数据CSV仪表板python

Question

With help from this foro I can create my Optimizator dashboard. Now, I need to make some changes. This is the code:

import csv
import datetime

with open("prueba.csv", 'rb') as f:
    reader = csv.reader(f)
    your_list = list(reader)



mydict = {}
for row in your_list[1:]:
    date = datetime.datetime.strptime(row[0],'%d/%m/%Y')
    name = row[1]
    mydict[(date,name)] = row[2:]


def convert(n):
    n = n.replace(",",".").replace("%","")
    try:
        return float(n)
    except ValueError:
        return 0e0


for (day, name) in mydict:
    previous_day = day - datetime.timedelta(days=1)
    if (previous_day,name) in mydict:
        print name, datetime.datetime.strftime(day,"%d/%m/%Y")
        day2_values = mydict[(day, name)]
        day1_values = mydict[(previous_day, name)]
        comparer = zip(day2_values, day1_values)
        for n,value in enumerate(comparer):
            print "item[%d]:" % (n+2,),
            if convert(value[1]) < convert(value[0]):
                print value[1], "smaller than", value[0], "Incremento"
            else:
                print value[1], "bigger than", value[0], "Descenso"
        print

item[4]: 25.07% bigger than 22.48% Bajada
item[5]: 19.74 bigger than 19.61 Bajada
item[6]: 0.50 smaller than 0.53 Incremento

I need to change the returns items[2],items[3],items[4],items[5] and items[6] for the real names : [['"Fecha"', '"Cliente"', '"Subastas"', '"Impresiones_exchange"', '"Fill_rate"', '"Importe_a_pagar_a_medio"', '"ECPM_medio"']

Also, I need to save the returns in a csv file order by Cliente name. Is it possible??

Answer 1

The real names are in your_list[0] . So change this line

print "item[%d]:" % (n+2,),

to this:

print your_list[0][n+2] + ":",

To save the output as a csv , instead of (or as well as) printing your data out, you need to save it so that you can pass it to csv.writer . Create a list called result , and for every row that you want to see in the output, do

row = [name, datetime.datetime.strftime(day,"%d/%m/%Y"), mylist[0][n+2],value[1], value[0]]
result.append(row)

After you have finished building result , sort it on name:

result.sort()

Use csv.writer() to produce your csv file from this list, one call to the writer object's writerow() method for every row in result .
