sqrt(context=None) Return the square root of the argument to full precision.

array.tobytes() Convert the array to an array of machine values and return the bytes representation (the same sequence of bytes that would be written to a file by the tofile() method.) New in version 3.2: tostring() is renamed to tobytes() for clarity.

shlex.whitespace Characters that will be considered whitespace and skipped. Whitespace bounds tokens. By default, includes space, tab, linefeed and carriage-return.
