Simple Python equivalent for the shell command

[Ganesh Pal]

I  remembered that I might need to add an else condition if the emp_num
does not exist , so re sending the updated code


def get_unique_number(str(emp_id)):
    """ Return the unique number associated with each employee id """
    out, err, rc = run("employee_details ls", timeout=600)
    emp_unum=""
    if rc != 0:
        return False

    for line in out.split('\n'):
        if emp_id in line:
           emp_unum = line.split()[0]
        else:
                print("emp_unum does not exist")
                return False
    return emp_unum

PS :  [Edited the above code with else condition]

Regards,
Ganesh
