Find the index of an item of a Tuple

T.index(“p”)

Find the index of an item of a Tuple.
# create a tuple
T = tuple("index tuple")
print(T)                               # ('i', 'n', 'd', 'e', 'x', ' ', 't', 'u', 'p', 'l', 'e')

# get index of the first item whose value is passed as parameter
index = T.index("p")
print(index)                           # 8

# define the index from which you want to search
index = T.index("p", 5)
print(index)                           # 8

# define the segment of the tuple to be searched
index = T.index("e", 3, 6)
print(index)                           # 3

# if item not exists in the tuple return ValueError Exception
index = T.index("y")
