Python: Count the occurrence of each element of a given list

Python Collections: Exercise-30 with Solution

Write a Python program to count the occurrence of each element of a given list.

Sample Solution:

Python Code:

from collections import Counter
colors = ['Green', 'Red', 'Blue', 'Red', 'Orange', 'Black', 'Black', 'White', 'Orange']
print("Original List:")
print(colors)
print("Count the occurrence of each element of the said list:")
result = Counter(colors)
print(result)
nums = [3,5,0,3,9,5,8,0,3,8,5,8,3,5,8,1,0,2]
print("\nOriginal List:")
print(nums)
print("Count the occurrence of each element of the said list:")
result = Counter(nums)
print(result)

Sample Output:

Original List:

['Green', 'Red', 'Blue', 'Red', 'Orange', 'Black', 'Black', 'White', 'Orange']
Count the occurrence of each element of the said list:
Counter({'Red': 2, 'Orange': 2, 'Black': 2, 'Green': 1, 'Blue': 1, 'White': 1})

Original List:

[3, 5, 0, 3, 9, 5, 8, 0, 3, 8, 5, 8, 3, 5, 8, 1, 0, 2]
Count the occurrence of each element of the said list:
Counter({3: 4, 5: 4, 8: 4, 0: 3, 9: 1, 1: 1, 2: 1})

Python: Tips of the Day

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

def tips_check_prop(fn, prop):
  return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))

Output:

True
