正常的csv文件讀取如下：

#coding:utf-8
import csv
csvfilename = ‘demo.csv‘


print u‘################獲取某一行‘
with open(csvfilename, ‘rb‘) as csvfile:
    reader = csv.reader(csvfile)
    rows = [row for row in reader]
print rows[0], rows[1], rows[2], rows[3]

print u‘################獲取某一列‘
with open(csvfilename,
 
‘rb‘) as csvfile:
    reader = csv.reader(csvfile)
    column0 = [row[0] for row in reader]
with open(csvfilename, ‘rb‘) as csvfile:
    reader = csv.reader(csvfile)
    column1 = [row[2] for row in reader]

print column0, column1
s = [1,2,3]
for i in column0:
    print type(i)
# print u‘sum:‘,sum(column0)
 

new_column0 = column0.pop(0)
print u‘刪除的元素為：‘, new_column0
print u‘刪除後的列表:‘, column0
print type(column0)
for i in column0:
    print type(i)

讀取一個 ucs-2 le 格式（notepa++打開csv）的csv就會報錯： Python CSV error: line contains NULL byte 參考了這個文章裏面的內容

https://stackoverflow.com/questions/4166070/python-csv-error-line-contains-null-byte

代碼如下：

#coding:utf-8
import csv
import codecs

twsfilename = "tws.csv"

#讀取行
print u‘################獲取某一行‘
with codecs.open(twsfilename, ‘rb‘, "utf-16") as csvfile:
    reader = csv.reader(csvfile)
    column1 = [row[0] for row in reader]
    print column1[0]

print u‘################獲取某一列‘
with codecs.open(twsfilename, ‘rb‘, "utf-16") as csvfile:
    reader = csv.reader(csvfile, delimiter=‘\t‘)
    reader.next()#向下跳一行 這行可以註釋掉  主要為了去掉標題行
    column1 = [row[1] for row in reader]
    print column1
    print max(column1)

最後感謝大神 參考了很多都搞不定 什麽.replace(‘\0‘,‘‘)啊 另存啊 都搞不定 給你幾百個這種csv你難道一個個另存啊！
