Hi all,
Fairly new Python guy here. I am having a lot of trouble trying to
figure this out. I have some data on some regulations in Excel and I
need to basically add up the total regulations for each country--a
statistical analysis thing that I'll copy to another Excel file.
Writing with pyExcelerator has been easier than reading with xlrd for
me...So that's what I did first, but now I'd like to learn how to
crunch some data.
The input looks like this:
Country Module
Topic # of Docs
Argentina Food and Consumer Products Cosmetics 1
Argentina Food and Consumer Products Cosmetics 8
Argentina Food and Consumer Products Food Additives 1
Argentina Food and Consumer Products Food Additives 1
Australia Food and Consumer Products Drinking Water 7
Australia Food and Consumer Products Food Additives 3
Australia Food and Consumer Products Food Additives 1
etc...
So I need to add up all the docs for Argentina, Australia, etc...and
add up the total amount for each Topic for each country so, Argentina
has 9 Cosmetics laws and 2 Food Additives Laws, etc...
So, here is the reduced code that can't add anything...Any thoughts
would be really helpful.
import xlrd
import pyExcelerator
from pyExcelerator import *
#Open Excel files for reading and writing
path_file = "c:\\1\\data.xls"
book = xlrd.open_workbook(path_file)
Counts = book.sheet_by_index(1)
wb=pyExcelerator.Workbook()
matrix = wb.add_sheet("matrix")
#Get all Excel data
n=1
data = []
while n<Counts.nrows:
data.append(Counts.row_values(n, start_colx=0, end_colx=None))
n=n+1
COUNTRY, MODULE, TOPIC,DOCS = range(4)
COUNTRY_TOT = []
n=0
while n<len(data):
x=n
while data[n][COUNTRY]==data[n+1][COUNTRY]:
n=n+1
print sum(data[x:n][FT_DOCS])
wb.save('c:\\1\\matrix.xls')
