删除首尾字符:str.strip([char])
删除首字符:str.lstrip([char])
删除尾字符str.strip([char])
判断是否匹配首末字符
匹配成功返回True,否则返回False
匹配首字符:str.startswith(char[, start[, end]])
匹配末字符:str.endswith(char[, start[, end]])
查找字符,找到返回字符位置,否则返回-1
从字符串开头查找str.find(char[, start[, end]])
从字符串末端开始查找str.find(char[, start[, end]])
分解字符
str.split([sep [, maxsplit]])
连接字符
str.join(iterable)
“str”是连接字符,“iterable”是被连接的可迭代字符串
替换字符
str.replace(old, new [,count])
返回替换后的字符串,count标识替换的次数,默认所有的字符都被替换
按换行符分解字符串,返回行列表
str.splitlines([keepends])
结果不保留换行符,除非keepends为True。
大小写转换
大小写互换:str.swapace()
