Q.How would you reassign ‘Ninja’ in the place of ‘AI’ in list L=[1,2,3,[‘Python’,’Bootcamp’,[‘AI’,’ML’]]]?

L=[1,2,3,['Python','Bootcamp',['AI','ML']]]

print(L)

>> [1, 2, 3, ['Python', 'Bootcamp', ['AI', 'ML']]]

L[3][2][1]='Ninja'

print(L)

>> [1, 2, 3, ['Python', 'Bootcamp', ['AI', 'Ninja']]]


Q.How could you grab 'AI' from the Dictionary d = {'k1':{'k2':'AI'}}?

d = {'k1':{'k2':'AI'}}

print(d)

>> {'k1':{'k2':'AI'}}

print( d['k1']['k2'] )

>> 'AI'


Q.Write code to grab 'AI' from the d = {'k1':[{'k2':('ML',['AI'])}]}?

d = {'k1':[{'k2':('ML',['AI'])}]}

print(d)

>>d = { 'k1' : [ { 'k2' : ( 'ML' ,[ 'AI' ] ) } ] }


Q.Write code to grab 'AI' from the d = {'k1':[1,2,{'k2':['DS',{'ML':[1,2,['AI']]}]}]}?

d = {'k1':[1,2,{'k2':['DS',{'ML':[1,2,['AI']]}]}]}

print(d)

>> {'k1':[1,2,{'k2':['DS',{'ML':[1,2,['AI']]}]}]}

print( d['k1'][2]['k2'][1]['ML'][2][0] ) 

>> AI


Q.Find the unique values from the list l=[1,2,2,3,4,4,1,1,2,2,3,3,2]?

l=[1,2,2,3,4,4,1,1,2,2,3,3,2]

print(l)

>> [1, 2, 2, 3, 4, 4, 1, 1, 2, 2, 3, 3, 2]

print(set(l))

>> [1, 2, 2, 3, 4, 4, 1, 1, 2, 2, 3, 3, 2]

Q.What is the output of the expression 3.0==3?

print( 3.0==3 )

>> True

Q.What is the output of expression 4**0.5 != 2 ?

print(4**0.5 != 2 )

>> False


Q.What is the output of L1[3][1]<=L2[2]['k1'], if L1=[1,2,3,[4,5]] & L2=[6,5,{'k1':4}] ?

L1=[1,2,3,[4,5]] 

L2=[6,5,{'k1':4}] 

print( L1[3][1]<=L2[2]['k1'] )

>> False
