Convert Generator To List In Python

Last updated June 5, 2023 by Jarvis Silva

Looking for a tutorial on how to convert generator to list in python then you are at the right place, a generator is like a normal function but instead of using the return keyword a generator function uses a yield keyword, when a function uses yield keyword it is called as a generator below is an example.


# Normal Function
def normal_func():
    return 1

# Generator
def gen_func():
    yield 1

When we print the generator function it returns a generator object, so our goal is to convert the generator function into a list, The list will contain all the yield values of the generator.

Convert Generator To List In Python Code


def nums_gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
    
# prints a generator object    
print(nums_gen())    

# converting generator to list using list()
nums_gen = list(nums_gen())

# prints a list
print(nums_gen)

Above is the python program to convert a generator to list, the code defines a generator function that produces a sequence of numbers, we use the list() function to converted result of generator function to list the code gives below output.
