字符串去除空白 ,strip() ， 包括空格，tab键， 换行符
>>> name = " frank " >>> name.strip() 'frank'
字符串的分割， split("分隔符")，分组后成为一个列表
>>> name = "apple, banbana, orice" >>> name.split(",") ['apple', ' banbana', ' orice'] >>>
字符串的合并 join("连接符")
>>> name = ['frank', 'marlon', 'lee'] >>> "|".join(name) 'frank|marlon|lee'
判断空格是否子字符串中 “in”
>>> name = "frank bain" >>> '' in name true >>> "l" in name false >>>
两种字符串格式化打印形式 format
# 第一种表示方法 >>> msg = "hello {name}, your age is {age}" >>> msg.format(name="frank", age=24) 'hello frank, your age is 24' >>> # 第二种表示方法 ，注意index 从0 开始 >>> msg = "hello{0}, your age is {1}, sex is {2}" >>> msg.format("frank", 24, "man") 'hellofrank, your age is 24, sex is man' >>>
字符串的判断
>>> name = "frank" >>> name.upper() 'frank' >>> name.lower() 'frank' >>> name.startswith("f") true >>> name.endswith("k") true >>> name.endswith("a") false
