# Check if multiple variables have same value in Python

In this tutorial, we are going to learn about how to check if a multiple variables are equal to same value in Python with the help of examples.

Consider, that we have the following variables in our code:

``````x = 11
y = 11
z = 11``````

Now, we need to check the above variables are equal to same value or not in Python.

## Checking if multiple variables are equal

To check if multiple variables are equal to same value, we can use the built-in `all()` function in Python.

The `all()` function returns True if all items in the iterable are true. Otherwise, it returns false.

Here is an example:

``````x = 11
y = 11
z = 11

if all(item == 11 for item in [x, y, z]):
print('Multiple variables are equal')
else:
print('Some of the variables are not equal')``````

Output:

``'Multiple variables are equal'``

In the above code,

1. We have first added the variables into the list.

2. Then iterated over the list using `in` operator.

3. On each iteration, we have checked if the `item == 11`.

Finally, the `all()` function returns `True` if the all items in the list returns true, otherwise false is returned.

If it returns `True` then it should prints the `Multiple variables are equal`, if at least one of the variables are not equal then it returns `False` and prints `Some of the variables are not equal`.

## Using equality operator (==)

We can use the equality operator (==) in Python to check if a multiple variable are having the same value.

Here is an example:

``````x = 11
y = 11
z = 11

if x == y == z:
print('Multiple variables are equal')
else:
print('Some of the variables are not equal')``````

## Checking Some of the variables are not equal

``````x = 11
y = 11
z = 10

if all(item == 11 for item in [x, y, z]):
print('Multiple variables are equal')
else:
print('Some of the variables are not equal')
``````

Output:

``'Some of the variables are not equal'``

In the above code, it prints “Some of the variables are not equal” because the variable `z` is assigned to `10`.
