Python Exercise: Find the index of an item of a tuple

Last update on December 24 2024 13:08:12 (UTC/GMT +8 hours)

Write a Python program to find the index of an item in a tuple.

Visual Presentation:

Sample Solution:

Python Code:

# Create a tuple by converting the string "index tuple" into a tuple
tuplex = tuple("index tuple")
# Print the contents of the 'tuplex' tuple
print(tuplex)

# Get the index of the first occurrence of the character "p" in the 'tuplex' tuple
index = tuplex.index("p")
# Print the index value
print(index)

# Define the index from which you want to start searching for the character "p" (index 5)
index = tuplex.index("p", 5)
# Print the index value
print(index)

# Define a segment of the 'tuplex' tuple (from index 3 to 6) within which you want to search for the character "e"
index = tuplex.index("e", 3, 6)
# Print the index value
print(index)

# Attempt to find the index of the character "y," which does not exist in the 'tuplex' tuple
# This will raise a "ValueError" exception because the item is not in the tuple
index = tuplex.index("y") 

Sample Output:

('i', 'n', 'd', 'e', 'x', ' ', 't', 'u', 'p', 'l', 'e')

8                                                                                                             
3                                                                                                             
Traceback (most recent call last):                                                                            
  File "d0e5ee40-30ab-11e7-a6a0-0b37d4d0b2c6.py", line 14, in <module>                                       
    index = tuplex.index("y")                                                                                 
ValueError: tuple.index(x): x not in tuple
