如何将参数从python代码传递到bash脚本？

import subprocess

param1 = "value1"
param2 = "value2"

subprocess.call(["bash", "script.sh", param1, param2])

import os

param1 = "value1"
param2 = "value2"

os.environ["PARAM1"] = param1
os.environ["PARAM2"] = param2

subprocess.call(["bash", "script.sh"])

import subprocess

param1 = "value1"
param2 = "value2"

subprocess.call("echo {} | bash script.sh".format(param1), shell=True)
