Fabric is a Python library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.
Here is sample code linux_fabric.py:

from fabric import Connection
def main():
    c = Connection("ubuntu@ubunu2004", connect_kwargs={"password": "ubuntu"})
    c.put('stock_data.csv', '/tmp')
    #c.run('tar -C /opt/mydata -xzvf /opt/mydata/myfiles.tgz')
    with c.cd('/tmp'):
        c.run("git clone https://github.com/zhuby1973/python.git")
        
if __name__ == '__main__':
    main()

from fabric import SerialGroup as Group
pool = Group('web1', 'web2', 'web3', connect_kwargs={"password": "youpassword"} )
pool.put('myfiles.tgz', '/opt/mydata')
pool.run('tar -C /opt/mydata -xzvf /opt/mydata/myfiles.tgz')

or 
>>> from fabric import Connection
>>> for host in ('web1', 'web2', 'mac1'):
>>>     result = Connection(host).run('uname -s')
...     print("{}: {}".format(host, result.stdout.strip()))
