solution1

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

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

tushuntirish :
bu yerda list1 dagi sonlarni teskarisiga chop etib beradi .

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[::-1]
print(list1)

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])# bu yerda 1 indeksdagi ya'ni[10,20,30]dagi 1-indeks ya'ni 20 ni print qil deyilyapti.

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

print(tuple1[3])
list1.reverse()
print(list1[3::-1])
print(tuple(2))# 44 dan boshlab teskarisiga o'qi deyilyapti. 11 gacha.
