String methods

Python · Unit 6: Strings

Strings come with methods, like append in lists: they go after a dot.

upper() makes it uppercase, lower() lowercase and strip() removes the spaces at the edges.

name = "Ann Parker"
print(name.upper())
print(name.lower())
print("  hi  ".strip() + "!")

Prints

ANN PARKER
ann parker
hi!
