to stdout. awk is better until you want to do something slightly different or add/remove columns.
