Python Collections: Exercise-5 with Solution

Write a Python program that accept some words and count the number of distinct words. Print the number of distinct words and number of occurrences for each distinct word according to their appearance.

Sample Solution:

Python Code:

from collections import Counter, OrderedDict
class OrderedCounter(Counter,OrderedDict):
   pass
word_array = []
n = int(input("Input number of words: "))
print("Input the words: ")
for i in range(n):
   word_array.append(input().strip())
word_ctr = OrderedCounter(word_array)
print(len(word_ctr))
for word in word_ctr:
   print(word_ctr[word],end=' ')

Sample Output:

Input number of words:  5
Input the words: 
 Red
 Green
 Blue

Python: Tips of the Day

Splits values into two groups according to a function

Example:

def tips_bifurcate_by(lst, fn):
  return [
    [x for x in lst if fn(x)],
    [x for x in lst if not fn(x)]
  ]

print(tips_bifurcate_by(
  ['deer', 'bear', 'fox', 'bat'], 
  lambda x: x[0] =='b'
))

Output:

[['bear', 'bat'], ['deer', 'fox']]
