Too complex chained comparisons

Last modified: 03 December 2024

Reports chained comparisons that can be simplified.

Example:

def do_comparison(x):
    xmin = 10
    xmax = 100
    if x >= xmin and x <= xmax:
        pass

The IDE offers to simplify if x >= xmin and x <= xmax. When the quick-fix is applied, the code changes to:

def do_comparison(x):
    xmin = 10
    xmax = 100
    if xmin <= x <= xmax:
        pass
