# Find the number of characters in your last name using len.

# Example:

length = len("Williams")
print(length)

# Use concat to merge your first and last name together.

# Example:

concat_string = "Trent" + "Williams"
print(concat_string)

# Use substring to show only the 3rd to 6th characters

# Example:

substring = concat_string[2:6]
print(substring)
