若格式为txt，则先转为Csv格式：

# Author Qian Chenglong
# coding=utf-8
import csv
#要保存后csv格式的文件名
file_name_string="input20181209.csv"
with open(file_name_string, 'w') as csvfile:
    #编码风格，默认为excel方式，也就是逗号(,)分隔
    spamwriter = csv.writer(csvfile, dialect='excel')
    # 读取txt文件，每行按制表符分割提取数据
    with open('input20181209.txt', 'r') as file_txt:
        for line in file_txt:
            line_datas= line.strip('
').split('	')
            spamwriter.writerow(line_datas)
            print(line)
