python2.7 rEAD_Csv

import csvwith open('eggs.csv', 'rb') as csvfile: spamreader = csv.reader(csvfile, delimiter=' ', quotechar='|') for row in spamreader: print ', '.join(row)我试了没问题,可能你输入的问题,你拷贝再试试。

具体如下: # _*_ coding:utf-8 _*_ #xiaohei.python.seo.call.me:) #win+python2.7.x import csv csvfile = file('csvtest.csv', 'wb') writer = csv.writer(csvfile) writer.writerow(['id', 'url', 'keywords']) data = [ ('1', 'http://www....

months = months.replace() 好的做法应该是创建一个字典 mDict = {'1':'jan','2':'feb'} months = mDict .get(months, months)

import pandas as pd,numpy as npa = pd.read_csv("aaa.txt")print a.pivot('user_id','brand_id','type')

reader = csv.reader(open('E:/BigData/tianchi_mobile_recommend_train_user.csv','r+')) \t是制表符,直接用/代表\避免 出现 "\t" "\n"这样的转 义符

读取,解析。最后int(str) 如果你的str售有非数字字符,则要先去除掉。 还是不明白?请贴上你的CSV文件相关内容及代码。

File "/usr/lib/python2.7/shutil.py", line 83, in copyfile with open(dst, 'wb') as fdst:IOError: [Errno 13] Permission denied: '/usr/local/...

用chardet查下编码 然后解码 用‘utf-8’编码

拼写错误吧,第三行 fobj 换成 f 试试

具体如下: # _*_ coding:utf-8 _*_ #xiaohei.python.seo.call.me:) #win+python2.7.x import csv csvfile = file('csvtest.csv', 'wb') writer = csv.writer(csvfile) writer.writerow(['id', 'url', 'keywords']) data = [
