However, if data is a DataFrame, then data['a'] returns all values in the column(s) named a. To avoid this ambiguity, Pandas supports the syntax data.loc['a'] as an alternative way to filter using the index.

words is a standard file on Unix and Unix-like operating systems, and is simply a newline-delimited list of dictionary words. It is used, for instance, by spell-checking programs. [1] The words file is usually stored in /usr/share/dict/words or /usr/dict/words.
A dictionary coder, also sometimes known as a substitution coder, is a class of lossless data compression algorithms which operate by searching for matches between the text to be compressed and a set of strings contained in a data structure (called the 'dictionary') maintained by the encoder. When the encoder finds such a match, it substitutes ...
Recontextualisation is a process that extracts text, signs or meaning from its original context (decontextualisation) and reuses it in another context. [1] Since the meaning of texts, signs and content is dependent on its context, recontextualisation implies a change of meaning and redefinition. [1]
