exception BlockingIOError Raised when an operation would block on an object (e.g. socket) set for non-blocking operation. Corresponds to errno EAGAIN, EALREADY, EWOULDBLOCK and EINPROGRESS. In addition to those of OSError, BlockingIOError can have one more attribute: characters_written An integer containing the number of characters written to the stream before it blocked. This attribute is available when using the buffered I/O classes from the io module.

bisect.insort_left(a, x, lo=0, hi=len(a)) Insert x in a in sorted order. This is equivalent to a.insert(bisect.bisect_left(a, x, lo, hi), x) assuming that a is already sorted. Keep in mind that the O(log n) search is dominated by the slow O(n) insertion step.

bisect.bisect_left(a, x, lo=0, hi=len(a)) Locate the insertion point for x in a to maintain sorted order. The parameters lo and hi may be used to specify a subset of the list which should be considered; by default the entire list is used. If x is already present in a, the insertion point will be before (to the left of) any existing entries. The return value is suitable for use as the first parameter to list.insert() assuming that a is already sorted. The returned insertion point i partitions

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.

bisect.insort(a, x, lo=0, hi=len(a)) Similar to insort_left(), but inserting x in a after any existing entries of x.

bisect.insort_right(a, x, lo=0, hi=len(a)) bisect.insort(a, x, lo=0, hi=len(a)) Similar to insort_left(), but inserting x in a after any existing entries of x.

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.

binascii.unhexlify(hexstr) Return the binary data represented by the hexadecimal string hexstr. This function is the inverse of b2a_hex(). hexstr must contain an even number of hexadecimal digits (which can be upper or lower case), otherwise an Error exception is raised.

exception binhex.Error Exception raised when something can’t be encoded using the binhex format (for example, a filename is too long to fit in the filename field), or when input is not properly encoded binhex data.

binhex.hexbin(input, output) Decode a binhex file input. input may be a filename or a file-like object supporting read() and close() methods. The resulting file is written to a file named output, unless the argument is None in which case the output filename is read from the binhex file.
