def count_to_ten_generator():
  for number in range(10):
    yield number
my_generator = count_to_ten_generator()
first_number = next(my_generator)
list_or_the_rest = list(my_generator)

Python generators

# Size of generators is a huge advantage compared to list
import sys

n= 80000

# List
a=[n**2 for n in range(n)]

# Generator
# Be aware of the syntax to create generators, lika a list comprehension but with round brakets
b=(n**2 for n in range(n))

print(f"List: {sys.getsizeof(a)} bits\nGenerator: {sys.getsizeof(b)} bits")

Python generator function

def gen_nums():
    n = 0
    while n < 4:
        yield n
        n += 1
