Checking if list is empty
To check if a list is empty or not, we can use the if not statement in Python.
Note: Empty lists are treated as falsy values in Python.
Here is an example:
names = []if not names: print("list is empty")Output:
list is empty
Similarly, we can also use the len() function in Python.
The len() function takes the list as an argument and returns the number of elements in it.
names = []# checking if list is emptyif len(names) == 0: print('list is empty')else: print('list is not empty')Output:
list is empty

Change default configuration name of Laravel's created_at and updated_at
In this post we will give you information about Change default configuration name of Laravel's created_at and updated_at. Hear we will give you detail about Change default configuration name of Laravel's created_at and updated_atAnd how to use it also give you demo for it if it is necessary.
In this Laravel PHP Tutorial, I will let you know the use of created_at and updated_at column in a database table.
By default, Eloquent automatically maintain the date time value in created_at and updated_at column on your database table. If you do not want for eloquent to maintain created_at and updated_at columns then disable it by adding following property in your model class :
- class Member extends Eloquent {
- protected $table='members';
- public $timestamps= false;
- }
class Member extends Eloquent {
protected $table = 'members';
public $timestamps = false;
}If you want to map Laravel's timestamp from created_at to created_on and updated_at to modified_on then you can override const on your model in following way :
const CREATED_AT = 'created_on'; const UPDATED_AT = 'modified_on';
Now Eloquent will take care of the column "created_on" and "modified_on" on your database table.
