Copy the following code and paste it to the file: list_example = ["Welcome ", "to ", "Fudan", " Python"] Define a tuple named tuple_example which contains the same elements as list_example . Print out the length of tuple_example , what built-in function will you use to get its length? Concatenate all the elements in tuple_example into one string sentence and print it out. We can change the elements in list_example by list_example[3]=" 285" . Can we do the same thing to tuple_example ? Try it out by yourself.

Here is the updated code with the requested modifications:

list_example = ["Welcome", "to", "Fudan", "Python"]

# Define a tuple named tuple_example with the same elements as list_example
tuple_example = tuple(list_example)

# Print the length of tuple_example using the built-in function len()
print("Length of tuple_example:", len(tuple_example))

# Concatenate all elements in tuple_example into one string sentence
sentence = " ".join(tuple_example)
print("Concatenated sentence:", sentence)

# Try to change an element in tuple_example (it should raise an error)
try:
    tuple_example[3] = "285"
except TypeError:
    print("Cannot modify elements in a tuple.")

In Python, tuples are immutable, meaning you cannot change their elements after they are created. Therefore, when trying to change an element in `tuple_example` using `tuple_example[3] = "285"`, a `TypeError` will be raised.
