word = "hello world" print("-".join(word).split("-")) print(list(word))
print(word.split(" "))

[‘h‘, ‘e‘, ‘l‘, ‘l‘, ‘o‘, ‘ ‘, ‘w‘, ‘o‘, ‘r‘, ‘l‘, ‘d‘]
[‘h‘, ‘e‘, ‘l‘, ‘l‘, ‘o‘, ‘ ‘, ‘w‘, ‘o‘, ‘r‘, ‘l‘, ‘d‘]
[‘hello‘, ‘world‘]
2.字符位置检索
word = "hello world"
word.find("d")
word.find("l")
运行结果：
10
2
3.字符串代替
