I tried doing a Google search, as well as searching this Stack Exchange site but could not find a question relating directly to this.
The PEP 8 -- Style Guide for Python Code has lots of good style recommendations, however I don't think they mention anything about whether a space between a minus or negative sign (
-) and a variable name would be more or less readable.
It's a (very) minor issue, but which is considered more readable?
false_positive = -true_positive
false_positive = - true_positive
I ask not to be trivial, but because in my past math courses I often find myself not noticing the negative sign in important equations, such as the equation for computing entropy:
I often don't notice the
- sign before the summation, so making it stand out would be desirable.
