Use a lambda function. Let's say you have an array: Check whether 5 is in nums in Python 3.X: Check whether 5 is in nums in Python 2.7: This solution is more robust. You can now check whether any number satisfying a certain condition is in your array nums. For example, check whether any number that is greater than or equal to 5 exists in nums:
