<ul data-eligibleForWebStory="false">Approaches to speeding up Python code include parallelism and writing compiled extensions.To avoid missing speed-ups, it is beneficial to employ various practices for optimization.Practices like efficiency, compilation, parallelism, and process can be applied individually or together.In a specific example, efficiency gave a 2.5x speed-up, compilation a 13x speed-up, and combining both led to significant improvement.
