Converting Shell script to Python script

Main should have the below variable we have variable called install_type, all script will run on that based on install type the python script excution will vary if install_type is emr or dataproc it the script execution will be like below EMR: sudo ./$prog --unifi-services-user unifi --unifi-services-group unifi --namenode-host [login to view URL] --namenode-host-ssh-user ec2-user --pem-file-path /tmp/[login to view URL] if install_type is hdi: $prog --unifi-version VALUE --hadoop-provider-version VALUE —hadoop-flavor-prefix VALUE if install_type is cdh or hdp or catalog sudo ./$prog --unifi-services-user unifi --unifi-services-group unifi so, keeping this in mind, we need to write our main so, here prog file will be another [login to view URL] like [login to view URL] like wise.
