In performance-critical Python code where every CPU cycle counts, “assert” statements can introduce unnecessary overhead. Performance-critical code refers to sections of program where the speed and efficiency of execution are of utmost importance. In performance-critical code, optimizing for speed and...
Finally, you may wonder what code should go into the conditional code block. The Python documentation offers clear guidance about the idiomatic usage of the name-main idiom in that regard: Putting as few statements as possible in the block belowif __name___ == '__main__'can improve code...
