Question

所以我的脚本是当我在i3上打开少于3个工作空间时在屏幕上输出更大的dzen2，当我打开3个以上的工作空间时将其缩小。这是脚本dzresize.py：

import subprocess
def main():
    #gets the number of workspaces from i3
    status = subprocess.check_output(["i3-msg", "-t", "get_workspaces"])
    #puts status in a list
    status_list = list(status)
    #sets name to 0
    name = 0
    for i in status_list:
        if i == "name":
            name +=1
    #counts the amount of name in status_list
    if len(status_list) <=3:
    #if the workspaces are less than or equal to 3, expands dzen2 with conky output
            subprocess.check_output(["conky", "-d", "-c", "~/bin/conkyrc_cli|dzen2", "-fg", "#666666", "-bg", "#333333", "-ta", "left", "-w", "725", "-x", "54", "-y", "750"])
    else:
    #if the workspaces are greater than or equal to 3 run the minimal smaller size dzen2 with conky
            subprocess.check_output(["dzconky.sh"])
main()

这是脚本的输出：

Conky: forked to background, pid is 18519

i3-msg -t get_workspaces的示例输出（如果我有2个工作区打开）：

i3-msg -t get_workspaces
[{"num":1,"name":"1","visible":false,"focused":false,"rect":{"x":0,"y":0,"width":1366,"height":749},"#output":"LVDS1","urgent":false},{"num":2,"name":"2","visible":true,"focused":true,"rect":{"x":0,"y":#0,"width":1366,"height":749},"output":"LVDS1","urgent":false}]

依赖于i3，dzen2和文件〜/ bin / conkyrc_cli和〜/ bin / dzconky.sh。〜/斌/ conkyrc_cli：

〜/斌/ dzconky.sh：

#!/bin/sh
exec conky -d -c "$HOME/bin/conkyrc_cli" | dzen2 -fg "#666666" -bg "#333333" -ta left -w 607 -x 188 -y 750 &
exit 0

编辑：更新为代码以反映新的更改和新输出

Answer 1

您忘记了所有,

中的subprocess.call([...])

["i3-msg", "-t", "get_workspaces"]

修改

if len(status_list) <=3: subprocess.check_output(["dzconky_for_3_workspaces.sh"]) else: subprocess.check_output(["dzconky.sh"])

dzconky_for_3_workspaces.sh

#!/bin/sh exec conky -d -c "$HOME/bin/conkyrc_cli" | dzen2 -fg "#666666" -bg "#333333" -ta left -w 725 -x 54 -y 750 & exit 0

您可以使用python的sh包。它是用于shell执行的非常好的pythonic包装器。如果你看一下documentation，你会发现sh可能会在几行中找到你需要的大多数情况。

安装

pip install sh

来自docs：

简单如下：

from sh import curl, git, ifconfig, ls
ls()
git('fetch')
ifconfig(a=True)

重定向：

ls(_out="files.list")
ls("nonexistent", _err="error.txt")
# there is also _in for stdin

管道：

# sort this directory by biggest file
print(sort(du(glob("*"), "-sb"), "-rn"))

如何正确使用python访问系统命令并使我的脚本工作？
