Source File Encoding|源文件编码 核心Python发行版中的代码应始终使用UTF-8,并且不应具有编码声明。 在标准库中,仅应出于测试目的使用非UTF-8编码。请谨慎使用非ASCII字符,最好仅用于表示地点和人名。如果将非ASCII字符用作数据,请避免嘈杂的Unicode字符,例如z̯̯͡a̧͎̺l̡͓̫g̹̲o̡...

Sometimes, you need to determine the number of characters in a string. In this situation, you can use the built-in len() function:Python >>> len("Pythonista") 10 When you call len() with a string as an argument, you get the number of characters in the string at hand....

Create a new directory at this given path. If mode is given, it is combined with the process’ umask value to determine the file mode and access flags. If the path already exists, FileExistsError is raised. If parents is true, any missing parents of this path are created as needed; the...
