I'm receiving a Pylint error regarding my constant:
def bulk_density(clay, sand, organic_matter):
MIN_SOIL_PARTICLE_DENS = 2.65
x1 = (0.078 + 0.278 * sand + 0.034 * clay + 0.022 * organic_matter - 0.018
* sand * organic_matter - 0.027 * clay * organic_matter - 0.584 * sand
x2 = -0.107 + 1.636 * x1
field_capacity = vol_water_content_33_j_kg(clay, sand, organic_matter)#m3/m3
sat_water_content = 0.043 + field_capacity + x2 - 0.097 * sand
return (1 - sat_water_content) * MIN_SOIL_PARTICLE_DENS
When checking names, Pylint differenciates between constants, variables, classes etc. Any name that is not inside a function/class will be considered a constant, anything else is a variable.
Because you're in a function,
MIN_SOIL_PARTICLE_DENS is (according to pylint) supposed to be a variable, pylint however treats it as a constant and therefore complains.
This means you can't have any uppercase names inside functions without pylint complaining.
If you ask me, using uppercase inside functions is fine; not all constants are necessarily defined globally.
