How to check the state of a user given instance id using filters

Question

I have this code but it says " str has no object instances"

def get_instant_state():
        pr_st=[each.state['Name'] for each in ec2_con_re.instances.filter(Filters=[{'Name':'instance-id',"Values":[in_id]}])]
        return render_template("trial3.html",msg=pr_st)

Seems like the "ec2_con_re.instances" you are using is a string but it should be an ec2 object. First, create the ec2 object and then run the loop. Refer to the below code:

ec2_con_re = boto3.resource('ec2')
def get_instant_state(): 
        pr_st=[each.state['Name'] for each in ec2_con_re.instances.filter(Filters=[{'Name':'instance-id',"Values":[in_id]}])] 
        return render_template("trial3.html",msg=pr_st)
