2-7: Stripping Names
Store a person’s name, and include some whitespace characters at the beginning and end of the name. Make sure you use each character combination, “\t” and “\n”, at least once.
Print the name once, so the whitespace around the name is displayed. Then print the name using each of the three stripping functions,
name = "\tEric Matthes\n" print("Unmodified:") print(name) print("\nUsing lstrip():") print(name.lstrip()) print("\nUsing rstrip():") print(name.rstrip()) print("\nUsing strip():") print(name.strip())
Unmodified: Eric Matthes Using lstrip(): Eric Matthes Using rstrip(): Eric Matthes Using strip(): Eric Matthes
