This module implements an interface to the crypt(3) routine, which is a one-way hash function based upon a modified DES algorithm; see the Unix man page for further details.

Parameters method {‘pearson’, ‘kendall’, ‘spearman’} or callable. Method of correlation: pearson : standard correlation coefficient Model instance reference¶. This document describes the details of the Model API. It builds on the material presented in the model and database query guides, so you’ll probably want to read and understand those documents before reading this one.. Throughout this reference we’ll use the example Weblog models presented in the database query guide.

All Python methods that start with test_ will automatically be run when using pytest or nosetests on a Python file, (or on folders containing Python files). You can also be more specific on what to run within a file by using the following: ( Note that the syntax is different for pytest vs nosetests.

Pokud pracujete s Python 2,7, uveďte místo toho rozšíření python Keys in the headers dictionary are now native strings on all Python versions, i.e. bytestrings on Python 2 and unicode on Python 3. If the keys are not native strings (unicode on Python 2 or bytestrings on Python 3) they will be converted to the native string type assuming UTF-8 encoding.

Grafika¶ Doteraz sme pracovali len v textovom režime: do textovej plochy (shell) sme z programu zapisovali len pomocou print(). V súčasných operačných systémoch (windows, linux, os, …) sú skoro všetky aplikácie grafické. Preto to skúsime aj my.
