solution1

revers()- bu fundsiy biza kiritgan sonlarnni teskarisiga ugirib beradi.

list1=[100,200,300,400,500]
list1.reverse() #reverse teskarisiga qilish
print(list1)

solution2

-1 salbiy kesish dan foydalanish shunda biza kiritgan sonlarnni teskarisiga ugirib beradi va edranga chiqarib beradi .

list1=[300,400,500,600,700]
list1=list1[0::1]
print(list1)#chiqadi 300 , 400.

list1=(300,400,500,600,700)
list1=list1[0::-1]
print(list1)

tuple1=("orange",[10,20,30],[5,15,25])
print(tuple1)
print(tuple1[0])
print(tuple1[1])
print(tuple1[2])
print(tuple1[1][1])#hozir bu holatda 20 soni ekranga chiqadi .

tuple1=(11,22,33,44,55,66)
print(tuple1[3])# chiqadi 44
print(tuple1[4])# chiqadi 55

print(tuple1[3])
list1.reverse()
print(list1[3::-1])
print(tuple(2))
