我想在python中排序csv文件。在python中沒有發生csv排序
這裏是我的CSV文件
貓SampleData.csv
OrderDate,Region,Rep,Item,Units,Unit Cost,Total
1/6/14,East,Jones,Pencil,95, 1.99 , 189.05
1/23/14,Central,Kivell,Binder,50, 19.99 , 999.50
2/9/14,"Central","Jardine","Pencil",36, 4.99 , 179.64
2/26/14,Central,Gill,Pen,27, 19.99 , 539.73
3/15/14,West,Sorvino,Pencil,56, 2.99 , 167.44
4/1/14,East,Jones,Binder,60, 4.99 , 299.40
4/18/14,Central,Andrews,Pencil,75, 1.99 , 149.25
5/5/14,Central,Jardine,Pencil,90, 4.99 , 449.10
5/22/14,West,Thompson,Pencil,32, 1.99 , 63.68
6/8/14,East,Jones,Binder,60, 8.99 , 539.40
12/4/15,Central,Jardine,Binder,94, 19.99 ," 1,879.06 "
12/21/15,Central,Andrews,Binder,28, 4.99 , 139.72
這裏是我的代碼
import csv
import operator
f = open('SampleData.csv')
csv1 = csv.reader(f, delimiter=',')
sort = sorted(csv1, key=operator.itemgetter(6))
for eachline2 in sort:
print eachline2
f.close()
這裏是我的結果:
['12/4/15', 'Central', 'Jardine', 'Binder', '94', ' 19.99 ', ' 1,879.06 ']
['12/21/15', 'Central', 'Andrews', 'Binder', '28', ' 4.99 ', ' 139.72 ']
['4/18/14', 'Central', 'Andrews', 'Pencil', '75', ' 1.99 ', ' 149.25 ']
['3/15/14', 'West', 'Sorvino', 'Pencil', '56', ' 2.99 ', ' 167.44 ']
['2/9/14', 'Central', 'Jardine', 'Pencil', '36', ' 4.99 ', ' 179.64 ']
['1/6/14', 'East', 'Jones', 'Pencil', '95', ' 1.99 ', ' 189.05 ']
['4/1/14', 'East', 'Jones', 'Binder', '60', ' 4.99 ', ' 299.40 ']
['5/5/14', 'Central', 'Jardine', 'Pencil', '90', ' 4.99 ', ' 449.10 ']
['6/8/14', 'East', 'Jones', 'Binder', '60', ' 8.99 ', ' 539.40 ']
['2/26/14', 'Central', 'Gill', 'Pen', '27', ' 19.99 ', ' 539.73 ']
['5/22/14', 'West', 'Thompson', 'Pencil', '32', ' 1.99 ', ' 63.68 ']
['1/23/14', 'Central', 'Kivell', 'Binder', '50', ' 19.99 ', ' 999.50 ']
['OrderDate', 'Region', 'Rep', 'Item', 'Units', 'Unit Cost', 'Total']
我不是肯定我做什麼錯了在這裏。
我這裏有兩個問題,你看
- 排序沒有發生。
- 我在最後一行得到標題。我想在第一行。
任何幫助極大的讚賞。
數據排序非常好。看看'sorted(['Total','1,879.06','999.50'])''的輸出。如果你打算用csv文件做很多工作,你可以查看http://pandas.pydata.org/ – YXD
