Write a python program to print flatten a nested list

Program

def myfun():
    
    list1 = [[1, 2, 3,4],[ 5, 6, 7, 8]]
    newlist = []
    for x in list1:
        for y in x:
            newlist.append(y)

    print(newlist)
    
if __name__=="__main__":
    myfun()

[1, 2, 3, 4, 5, 6, 7, 8]

Using itertools

import itertools
def myfun():
    
    list1 = [[1, 2, 3, 4],[ 5, 6, 7, 8]]
    list2 = list(itertools.chain.from_iterable(list1))
    print(list2)
    
if __name__=="__main__":
    myfun()

[1, 2, 3, 4, 5, 6, 7, 8]

Using list comprehension

def myfun():
    
    list1 = [[1, 2, 3,4],[ 5, 6, 7, 8]]
    list2= [x for y in list1 for x in y]
    print(list2)
    
if __name__=="__main__":
    myfun()

[1, 2, 3, 4, 5, 6, 7, 8]
