我有一个UTF-16 CSV文件,我必须阅读.Python csv模块似乎不支持UTF-16.
我使用的是python 2.7.2.我需要解析的CSV文件是大量运行到几GB的数据.
John Machin的答案问题如下
print repr(open('test.csv', 'rb').read(100))
输出test.csv只有abc作为内容
'\xff\xfea\x00b\x00c\x00'
我认为csv文件是在美国的Windows机器上创建的.我正在使用Mac OSX Lion.
如果我使用phihag提供的代码和包含一条记录的test.csv.
示例test.csv使用的内容.下面是print repr(open('test.csv','rb').read(1000))输出
'\xff\xfe1\x00,\x002\x00,\x00G\x00,\x00S\x00,\x00H\x00 \x00f\x00\xfc\x00r\x00 \x00e\x00 \x00\x96\x00 \x00m\x00 \x00\x85\x00,\x00,\x00I\x00\r\x00\n\x00'
代码由phihag
import codecs
import csv
with open('test.csv','rb') as f:
sr = codecs.StreamRecoder(f,codecs.getencoder('utf-8'),codecs.getdecoder('utf-8'),codecs.getreader('utf-16'),codecs.getwriter('utf-16'))
for row in csv.reader(sr):
print row
输出上面的代码
['1', '2', 'G', 'S', 'H f\xc3\xbcr e \xc2\x96 m \xc2\x85']
['', '', 'I']
预期产量是
['1', '2', 'G', 'S', 'H f\xc3\xbcr e \xc2\x96 m \xc2\x85','','I']
我正在尝试使用Python Pandas导入CSV文件.此文件中的示例数据如下所示,其中第一行是以逗号分隔的列名.
End Customer Organization ID,End Customer Organization Name,End Customer Top Parent Organization ID,End Customer Top Parent Organization Name,Reseller Top Parent ID,Reseller Top Parent Name,Business,Rev Sum Division,Rev Sum Category,Product Family,Version,Pricing Level,Summary Pricing Level,Detail Pricing Level,MS Sales Amount,MS Sales Licenses,Fiscal Year,Sales Date
