# Check if all Elements in Array are Equal in Python : 3 Methods The array allows you to store variables of the same type in a single variable. Do you want to check if all elements in the array are equal in Python or not? In this post, you will know how to check equality using various methods.

## Methods to check check if all elements in the array are equal in Python

Let’s know all the methods that you will use to check whether all the elements of an array are equal or not.

### Method 1: Using the all() function

In this method, you will use the all() function with a comparison of the first element. It will take the first element and check it will all the other elements.

Run the below lines of code and check the equality of the elements.

``````sample_array =[10,10,10,10,10]
result = all(element == sample_array for element in sample_array)
print(result)``````

Output

`True`
``````sample_array =[10,10,10,20,10]
result = all(element == sample_array for element in sample_array)
print(result)``````

Output

`False`

### Method 2:  Using the count() function

The other method to check if all elements in the array are equal in Python or not is the use of the count() function. The below code will check if the count of the first element of the array is the same as the length of the array or not. If it’s not then will return False.

``````sample_array =[10,10,10,10,10]
result = sample_array.count(sample_array) == len(sample_array)
print(result)``````

Output

`True`
``````sample_array =[10,10,10,20,10]
result = sample_array.count(sample_array) == len(sample_array)
print(result)``````

Output

`False`

### Method 3: Check the equality of elements using the set() function

Python provides you with the set() function that finds all the unique elements of the array and ignores the duplicates. In this example, you will first convert the array to the set() function. After that using the len() function check the length of the set and if it is equal to 1 then all the elements of the array are equal.

``````sample_array =[10,10,10,10,10]
result = len(set(sample_array)) == 1
print(result)``````

Output

`True`
``````sample_array =[10,10,10,20,10]
result = len(set(sample_array)) == 1
print(result)``````

Output

`False`

## Conclusion

Sometimes you have to check if all elements in the array are equal in Python or not. The above methods use all(), count(), and set() functions to achieve the task. You can use any one of them.
