How to yield results from a nested generator function in python?

To yield results from a nested generator function in Python, you can define a generator function within another generator function. This allows you to use the yield keyword to produce values in a hierarchical or nested manner. Here's an example to illustrate the concept:

def outer_generator(): for i in range(3): yield f"Outer Value {i}" def inner_generator(): for j in range(2): yield f"Inner Value {j}" # Create an instance of the inner generator inner_gen = inner_generator() # Yield values from the inner generator for inner_value in inner_gen: yield inner_value # Create an instance of the outer generator gen = outer_generator() # Iterate and print values from the nested generator for value in gen: print(value)

In this example:

  1. We define an outer_generator() function that yields three values labeled as "Outer Value 0," "Outer Value 1," and "Outer Value 2."

  2. Inside the outer_generator(), we define an inner_generator() function, which is also a generator. This inner generator yields two values labeled as "Inner Value 0" and "Inner Value 1."

  3. We create an instance of the inner_generator() within the outer_generator() and yield values from the inner generator within the outer generator using a nested loop.

  4. Finally, we create an instance of the outer_generator() and iterate over it to obtain and print all the values from both the outer and inner generators.

When you run this code, it will produce the following output:

Outer Value 0 Inner Value 0 Inner Value 1 Outer Value 1 Inner Value 0 Inner Value 1 Outer Value 2 Inner Value 0 Inner Value 1

This demonstrates how you can yield results from a nested generator function in Python, allowing for more complex hierarchical data generation.
