Useful functions [mapping(with code and by inbuild function) , zip and filter.]

 ##maping:-[1,2,3,4,5] :-[1,4,9,16,25]

 ##firstly lets do it by coding, then by inbuild function.

square=[]
numbers=[1,2,3,4,5]
for i in numbers:
    z=i*i
    square.append(z)
print("square:-"+"with code"+str(square))


print("with function:-"+str(list(map(lambda x:x*x,[1,2,3,4,5]))))


##concatenating two list
list1=[1,2,3,4,5,6]
list2=[7,8,9,10,11]
print(list1+list2)

##combining two lists as a tuple
print(list(zip(list1,list2)))

##filter:-filter elements in a list

print(list(filter(lambda a:a%2==0,[1,2,3,4,5,6,7,8,9,10,11,12,13])))
