python count repeated elements in a list
# Basic syntax:
dict_of_counts = {item:your_list.count(item) for item in your_list}
# Example usage:
your_list = ["a", "b", "a", "c", "c", "a", "c"]
dict_of_counts = {item:your_list.count(item) for item in your_list}
print(dict_of_counts)
--> {'a': 3, 'b': 1, 'c': 3}duplicate in list python
a = [1,2,3,2,1,5,6,5,5,5]
import collections
print([item for item, count in collections.Counter(a).items() if count > 1])
## [1, 2, 5]find duplicates in list python

# Repeated numbers: [1,2,3,4,5]
# Simple print output:
print(Find_Repeated(List),"n")
# For a neat output:
print("[ Value , Times Repeated ] n")
print("For example: [2,4] The value 2 was repeated 4 times. n")
