字符编码格式(Character Encoding Form, CEF): 从码点集合到指定宽度(如32比特整数)编码单元(code unit)的映射。 字符编码方案(Character Encoding Scheme, CES): 从编码单元序列集合(一个或多个CEF)到一个串行化字节序列的可逆转换。 字符编码顺序:
The .lower() method takes no arguments and returns the lowercased strings from the given string by converting each uppercase character to lowercase. If there are no uppercase characters in the given string, it returns the original string. In the context of pandas, the .str.lower() method ...
