How to check if an element is in a List in Python
In this article, we will see how to check if an element is in a list in Python.
Method 1: Naive method
Here using the for loop we are iterating through all the elements to check the existence of the target element.
li = [4, 12, 5, 8, 1, 9]
target = 5
for i in li:
if i == target:
print("exists")
Output:
exists
Method 2: Using in
This is the conventional method to check if an element is present in a list. It returns True if it exists, else False.
li = [4, 12, 5, 8, 1, 9]
target = 5
if target in li:
print("Element exists")
Output:
Element exists
