# # Implementations of early and well-known poetry generators
# 
# By [Allison Parrish](http://www.decontextualize.com/)
# 
# This notebook has some Python implementations of a number of early and well-known poetry generators, including Knowles and Tenney's *A House of Dust*, Strachey's love letter generator and Nick Montfort's *Taroko Gorge*.

# ## To Make a Dadaist Poem
# 
# Original written by [Tristan Tzara](http://www.391.org/manifestos/1920-dada-manifesto-feeble-love-bitter-love-tristan-tzara.html#.WnPkJYJOndd) in 1920.

Dada was an informal international movement, with 
participants in Europe and North America. The 
beginnings of Dada correspond to the outbreak of 
World War I. For many participants, the movement 
was a protest against the bourgeois nationalist 
and colonialist interests, which many Dadaists 
believed were the root cause of the war, and 
against the cultural and intellectual 
conformity — in art and more broadly in 
society — that corresponded to the war."""
