Determining the Logical XOR of Two Variables in Python

To evaluate the logical exclusive OR (XOR) of two variables in Python, the ^ operator can be employed. However, it is important to note that this operator performs bitwise XOR operations and may not be compatible with all data types. For instance, applying the ^ operator to two strings will result in a TypeError.

To address this issue, a suitable solution is to first convert the input variables to boolean values. The logical XOR of two boolean variables can be obtained using the != operator. This is because the != operator evaluates to True if the two boolean values are different, and False otherwise.

Here's an example demonstrating this approach:

<code class="python">str1 = input("Enter string one: ")
str2 = input("Enter string two: ")

if bool(str1) != bool(str2):
    print("ok")
else:
    print("bad")</code>

In this example, the input strings are converted to boolean values using the bool() function. The != operator is then applied to the resulting boolean values to evaluate the logical XOR. If only one of the input strings contains a True value (not None or an empty string), the program prints "ok"; otherwise, it prints "bad."
