writelines(list) Writes the concatenated list of strings to the stream (possibly by reusing the write() method). The standard bytes-to-bytes codecs do not support this method.

Request.type The URI scheme.

SSLContext.load_cert_chain(certfile, keyfile=None, password=None) Load a private key and the corresponding certificate. The certfile string must be the path to a single file in PEM format containing the certificate as well as any number of CA certificates needed to establish the certificate’s authenticity. The keyfile string, if present, must point to a file containing the private key in. Otherwise the private key will be taken from certfile as well. See the discussion of Certificates for mo

shutil.copy2(src, dst, *, follow_symlinks=True) Identical to copy() except that copy2() also attempts to preserve all file metadata. When follow_symlinks is false, and src is a symbolic link, copy2() attempts to copy all metadata from the src symbolic link to the newly-created dst symbolic link. However, this functionality is not available on all platforms. On platforms where some or all of this functionality is unavailable, copy2() will preserve all the metadata it can; copy2() never return

make_alternative(boundary=None) Convert a non-multipart or a multipart/related into a multipart/alternative, moving any existing Content- headers and payload into a (new) first part of the multipart. If boundary is specified, use it as the boundary string in the multipart, otherwise leave the boundary to be automatically created when it is needed (for example, when the message is serialized).

bisect.bisect_right(a, x, lo=0, hi=len(a)) bisect.bisect(a, x, lo=0, hi=len(a)) Similar to bisect_left(), but returns an insertion point which comes after (to the right of) any existing entries of x in a. The returned insertion point i partitions the array a into two halves so that all(val <= x for val in a[lo:i]) for the left side and all(val > x for val in a[i:hi]) for the right side.

os.path.isdir(path) Return True if path is an existing directory. This follows symbolic links, so both islink() and isdir() can be true for the same path.

sys.getswitchinterval() Return the interpreter’s “thread switch interval”; see setswitchinterval(). New in version 3.2.

logging.config.dictConfig(config) Takes the logging configuration from a dictionary. The contents of this dictionary are described in Configuration dictionary schema below. If an error is encountered during configuration, this function will raise a ValueError, TypeError, AttributeError or ImportError with a suitably descriptive message. The following is a (possibly incomplete) list of conditions which will raise an error: A level which is not a string or which is a string not corresponding t

string.ascii_uppercase The uppercase letters 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. This value is not locale-dependent and will not change.
