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
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
