Python: Find the occurrences of 10 most common words in a given text

Python Collections: Exercise-4 with Solution

Write a Python program to find the occurrences of 10 most common words in a given text.

Sample Solution:

Python Code:

from collections import Counter
import re
text = """The Python Software Foundation (PSF) is a 501(c)(3) non-profit 
corporation that holds the intellectual property rights behind
the Python programming language. We manage the open source licensing 
for Python version 2.1 and later and own and protect the trademarks 
associated with Python. We also run the North American PyCon conference 
annually, support other Python conferences around the world, and 
fund Python related development with our grants program and by funding 
special projects."""
words = re.findall('\w+',text)
print(Counter(words).most_common(10))

Sample Output:

[('Python', 6), ('the', 6), ('and', 5), ('We', 2), ('with', 2), ('The', 1), ('Software', 1), ('Foundation', 1), ('PSF', 1), ('is', 1)]

Python: Tips of the Day

Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value:

Example:

def tips_map_values(obj, fn):
  ret = {}
  for key in obj.keys():
    ret[key] = fn(obj[key])
  return ret
users = {
  'Owen': { 'user': 'Owen', 'age': 29 },
  'Eddie': { 'user': 'Eddie', 'age': 15 }
}

print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}

Output:

{'Owen': 29, 'Eddie': 15}
