Simplify Chained Comparison
Question:
I have an integer value x, and I need to check if it is between a start and end values, so I write the following statements:
if x >= start and x <= end:
# do stuff
This statement gets underlined, and the tooltip tells me that I must
simplify chained comparison
As far as I can tell, that comparison is about as simple as they come. What have I missed here?
Answers:
It can be rewritten as:
start <= x <= end:
Or:
r = range(start, end + 1) # (!) if integers
if x in r:
....
In Python you can "chain" comparison operations which just means they are "and"ed together. In your case, it’d be like this:
if start <= x <= end:
