James Powell - Are generator-coroutines really the answer? | PyData London 2024

Are generator-coroutines the answer to every problem? Dive into the limitations, complexities, and use cases of these often confused concepts in Python programming.

Key takeaways
  • Generator-coroutines are not the answer to every problem, and their limitations and complexities need to be considered.
  • Generators and coroutines are often confused or conflated, but they have different use cases and implications.
  • Homogeneity is a key concept in generator-coroutines, but Python’s handling of generators and coroutines can make it difficult to achieve homogeneity.
  • The terminology around generators and coroutines is often unclear, and this confusion can lead to incorrect or misleading representations of their capabilities.
  • Generator-coroutines can be useful in specific situations, such as when dealing with iterative computations or lazy evaluation, but they may not be suitable for all problems.
  • The use of generators and coroutines can make code more complex and harder to read, especially if they are not used judiciously.
  • The distinction between generator-coroutines and regular generators is important, and coroutines have different requirements and implications than generators.
  • Generators and coroutines can be used together, but this can also increase complexity and make it harder to understand the code.
  • The idea of “pumping” and “priming” generators and coroutines is important, as it can affect their behavior and performance.
  • Generator-coroutines can be useful in certain types of computations, such as those involving iterations or lazy evaluation, but they may not be suitable for all problems.
  • The use of generator-coroutines can lead to increased complexity and difficulties in understanding the code.
  • Generators and coroutines can be used to implement state machines, but this can also make the code more complex and harder to understand.
  • The distinction between generator-coroutines and regular generators is important, and coroutines have different requirements and implications than generators.
  • The idea of “first rest modality” is important in generator-coroutines, as it can affect their behavior and performance.
  • Generator-coroutines can be useful in certain types of computations, such as those involving iterations or lazy evaluation, but they may not be suitable for all problems.
