python Csv.rEADEr

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

import csvwith open('eggs.csv', newline='') as csvfile: spamreader = csv.reader(csvfile, delimiter=',', quotechar=',') for row in spamreader: print(', '.join(row))

用csv模块 import csvcsvfile = file('test.csv', 'rb')reader = csv.reader(csvfile)for line in reader: print linecsvfile.close()

import csvfor row in csv.reader(open('sales.csv','rb')): for col in row: print col

a_list, c_list = [], [] reader = csv.DictReader(file('1.csv', 'rb')) for i in reader: a_list.append(i.get('a')) c_list.append(i.get('c')) print a_list print c_list print zip(a_list, c_list)

参考方法如下: 逐行处理: for line in open("samples/sample.csv"): title, year, director = line.split(",") //以“,”号为分割,按逗号将数据分成三部分; print year, title 使用csv模块处理: import csv reader = csv.reader(open("sample...

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。

用chardet查下编码 然后解码 用‘utf-8’编码

class DBI(object): """database interface""" def __init__(self, conn): """keep connection""" self._conn = conn def store(self, sql, data): """store data into database with given sql""" curr = self._conn.cursor() curr.executemany...

csv文件内每一行即一行数据,每一个逗号为一列数据。因此,先按行读取一行,再按逗号分割即可。 csvfile = open('your_csv_file.csv', 'r')data = []for line in csvfile: data.append(list(line.strip().split(','))) 此外,numpy.loadtxt也提...
