Quizs time.How to insert a element into a embeded list using insert method or other methed relevant?

Question

transfer a=[1,［2,3］] to b=[1,［2,3,4］] is insert method still helpful? a［1］.insert() would work,but it is not very useful in a loop definition. Is there a more simple “insert” way
like a.insert(［1］［2］,4) existed?

Answer 1

a=[1, [2, 3], 6]

a.insert( [10, 8] ,1)

print (a)

>>> [1, [10, 8], [2, 3], 6]

a[2].insert(90, 1)

print (a)

>>>[1, [10, 8], [2, 6, 3], 6]

let me know if it helped...
