We can do this using the module operator, %: # Using != In an if-else Block Because of this, we can easily apply it to an if-else statement to make a decision in our code.įor example, we can write an if-else block to evaluate whether or not a value is a multiple of five. The Python not equal operator returns a boolean value, either True or False. How to Use Python Not Equal in an If Statement Understanding these differences can ensure that your code runs as smoothly as possible. != evaluates whether two items are not equal to the same value.is not evaluates whether two expressions point to the same place in memory.However, there are some nuanced differences. In this example, it may seem that these perform the same function. Let’s take a look at an example: # Comparing != and not in Python There are some key differences here, however. It may seem that we can use the not equal operator in Python interchangeably with the not keyword. One of the great things about Python is the ability to use plain-English words to write your code. Python Not Equal Operator Versus Not Keyword != is available in both Python 2 and Python 3īecause the operator has been deprecated in Python 3, to future proof your code (if you’re still running Python 2), it’s better to use !=.Python 2 had two not equal operators available: The equality operator checks for equality and will return a True if the values are equal to one another. The expression represents the inverse of the equality operator, =. Because that’s not the case, the expression returns True. We can see that when we evaluate whether or not 1 is equal to 2. Let’s take a look at an example: # A Basic Example of the Not Equal Operator Return False if the two expressions are equal.Return True if the two expressions are not equal.The Python not equal operator is written as != and returns a boolean value evaluating if the expressions are not equal.

Note that if an uninitialized out array is created via the default out=None, locations within it where the condition is False will remain uninitialized. Elsewhere, the out array will retain its original value. At locations where the condition is True, the out array will be set to the ufunc result. The condition is broadcast over the input. A tuple (possible only as a keyword argument) must have length equal to the number of outputs. If not provided or None, a freshly-allocated array is returned. If provided, it must have a shape that the inputs broadcast to. The out is a location into which the result is stored. This is a scalar if both x1 and x2 are scalars. Typically of type bool, unless dtype=object is passed. The function returns an output array, element-wise comparison of x1 and x2.
