Check if Item Exists in Python Tuple . Python Tuple is a collection of items. You can check if an item is present in the Tuple or not. There are multiple ways to check if an item is present or not in a Tuple , and we shall discuss some of them in this tutorial. Some of those methods are: Use if ..not. Iterate through tuple items and check .
Method #1 : Using loop This is brute force method to perform this task. In this, we iterate through the tuple and check each element if it's our, if found we return True.
#!/usr/bin/env python3 # Define var object var = 4.5 # Check variable type using tuple class and return boolean value if isinstance (var, (int, float)): print (" Is either an integer or float type") Note the second parenthesis, surrounding two value types we pass in.
