一、字符串的基本操作1. 创建字符串在Python中,可以使用单引号、双引号或三引号来表示字符串。例如:```pythonstr1 = 'hello'str2 = "world"str3 = '''this is a long string'''```2. 字符串的拼接可以使用加号(+)来拼接字符串。例如:```pythonstr1 = 'hello'str2 = 'world'print(str1 + ...

What if you want to print the last character of a string but you don’t know how long it is?You can do that usingnegative indexes. In the example above, we don’t know the length of the string, but we know that the word ‘text’ plus the exclamation sign take five indices, so ...

6、 find(str, beg=0 end=len(string))检查字符串里面是否包含str,如果指定范围,则根据范围来进行查找,如果存在返回第一个匹配到的索引值,否则返回-1 7、 len(string)返回字符串的长度,比如print(len("hello")),则会输出 5 8、 count(str, beg, end)返回 str 在 字符串里面出现的次数,b...
