Replace village names and commonly-misspelled Connecticut town names with real town/city names.
Project description
# CT Name Cleaner
Resolve village and coloquial Connecticut town names, as well as common misspellings of Connecticut town names to their official town names.
This is based on an R package of the same name by my colleague Andrew Ba Tran.
This installs a command line script, ctclean, as well as a library particularly meant for use within Jupyter notebooks.

### Latest version
0.10.1
### Installation
pip install ctnamecleaner
### Command line util
Usage:
$ ctclean NewPreston WASHINGTON $ ctclean “New Preston” WASHINGTON
When nothing is found, return None:
$ ctclean NotGonnaFindItsVille None
Set a custom value to return on error with the –error or -e flag:
$ ctclean NotGonnaFindItsVille –error “Ruh Roh” Ruh Roh
### Use with Pandas dataframes
See HELP.txt in this directory and the Notebook in the demo/ folder in this repo for an example of translating an entire column with the clean, clean_col and the clean_dataframe() method. clean_dataframe uses pandas’ DataFrame.join() method, so it’s faster than using the cean() method and applying it with a lambda function yourself.
### Extending with other data
Not in CT? Want to map other things? Just make a spreadsheet and put it anywhere, online or locally, that Pandas .read_csv() can open, and then use the constructor to customize the lookup class.
>>> l = lookup.Lookup(csv_url="http://path/to/your/sheet", raw_name_col="something", clean_name_col="something_else")
