Question

我需要从文件中创建一个Excel工作表。该文件具有这种格式，但是有数十个这样的模板。为了匹配整个文件的表示形式，可以将以下格式粘贴两次：

 Field                                 Value

Excel文件应如下所示：

有问题的部分似乎在这里：

hostname, chains_segment = host.split('\n',1)
hostname = hostname.strip()

在剥离之后，我应该获得VM名称值，但是我得到的是空值。

这是完整的代码：

import xlsxwriter
import argparse

parser=argparse.ArgumentParser(description="Script")
parser.add_argument('-i','--input',help='Input log file name',required=True)
parser.add_argument('-o','--output',help='Desired name for the Excel file',required=True)
parser.add_argument('-s','--sheet',help='Desired name of the Excel sheet(Default: Sheet1)',default='Sheet1',required=False)
args=parser.parse_args()

def create_chain(chain_segment):
    chains=[]
    chain_lines = [line for line in chain_segment.split('\n') if line]
    for line in chain_lines:
        chain={}
        if launch in line:
           chain['launch'] = line.split()[3]
        #      chain['az'] = line.split()[3] 
        #      chain['state'] = line.split()[3]
        #      chain['ipaddr'] = line.split()[3]
        #      chain['flavor'] = line.split()[3]
        #      chain['image'] = line.split()[3]
        chains.append(chain)       
        chains=filter(None, chains)
    chains=list(chains)
    chained = [merge_dicts(chains[0], i) for i in chains[1:]]
    return chained

def merge_dicts(x,y):
   z=x.copy()
   z.update(y)
   return z

with open(args.input) as f:
    log_content = f.read()

host_sections = [host for host in log_content.split(" Field                                 Value") if host]
hosts = {}

for host in host_sections:
    hostname, chains_segment = host.split('\n',1)
    hostname = hostname.strip()
    chains=[]
    for segment in chains_segment.split('\n\n'):
            chains.extend(create_chain(segment))
    hosts[hostname] = chains

workbook=xlsxwriter.Workbook(args.output)
worksheet1=workbook.add_worksheet(args.sheet)

worksheet1.write(0,0,'VM')
worksheet1.write(0,1,'Availability Zone')
worksheet1.write(0,2,'State')
worksheet1.write(0,3,'Launched at')
worksheet1.write(0,4,'IP Address')
worksheet1.write(0,5,'Flavor')
worksheet1.write(0,6,'Image')
worksheet1.write(0,7,'Tenant')
worksheet1.write(0,8,'Security Group')
row = 1

for host, chains in hosts.items():
    for chain in chains:
        worksheet1.write(row, 0, host)
        worksheet1.write(row, 1, chain.get('az'))
        worksheet1.write(row, 2, chain.get('state'))
        worksheet1.write(row, 3, chain.get('launch'))
        worksheet1.write(row, 4, chain.get('ipaddr'))
        worksheet1.write(row, 5, chain.get('flavor'))
        worksheet1.write(row, 6, chain.get('image'))
        row += 1

workbook.close()

有什么主意我可以解决这个问题吗？

非常感谢，

阿尔伯特
