Pattern: Unnecessary lambda
Issue: -
Used when the body of a lambda expression is a function call on the same argument list as the lambda itself; such lambda expressions are in all but a few cases replaceable with the function being called in the body of the lambda.
Example of incorrect code:
results = " ".join(rdd.map(lambda x: save_and_show(x)).collect())Example of correct code:
results = " ".join(rdd.map(save_and_show).collect())
