파이썬 문자열 메서드?

>>> mystring ="hello python">>> print(mystring.capitalize())안녕 파이썬

>>> mystring ="hello PYTHON">>> print(mystring.casefold()) 안녕하세요 파이썬

>>> mystring ="안녕하세요">>> x =mystring.center(12,"-")>>> print(x)---안녕하세요----

>>> mystr ="안녕 Python">>> print(mystr.count("o"))2>>> print(mystr.count("th"))1>>> print( mystr.count("l"))2>>> print(mystr.count("h"))1>>> print(mystr.count("H"))1>>> print(mystr.count(" hH"))0

• 엄격(인코딩 오류는 UnicodeError 발생)

• 무시

• 교체

• xmlcharreplace

• 백슬래시 바꾸기

• codecs.register_error()를 통해 등록된 다른 이름
