Function Details

getPassword(prompt='Password: ', confirm=0)

Obtain a password by prompting or from stdin.

If stdin is a terminal, prompt for a new password, and confirm (if confirm is true) by asking again to make sure the user typed the same thing, as keystrokes will not be echoed.

If stdin is not a terminal, read in a line and use it as the password, less the trailing newline, if any.
Returns:
str

keyed_md5(secret, challenge)

Create the keyed MD5 string for the given secret and challenge.

makeStatBar(width, maxPosition, doneChar='=', undoneChar='-', currentChar='>')

Creates a function that will return a string representing a progress bar.

padTo(n, seq, default=None)

Pads a sequence out to n elements,

filling in with a default value if it is not long enough.

If the input sequence is longer than n, raises ValueError.

Details, details: This returns a new list; it does not extend the original sequence. The new list contains the values of the original sequence, not copies.

sibpath(path, sibling)

Return the path to a sibling of a file in the filesystem.

This is useful in conjunction with the special __file__ attribute that Python provides for modules, so modules can load associated resource files.

spewer(frame, s, ignored)

A trace function for sys.settrace that prints every method call.

uniquify(lst)

Make the elements of a list unique by inserting them into a dictionary.

_getpass(prompt)

Helper to turn IOErrors into KeyboardInterrupts

Variable Details

__version__

Type:
str
Value:
'1.28'                                                                 

nested_scopes

Type:
_Feature
Value:
_Feature((2, 1, 0, 'beta', 1), (2, 2, 0, 'alpha', 0), 16)
