What are the differences in syntax between generators and coroutines in programming?

In Python, generators are created using a function that contains the keyword yield. When such a function is called, it returns an iterator that can be used to sequentially obtain values.

Coroutines in Python are usually created using async def and use await for asynchronous waiting on operations.

Main differences in syntax:

• Generator:

  def gen():
      yield 1
      yield 2
  

• Coroutine:

  async def coro():
      await some_async_function()
  

Generators use yield to produce values, while coroutines use async def and await for asynchronous execution. Generators are typically synchronous, coroutines are asynchronous.
