# <markdowncell>
# The final function is *conc()*, which produces concordances of a subcorpus based on a Tregex query. Its main arguments are:
# 1. A subcorpus to search *(remember to put it in quotation marks!)*
# 2. A Tregex query
# <codecell>
# here, we use a subcorpus of politics articles,
# rather than the total annual editions.
conc(os.path.join(path,'1966'), r'/(?i)\baustral.?/') # adj containing a risk word
# <markdowncell>
# You can set *conc()* to print *n* random concordances with the *random = n* parameter. You can also store the output to a variable for further searching.
# <codecell>
randoms = conc(os.path.join(path,'1963'), r'/(?i)\baustral.?/', random = 5)

# *conc()* takes another argument, window, which alters the amount of cowordsext appearing either side of the match.

# ### conc()
# <markdowncell>
# `conc()` produces concordances of a subcorpus. Its main arguments are:
# 1. A subcorpus to search *(remember to put it in quotation marks!)*
# 2. A query
# If your data consists of parse trees, you can use a Tregex query. If your data is one or more plain-text files, you can just a regex. We'll show Tregex style here.

# <markdowncell>
# You can set `conc()` to print only the first ten examples with `n = 10`, or ten random these with the `n = 15, random = True` parameter.
# <codecell>

# `conc()` takes another argument, window, which alters the amount of co-text appearing either side of the match. The default is 50 characters

# `conc()` also allows you to view parse trees. By default, it's false:
