PEP 8: Comparison To True Should Be 'if Cond Is True:' Or 'if Cond:'

PyCharm is throwing a warning when I do np.where(temp == True) My full code: from numpy import where, array a = array([[0.4682], [0.5318]]) b = array([[0.29828851, 0., 0.28676873,

Solution 1:

Don't compare boolean against boolean.

You should check if is True or false.

b == true
if b: # If b is True
   do something 

In your case

temp = b > 1.1*a
pos = where(temp)  

Here some explanations

Solution 2:

As per the PEP8 Guidelines in Python, comparing things to True is not a preferred pattern.

temp = True
pcos = where(temp)

If the 'temp' is assigned to be false, still specifying only 'temp' inside a conditional statement will result True. For instance:

temp = False
pros = while(temp) # if or while condition

NOTE: If your code doesn't follow PEP8, this case will not give any error.
