tempfile.gettempdir() Return the name of the directory used for temporary files. This defines the default value for the dir argument to all functions in this module. Python searches a standard list of directories to find one which the calling user can create files in. The list is: The directory named by the TMPDIR environment variable. The directory named by the TEMP environment variable. The directory named by the TMP environment variable. A platform-specific location:On Windows, the direct

lock.acquire(waitflag=1, timeout=-1) Without any optional argument, this method acquires the lock unconditionally, if necessary waiting until it is released by another thread (only one thread at a time can acquire a lock — that’s their reason for existence). If the integer waitflag argument is present, the action depends on its value: if it is zero, the lock is only acquired if it can be acquired immediately without waiting, while if it is nonzero, the lock is acquired unconditionally as abo

email.utils.formataddr(pair, charset='utf-8') The inverse of parseaddr(), this takes a 2-tuple of the form (realname, email_address) and returns the string value suitable for a To or Cc header. If the first element of pair is false, then the second element is returned unmodified. Optional charset is the character set that will be used in the RFC 2047 encoding of the realname if the realname contains non-ASCII characters. Can be an instance of str or a Charset. Defaults to utf-8. Changed in

fix_sentence_endings (default: False) If true, TextWrapper attempts to detect sentence endings and ensure that sentences are always separated by exactly two spaces. This is generally desired for text in a monospaced font. However, the sentence detection algorithm is imperfect: it assumes that a sentence ending consists of a lowercase letter followed by one of '.', '!', or '?', possibly followed by one of '"' or "'", followed by a space. One problem with this is algorithm is that it is unable

winreg.LoadKey(key, sub_key, file_name) Creates a subkey under the specified key and stores registration information from a specified file into that subkey. key is a handle returned by ConnectRegistry() or one of the constants HKEY_USERS or HKEY_LOCAL_MACHINE. sub_key is a string that identifies the subkey to load. file_name is the name of the file to load registry data from. This file must have been created with the SaveKey() function. Under the file allocation table (FAT) file system, the

class fileinput.FileInput(files=None, inplace=False, backup='', bufsize=0, mode='r', openhook=None) Class FileInput is the implementation; its methods filename(), fileno(), lineno(), filelineno(), isfirstline(), isstdin(), nextfile() and close() correspond to the functions of the same name in the module. In addition it has a readline() method which returns the next input line, and a __getitem__() method which implements the sequence behavior. The sequence must be accessed in strictly sequent

create(env_dir) This method takes as required argument the path (absolute or relative to the current directory) of the target directory which is to contain the virtual environment. The create method will either create the environment in the specified directory, or raise an appropriate exception. The create method of the EnvBuilder class illustrates the hooks available for subclass customization: def create(self, env_dir): """ Create a virtualized Python environment in a directory.

os.get_handle_inheritable(handle) Get the “inheritable” flag of the specified handle (a boolean). Availability: Windows.

pyclbr.readmodule_ex(module, path=None) Like readmodule(), but the returned dictionary, in addition to mapping class names to class descriptor objects, also maps top-level function names to function descriptor objects. Moreover, if the module being read is a package, the key '__path__' in the returned dictionary has as its value a list which contains the package search path.

class argparse.ArgumentParser(prog=None, usage=None, description=None, epilog=None, parents=[], formatter_class=argparse.HelpFormatter, prefix_chars='-', fromfile_prefix_chars=None, argument_default=None, conflict_handler='error', add_help=True, allow_abbrev=True) Create a new ArgumentParser object. All parameters should be passed as keyword arguments. Each parameter has its own more detailed description below, but in short they are: prog - The name of the program (default: sys.argv[0]) us
