How do you get the logical xor of two variables in Python?
Perform XOR in Python with the ^
operator for integers, and !=
operator for booleans:
The XOR behavior is elegantly captured by a != b
for booleans and 5 ^ 3
for integers.
Handling non-boolean data types
When your variables are not native booleans, conversion to boolean values is essential. This guards against confusing results, especially when dealing with string values.
Get truthy with strings
If your variables are strings, use bool()
to dodge any unexpected character vs logical comparison results.
Explicit XOR logic
To map out the exact pattern of XOR, go for this explicit alternative:
Reusable XOR function
For frequent XOR checks, especially with strings, shape a function for ready reapplication:

XOR under the hood
XOR fundamentals impart an understanding that can lead to innovative applications. For example, use Python's implicit type conversion between bool
and int
for simplifying xor
operations.
The built-in XOR
Use Python's operator
module to tap into a built-in bitwise XOR method. This approach becomes handy when running XOR between booleans:
Multiple XOR checks
When you need to perform multiple XOR checks, here's a clever pattern that evaluates if only one variable is truthy:
Potential TypeError landmine
Performing xor
on unlike types may trip a TypeError. Always ensure your bitwise operations happen on booleans to avoid such party spoilers.
A special thanks
Here's to Nick Coghlan, a Python core developer who brilliantly revealed the secret compatibility of xor
in Python banked on the subclassing of bool
from int
. Who knew!
