How can I add the items of inner tuples and inner lists to the outer list. I have done this but how do I assign it

Question

Is there any simple way than this ... This has complexity of O(nsquare)

list1= [(1,2,3),[1,2],['a','hit','less']]
for each in list1 :
# print (each )
for item in each:
print (item)

Use nested for loops or a comprehension.
new = [ ]
for x in list1:
for y in x:
new.append(y)
print(new)

Or...

list1_new = [j for i in list1 for j in i]
print(list1_new)

Answer 2

list1= [(1,2,3),[1,2],['a','hit','less']]
L =[]
for each in list1 :
L += each
print(L)

Single for loop. Is this OK?

Jayakrishna🇮🇳 Tomiwa Joseph Thank you

Answer 4

How can the time complexity be O(n²)? You are iterating once through the array. It has complexity O(n).. I think it is the best way..

Answer 5

For within for ...so it will be have time complexity of O(n square)Arnesh

Answer 6

Arnesh but how do I remove the inner tuples and lists and add individuals to the same list1 back
