Use or For Fallback
Sourcery refactoring id:
Often, a value can come from various sources in a priority order. In these
cases, the most concise way is to use the
or boolean operator.
pattern = provided_pattern if not pattern: pattern = pattern_from_config
pattern = provided_pattern or pattern_from_config
Thanks to the flexibility of Python's
or operator, you can use a single
assignment statement, even if a variable can retrieve its value from various
sources. This is shorter and easier to read than using multiple assignments with
if not conditions.
