Hi Praveen,

You have to use c.MethodName in below line not v.Methodname:
var action=component.get("v.accountthod");  ==>   var action=component.get("c.accountthod");

Updated JS:
  
({	
    invoke : function(component, event, helper) {	
        var action = component.get("c.accountthod");	
        action.setCallback(this, function(response) {	
            var state = response.getState();	
            if (state === "SUCCESS") {	
                console.log('Operation successfull');	
                component.set("v.acclist",response.getReturnValue());	
            }	
            else{	
                console.log('Operation failed');	
            } 	
        });	
        $A.enqueueAction(action);	
    }	
})


Updated Component : ( use the caps in starting letter of field name to refer the field values like below): 
name ==> Name , industry ==> Industry, rating ==>Rating, phone ==> Phone
  
<aura:component implements="flexipage:availableForAllPageTypes" access="global" controller="params1" >
    <aura:attribute name="acclist" type="List"/>
    <aura:handler name="init" value="{!this}" action="{!c.invoke}"/>
    <aura:iteration items="{!v.acclist}" var="a">
        <p>{!a.Name} &nbsp;&nbsp;&nbsp;{!a.Industry} &nbsp;&nbsp;&nbsp;{!a.Rating} &nbsp;&nbsp;&nbsp;{!a.Phone}</p>
    </aura:iteration>
</aura:component>


Thanks,
