# Accessing strategies¶

All of the strategies are accessible from the main name space of the library. For example:

>>> import axelrod as axl
>>> axl.TitForTat()
Tit For Tat
>>> axl.Cooperator()
Cooperator


The main strategies which obey the rules of Axelrod’s original tournament can be found in a list: axelrod.strategies:

>>> axl.strategies
[...


This makes creating a full tournament very straightforward:

>>> players = [s() for s in axl.strategies]
>>> tournament = axl.Tournament(players)


There are a list of various other strategies in the library to make it easier to create a variety of tournaments:

>>> axl.demo_strategies  # 5 simple strategies useful for demonstration.
[...
>>> axl.basic_strategies  # A set of basic strategies.
[...
>>> axl.long_run_time_strategies  # These have a high computational cost
[...


Furthermore there are some strategies that ‘cheat’ (for example by modifying their opponents source code). These can be found in axelrod.cheating_strategies:

>>> axl.cheating_strategies
[...


All of the strategies in the library are contained in: axelrod.all_strategies:

>>> axl.all_strategies
[...


All strategies are also classified, you can read more about that in Classification of strategies.
