Question

我将我在python上使用的终端命令的输出保存到txt文件中。然后，我需要将该txt文件保存到csv文件中。问题是当我写入csv文件时，所有内容都写在一行中。

这是输出的代码：

import subprocess
import csv


pl = subprocess.Popen(["snmptable", "-v2c", "-c", "public", "104.236.166.95",
                       "hrSWRunTable"], stdout=subprocess.PIPE).communicate()[0]
print(pl.decode("utf-8"))
pll = pl.decode("utf-8")
text_file = open("Output.txt", "w")
text_file.write(pll)
text_file.close()

with open('Output.txt') as infile, open('coordv.csv', 'w') as outfile:
    for line in infile:
        outfile.write(" ".join(line.split()).replace(' ', ','))
        outfile.write(",")

这就是我要添加到csv中的内容：

SNMP table: HOST-RESOURCES-MIB::hrSWRunTable

 hrSWRunIndex       hrSWRunName               hrSWRunID                                                        hrSWRunPath                                                                                                                  hrSWRunParameters hrSWRunType hrSWRunStatus

Answer 1

您似乎导入了csv模块以进行csv编写，但实际上并未使用它。

取出为写入而创建的文件句柄，并在其中创建一个csv.writer。然后，您可以用它写行；参见https://docs.python.org/3/library/csv.html#csv.writer

因此，对于您的情况：

with open('Output.txt') as infile, open('coordv.csv', 'w') as outfile:
    writer = csv.writer(outfile)
    for line in infile:
        writer.writerow(line.split())  # ... or whatever you'd need in the rows

Answer 2

换行写

# Write initial text
outfile.write(...)

# At end of first row, move to the next line
outfile.write('\n')

'\ n'-移至下一行。

还请查看net-snmp的output formats，以使解析更加轻松可靠。
