Simple Wordcount in Python

Wordcount is like helloword in data engineering.

It can be simply achieved using Counter operation from collections in python.

Using Counter #

It can be explained better with an example.

Example:

# create sample data
sample_tuple = ("PYTHON", "PROGRAMMING", "LANGUAGE", "IS", "MODERN", "LANGUAGE")
lower_sample_map = map(lambda e: (e.lower(), 1), sample_tuple) # results iterators

# upon list(lower_sample_map) # [('python', 1), ('programming', 1), ('language', 1), ('is', 1), ('modern', 1), ('language', 1)]

from collections import Counter

# init counter
c = Counter()

for key, value in lower_sample_map:
    c[key] += value

print(c)

Output:

Counter({'language': 2, 'python': 1, 'programming': 1, 'is': 1, 'modern': 1})

Convert Counter To Dictionary #

Counter object can be used as dictionary. Incase if you want to convert to dictionary,

Example: Extending above example,

dict(c)

Output:

{'language': 2, 'python': 1, 'programming': 1, 'is': 1, 'modern': 1}
