PEP 8: comparison to True should be 'if cond is True:' or 'if cond:'

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

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.
