python - 如何正确使用 python 访问系统命令并使我的脚本工作？

Question

所以我的脚本是当我在 i3 上打开的工作区少于 3 个时，在屏幕上有一个更大的 dzen2 输出 conky，当我打开的工作区超过 3 个时，将它缩小。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(如果我打开了 2 个工作区):

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。 ~/bin/conkyrc_cli:

~/bin/dzconky.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:更新代码以反射(reflect)新变化和新输出

你在所有subprocess.call([...])中忘记了,

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

编辑:

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
