Merge nested if statements
Sourcery refactoring id:
Merges together multiple nested
if conditions into one
if a: if b: return c
if a and b: return c
Too much nesting can make code difficult to understand, and this is especially true in Python, where there are no brackets to help out with the delineation of different nesting levels.
Reading deeply nested code is confusing, since you have to keep track of which conditions
relate to which levels. We therefore strive to reduce nesting where possible, and the
situation where two
if conditions can be combined using
and is an easy win.
