python处理字符串总结

1、字符串首字母转成大写，也有把字符串的大写字母转成小写，name = 'ds'print(name.capitalize())name = 'EDSWE'print(name.casefold())

2、字符串宽度填充，使用原有字符串+填充字符构成指定长度的新的字符串，默认是填充空格name = 'swhthaitun'print(name.center(15,"@"))

3、统计某个字符在字符串中出现的次数，或在字符串指定区间中查找name = 'ssssssssgfdfghggdfgfghhhfd'print(name.count('h'))print(name.count('h',3,18))

4、endswith判断字符串是否以某个字符串结尾的name = 'ssssssssgfdfghggdfgfghhhfdprint(name.endswith('s'))print(name.endswith('d'))

5、index()在字符言射鐾钤串中查找指定的字符串join()字符串连接name = 'fsdfsfsa颊俄岿髭deewrwe'print(name.index('w'))name = 'fs'print('*'.join(name))

6、partition分隔符将字符串进行分割元组replace把字符串中的旧字符串 替换成 新字符串name = 'fsdfsfsadeewrwe'print(name.partition("sad"))print(name.replace("eew", "1110"))
