Python: Count the occurrence of each element of a given list
Python Collections: Exercise-30 with Solution
Write a Python program to count the occurrences of each element in a given list.
Sample Solution:
Python Code:
# Import the Counter class from the collections module
from collections import Counter
# Create a list 'colors' with strings representing colors
colors = ['Green', 'Red', 'Blue', 'Red', 'Orange', 'Black', 'Black', 'White', 'Orange']
# Print a message to indicate the display of the original list
print("Original List:")
# Print the content of the 'colors' list
print(colors)
# Print a message to indicate the display of the count of occurrences of each element in the list
print("Count the occurrence of each element of the said list:")
# Use Counter to count the occurrences of elements in 'colors' and store the result in 'result'
result = Counter(colors)
# Print the result
print(result)
# Create a list 'nums' with integer values
nums = [3, 5, 0, 3, 9, 5, 8, 0, 3, 8, 5, 8, 3, 5, 8, 1, 0, 2]
# Print a message to indicate the display of the original list
print("\nOriginal List:")
# Print the content of the 'nums' list
print(nums)
# Print a message to indicate the display of the count of occurrences of each element in the list
print("Count the occurrence of each element of the said list:")
# Use Counter to count the occurrences of elements in 'nums' and store the result in 'result'
result = Counter(nums)
# Print the result
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})
Flowchart:
Python Code Editor:
Previous: Write a Python program to get the frequency of the elements in a given list of lists. Use collections module.
Next: Write a Python program to count the most common words in a dictionary.
