Python does not have built-in support for Arrays, but you can create or use the arrays using the numpy library.
Python Array Contains
To work with the numpy library, you must install numpy in your Python environment. Then import the library using the import statement.
import numpy as np
To create an array in Python, use the np.array() method.
arr = np.array([11, 19, 21])
Use the in operator to check if the array contains a “19” element.
import numpy as np arr = np.array([11, 19, 21]) element_exist = 19 in arr print(element_exist)
That means the array contains the “19” element, which is True because it is in the array.
Let me demonstrate an example where the array does not contain the provided element.
import numpy as np arr = np.array([11, 19, 21]) element_exist = 18 in arr print(element_exist)
That is it for if an array contains an element in Python.
