python 操作表格

1.常見表格的讀操作
#coding=utf-8
import xlrd
import os
import re
import sys
import time
import datetime
import requests
import chardet
import traceback
import csv
import warnings
warnings.filterwarnings("ignore")


reload(sys)
sys.setdefaultencoding('utf-8')

def print_xls(path):
    data=xlrd.open_workbook(path)   #打開excel
    table=data.sheets()[0] #打開excel的第幾個sheet
    nrows=table.nrows   #捕獲到有效數據的行數
    print nrows
    books=[]
    for i in range(nrows):
        ss=table.row_values(i)   #獲取一行的所有值，每一列的值以列表項存在
        url = ss[0]
        # for i in range(len(ss)):
        #     print ss[i]            #輸出一行中各個列的值
        #     print '+++++++++++++++++++'
        print url
        pass

def read_csv(path):
    file = open(path)
    reader = csv.reader(file)
    for line in reader:
        site = ''
        for row in line[0:1]:
            site = site + row.decode('utf-8')
            pass
        for row in line[3:]:
            site = site + row.decode('utf-8')
            pass
        print site    
    pass

if __name__ == '__main__':
    db_client = MongoClient('192.168.86.136',27017)
    read_csv(u'黃山市學校數據.csv')
    print_xls(u'黃山市學校數據.xls')

db_client.close()
