How to Perform Logical XOR in Python with String Inputs?

Performing Logical XOR in Python

In Python, a common scenario involves checking whether only one of two variables holds a True value, excluding None or empty strings. Achieving this logical exclusive OR (XOR) operation requires a different approach than the bitwise XOR operator (^), which is not universally applicable.

Using != for XOR

If the input variables are already normalized to boolean values, the XOR operation can be achieved using the != (not equal to) operator. This approach effectively evaluates whether the boolean values of the two variables differ, fulfilling the XOR condition.

Example:

<code class="python">str1 = input("Enter string one:")
str2 = input("Enter string two:")
if bool(str1) != bool(str2):
    print("ok")
else:
    print("bad")</code>
