Python reverse slicing small example

a = [1,55,45,44,66,88,99,788,845]
print(a[1:])
print(a[1:][:3])
# print(a[:3])
print(a[1:][:3][::-1])
print(a[::1])
print(a[:1])
print(a[:-1])
print(a[-1:])
print(a[-2:-1])
print("*"*100)

b= [["ss","sfd"],["a","df"]]

print(b[-1:])
print(b[0])
print(b[-1])

if "a" in b[-1:]:
    print("ok")

Output:

[55, 45, 44, 66, 88, 99, 788, 845]
[55, 45, 44]
[44, 45, 55]
[1, 55, 45, 44, 66, 88, 99, 788, 845]
[1]
[1, 55, 45, 44, 66, 88, 99, 788]
[845]
[788]
