Python 将CSV从两行转换为带有时间戳的列

我有一个CSV文件，格式为两行，其中包含24小时的数据： （逗号分隔。我在原来的问题中没有指定，对不起！）

我需要把它转换成我可以在另一个过程中使用的格式。它包含完整的时间戳、值和Building ref。我将把它推送到一个MySQL表中

Building,   Kwh,    Timestamp
A,  2,  12/06/15 00:30
A,  3,  12/06/15 01:00
A,  4,  12/06/15 01:30
A,  4,  12/06/15 02:00
A,  2,  12/06/15 02:30
A,  3,  12/06/15 03:00

我已尝试使用此方法来透视数据：

import csv

from itertools import izip
a = izip(*csv.reader(open("Logger.csv", "rb")))
csv.writer(open("Long.csv", "wb")).writerows(a)

但这给了我四行的标题和两行的数据。 只有从今天的Python开始，我才能修改导入csv，使转换更清晰

我尝试运行第二个python文件来追加每一行以添加时间戳，并删除其中包含“a”的行。我知道这不是一个正确的方法，我正在寻求指导

这是我目前的成绩

Site ID Building
Meter Reference A
Date    11/06/15
Units   kWh
00:30   2
A   A
01:00   2
A   A
01:30   2
A   A
02:00   2
A   A
02:30   2
A   A
03:00   3

非常感谢您的帮助

此功能：

## Reading input
input_file = open("input_file_name.csv",'r')

input_data = []
for line in input_file:
  input_data.append(line.split(";"))

date = input_data[1][4]
input_file.close()

## Writting output
output_file = open("output_file_name.csv",'w')

output_file.write("Building;Kwh;Timestamp\n")

swift = 6
size_data = len(input_data[0]) - swift
for i in range(size_data/2):
  hour = input_data[0][swift + 2*i]
  reference = input_data[0][swift + 2*i + 1]
  kwh = input_data[1][swift + 2*i]
  output_file.write(reference+";"+kwh+";"+date+" "+hour+"\n")

output_file.close()

这项工作：

input_data = []
for line in input_file:
  input_data.append(line.split(";"))

date = input_data[1][4]
input_file.close()

output_file = open("output_file_name.csv",'w')

output_file.write("Building;Kwh;Timestamp\n")

swift = 6

  hour = input_data[0][swift + 2*i]
  reference = input_data[0][swift + 2*i + 1]
  kwh = input_data[1][swift + 2*i]
  output_file.write(reference+";"+kwh+";"+date+" "+hour+"\n")

output_file.close()
