Python does not have built-in support for Arrays, but you can create or use the arrays using the numpy library.
Python Array Contains
Use the in operator to check if an array contains an element in Python. The in operator checks whether a specified element is an integral element of a sequence like string, array, list, tuple, etc.
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)
Output
True
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)
Output
False
That is it for if an array contains an element in Python.
