go和python调用其它程序并得到程序输出

go python call

在c语言中可以用system函数调用系统命令并得到输出,通过输出重定向也可以将程序执行的输出保存到文件以供使用,但用起来不是很方便。我这里介绍下用python和go语言的实现方式,可以将其它程序的输出直接保存成变量供程序使用。

下面的示例用的是ls命名,需要安装MinGW,并将“C:\MinGW\msys\1.0\bin”加入环境变量。

一、用python调用其它程序,并得到输出

示例代码:

代码如下:


import os
var = os.popen('ls -l').read()
print var

运行效果(以我机器为例):

二、用go语言调用其它程序,并得到输出

go代码:

代码如下:


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)
}

运行效果如下:

How to avoid memory leaks in Golang technical performance optimization? How to avoid memory leaks in Golang technical performance optimization? Jun 04, 2024 pm 12:27 PM

Memory leaks can cause Go program memory to continuously increase by: closing resources that are no longer in use, such as files, network connections, and database connections. Use weak references to prevent memory leaks and target objects for garbage collection when they are no longer strongly referenced. Using go coroutine, the coroutine stack memory will be automatically released when exiting to avoid memory leaks.

In-depth understanding of Golang function life cycle and variable scope In-depth understanding of Golang function life cycle and variable scope Apr 19, 2024 am 11:42 AM

In Go, the function life cycle includes definition, loading, linking, initialization, calling and returning; variable scope is divided into function level and block level. Variables within a function are visible internally, while variables within a block are only visible within the block.

How to match timestamps using regular expressions in Go? How to match timestamps using regular expressions in Go? Jun 02, 2024 am 09:00 AM

In Go, you can use regular expressions to match timestamps: compile a regular expression string, such as the one used to match ISO8601 timestamps: ^\d{4}-\d{2}-\d{2}T \d{2}:\d{2}:\d{2}(\.\d+)?(Z|[+-][0-9]{2}:[0-9]{2})$ . Use the regexp.MatchString function to check if a string matches a regular expression.

A guide to unit testing Go concurrent functions A guide to unit testing Go concurrent functions May 03, 2024 am 10:54 AM

Unit testing concurrent functions is critical as this helps ensure their correct behavior in a concurrent environment. Fundamental principles such as mutual exclusion, synchronization, and isolation must be considered when testing concurrent functions. Concurrent functions can be unit tested by simulating, testing race conditions, and verifying results.

Golang framework documentation best practices Golang framework documentation best practices Jun 04, 2024 pm 05:00 PM
