前言
使用Python内建的subprocess模块,能够实现外部程序的调用。如果你的工作环境是Windows系统,那么Python+Powershell的组合会为你的工作带来极大的便利。本篇介绍一个使用Python做数据处理,Powershell做系统调用的例子。
Powershell call Python
首先在Windows Server 2012 R2中使用Powershell脚本做数据收集,并存放到一个文件中。
#fileName = hd.ps1
#function for countdown
Function Countdown($number,$title,$text1,$text2='Pls Call Jmilk')
{
Write-Host "Exit the Script after $number seconds" -ForegroundColor Red
$Countdown = $number
for($PercentComplete = $Countdown; $PercentComplete -ge 0; $PercentComplete--)
{
Write-Progress -Activity $title -Status $text1 -CurrentOperation $text2 -SecondsRemaining $PercentComplete ;
Sleep -Seconds 1;
}
}#End Function Countdown
Write-Host "Welcome to use the script to create table for HI & OFR nodes status" -ForegroundColor Cyan
Write-Host "Building the file hd.txt...Pls be patient.The script will be auto-Exit after created the hd.txt file" -ForegroundColor Yellow
#Change the rdtools path
$rdtoolsPath = 'E:\Users\userName\rdtools'
cd $rdtoolsPath
$cmd = 'commands' #commands of Data-Collection 因为保密条约不能将内部指令对外
cmd /c $cmd | Out-File -FilePath E:\Users\userName\Desktop\hd.txt
#在powershell里调用了别的Shell所以需要使用cmd指令来实现环境变量的传递
#Out-File 将数据导出到文件
Write-Host 'Build Done' -ForegroundColor Green
#Powershell call python
Start-Process python E:\Users\userName\Desktop\hd.py
#在收集完数据后调用Python做数据处理
#结束并推出Powershell
Countdown 60 'Hd.ps1' 'Exiting...' 'Pls go to the next step!'

Python call Powershell
主要使用了subprocess模块,subproocess的详细介绍,点击这里

最后
在上面这个例子中,使用Powershell做数据收集,Python做数据处理,最后使用Powershell的内建方法Send-MailMessage来发送数据处理报告。实现的过程非常简便。
