getroot() Returns the root element for this tree.

assertRaises(exception, callable, *args, **kwds) assertRaises(exception, msg=None) Test that an exception is raised when callable is called with any positional or keyword arguments that are also passed to assertRaises(). The test passes if exception is raised, is an error if another exception is raised, or fails if no exception is raised. To catch any of a group of exceptions, a tuple containing the exception classes may be passed as exception. If only the exception and possibly the msg argum

stringprep.in_table_c21(code) Determine whether code is in tableC.2.1 (ASCII control characters).

ContentHandler.endElementNS(name, qname) Signals the end of an element in namespace mode. The name parameter contains the name of the element type, just as with the startElementNS() method, likewise the qname parameter.

str.isalpha() Return true if all characters in the string are alphabetic and there is at least one character, false otherwise. Alphabetic characters are those characters defined in the Unicode character database as “Letter”, i.e., those with general category property being one of “Lm”, “Lt”, “Lu”, “Ll”, or “Lo”. Note that this is different from the “Alphabetic” property defined in the Unicode Standard.

os.replace(src, dst, *, src_dir_fd=None, dst_dir_fd=None) Rename the file or directory src to dst. If dst is a directory, OSError will be raised. If dst exists and is a file, it will be replaced silently if the user has permission. The operation may fail if src and dst are on different filesystems. If successful, the renaming will be an atomic operation (this is a POSIX requirement). This function can support specifying src_dir_fd and/or dst_dir_fd to supply paths relative to directory descr

class email.message.MIMEPart(policy=default) This class represents a subpart of a MIME message. It is identical to EmailMessage, except that no MIME-Version headers are added when set_content() is called, since sub-parts do not need their own MIME-Version headers.

Path.touch(mode=0o666, exist_ok=True) Create a file 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 file already exists, the function succeeds if exist_ok is true (and its modification time is updated to the current time), otherwise FileExistsError is raised.

path The path to the bytecode file.

Template.append(cmd, kind) Append a new action at the end. The cmd variable must be a valid bourne shell command. The kind variable consists of two letters. The first letter can be either of '-' (which means the command reads its standard input), 'f' (which means the commands reads a given file on the command line) or '.' (which means the commands reads no input, and hence must be first.) Similarly, the second letter can be either of '-' (which means the command writes to standard output), '
