excel - Finding all instances where a matchword is used in a csv file using python -


i have csv file has numerous columns

here image of excel file looks http://i.stack.imgur.com/ab6tp.png

i need through thousands of rows, in column labeled hit definition virus name "grapevine" in it. each word name "grapevine", need compile how many times mentioned, range of length (column labeled query length, [2]), , summation of reads(column total reads, [4]).

input: http://i.stack.imgur.com/ab6tp.png

output:

grapevine 1 6 234-234234 45634

grapevine 2 7 123-65432 12341

with open(argv[1], 'r') f:    line in csv.reader(f):                  contig_name = line[0]            contig_length = line[3]            read_count = line[4]            hit_def = line[6]             try:                    pattern = r'.\[(.*?)\].'                    hit_sub = re.search(pattern, hit_def).group(1)                    print hit_sub            except attributeerror:                    hit_sub = hit_def                      target.append([hit_sub])

this have far lost on how filter names

since you're lost on how filter names, try:

re.findall("grapevine",f)
