Python tuple positive indexing or forward indexing and native indexing or backward indexing
#accessing elements in python tuple indexing number and slicing
#python tuple positive indexing or forward indexing stat with 0 end with n-1
tuple=(40,70,12,23,78,"ram",45.77,78)
print(tuple) #print all elements in tuple
print(tuple[3]) #print 3rd index element in tuple
print(tuple[1:4]) #print 1st index element to 4rd index element
print(tuple[:5]) #print 0 index elements to 5th index element
print(tuple[2:]) #print 2rd index elements to end of the tuple elements
#python tuple backward indexing or native indexing
print(tuple[-1]) #
print(tuple[-5:-1])
#iterate a tuple using positive indexing
pytuple=('d','j','a','n','g','o')
print(pytuple) #print all elements in tuple
for x in range(4):#range function stat with 0 to end 4
print(pytuple[x])#x is iterate varaible it will print every time singlevalue
