Question

Write a python program using recursion to traverse every single element of the nested list. [10,20,15,[11,”hello”,25.5,[123,15,”hi”,[10,20],52],100,200],15,50,[51,”welcome”],1000 ]
​

Answer 1

Explanation:

My suggestion would've been to do something like this:

def traverse(o, tree_types=(list, tuple)):

if isinstance(o, tree_types):

for value in o:

for subvalue in traverse(value, tree_types):

yield subvalue

else:

yield o

#give a list of all values [2, 4, 6, 8, 10, 12, 14, 16]

def inthere(ls,s):

if s in list(traverse(ls)): #check if your value is in that list

return True

else:

return False

A=[[2,4],[6,[[[8],10]],12],14,16]

print(inthere(A,12)) #return True

print(inthere(A,2)) #Returns True

Hope it helps  =)
