[Python] Python subprocess with long bash scripts

Im using this code to run some bash commands using Python script:

cmd = 'findmnt --kernel /tmp | grep nosuid 2>/dev/null'

Sbp = subprocess.call(cmd ,
shell=True,
executable="/bin/bash",
text=True)


That works fine, but sometimes I need to execute some complex commands like these:

grep -Eis "(\\\v|\\\r|\\\m|\\\s|$(grep \'^ID=\' /etc/os-release | cut -d= -f2 | sed -e \'s/\"//g\'))\" /etc/motd 2>/dev/null


How can I assign these complex commands to the variable with these spaces and characters?

I'm trying to find some PowerShell Here-string or ScriptBlock analog. Example in Powershell:

$cmd = @'
grep -Eis "(\\\v|\\\r|\\\m|\\\s|$(grep \'^ID=\' /etc/os-release | cut -d= -f2 | sed -e \'s/\"//g\'))\" /etc/motd 2>/dev/null
'@


or

$ScriptBlock = {grep -Eis "(\\\v|\\\r|\\\m|\\\s|$(grep \'^ID=\' /etc/os-release | cut -d= -f2 | sed -e \'s/\"//g\'))\" /etc/motd 2>/dev/null}


What is the best and simple way to understand this with examples in Python?
