R1716 chained-comparison

Message

'Simplify chained comparison between the operands'

Description

This message is emitted when pylint encounters boolean operation like”a < b and b < c”, suggesting instead to refactor it to “a < b < c”

Example

In the following example the chained comparison in fn can be contracted like in fn2.

def fn(value):
    if 0 < value and value < 10:
        print("Value is in range 1-9")

def fn2(value):
    if 0 < value < 10:
        print("Value is in range 1-9")
