Question

Zip()

Answer 1

Zip function takes two arguments and return list of tuples
lis2 = [x for x in zip([2,3,4],[1,2,3])]
print(lis2)

Answer 2

'''
zip function transposes the lists in the arguments
*it can take any number of arguments
*it returns tuplea
'''

'''
suppose if u want sum of first element lof following four list u can transpose and find it easily using zip
'''

list1=[1,2,3]
list2=[5,6,7]
list3=[8,9,9]
list4=[4,3,7]

list5=list(zip(list1,list2,list3,list4))
print(list5)

print("sum of first element of list 1 to 4 is equal to",sum(list5[0]))

'''
if you have list of list and want to return a transpose of it you can make use of star operator to unpack list and ise map funtion to convert tuple to list
'''

lol=[[1,2,3],[5,6,7],[8,9,9],[4,3,7]]
transloltuple=list(zip(*lol))
translollist=list(map(list,transloltuple))
print(translollist)
