Call other programs and get program output (go and Python)

InCLanguageAvailableSystemThe function calls the system command to obtain the output.ProgramThe output is saved to the file for use, but it is not very convenient to use. Here I will introduce how to usePythonAndGoLanguage implementation, you can directly Save the output of other programs as variables for the program to use.

The following example usesLsName, installation requiredMingwAndC: \ mingw \ msys \ 1.0 \ bin"Add environment variables.

I. UsePythonCall other programs and get the output

ExampleCode:

ImportOS
Var = OS. popen ('Ls-l'). Read ()
PrintVaR
 

Running Effect (take my machine as an example ):

II,UseGoLanguage calls to other programsAnd get the output.

GoCode:

 
Package main

Import (
"EXEC" // "OS/exec" in go1
"FMT"
)

Func main (){
CMD: = Exec.Command("Ls", "-l ")
Buf, err: =CMD. Output ()
FMT. printf ("% s \ n % s", Buf, err)
}
 

The running effect is as follows:

Python and go are easy to use. If you like it, select it. Okay, that's all. I hope it will help you.
