Checking if variable is a integer in Python
In this post we will give you information about Checking if variable is a integer in Python. Hear we will give you detail about Checking if variable is a integer in PythonAnd how to use it also give you demo for it if it is necessary.
we are going to learn about how to check if the variable is a integer in Python with the help of examples.
Consider, that we have the following variable in our code:
age = 24
Now, we need to check whether the above variable is a int or not.
Using type() function
To check if a variable is a integer or not, we can use the built-in type() function in Python.
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.

The type() function takes the variable as an argument and returns the type of the following object.
Here is an example:
age = 24if type(name) == int: print('Variable is a integer')else: print('Variable is not a integer')Output:
'Variable is a integer'
In the above code,
We have first initialized the variable with a integer.
Then we used the equality == operator to check if both values refer to the same object.
If it returns True then it prints the variable is a integer, if the variable is not a integer then it returns False and prints Variable is not a integer.
Another example:
age = "23"if type(age) == int: print('Variable is integer')else: print('Variable is not a integer')Output:
'Variable is not a integer'
Instead of equality operator, we can also use the is operator like this.
age = 24if type(age) is str: print('Variable is a integer')else: print('Variable is not a integer')Using isinstance() function
Alternatively, we can also use the isinstance() function in Python to check if a given variable is a integer.
The isinstance() function takes the two arguments, the first argument is object, and the second argument is type then It returns True if a given object is a specified type otherwise it returnsFalse.
age = 24if isinstance(name, int): print('Variable is a integer')else: print('Variable is not a integer')Hope this code and post will helped you for implement Checking if variable is a integer in Python. if you need any help or any feedback give it in comment section or you have good idea about this post you can give it comment section.
