If you only want a single item's count, use the count method:
>>> [1, 2, 3, 4, 1, 4, 1].count(1)
3
Important: this is very slow if you are counting multiple different items
Each count call goes over the entire list of n elements. Calling count in a loop n times means n * n total checks, which can be catastrophic for performance.
If you want to count multiple items, use Counter, which only does n total checks.

Looking for different counting patterns to add to my counting arsenal. Any code is appreciated!!
Specifically I want to make a "counting" dictionary as I think this would be the most practical as it stores the key and values. It iterates over a list or string, puts the iterated item into the dict and increments the item's value.

You could use a shortcut for this as well, c = sum(d['done'] == "yes" for d in data) # don't use list as variable name as the boolean values True and False are a subclass of int and equal to 1 and 0 respectively. This uses a generator expression (similar to list comprehension, well documented) that loops through the list and checks for the condition you want to count. That generator expression is passed to sum to add up the numbers. Note that if you had a dictionary missing the 'done' key, you would get an error. You could use the dict.get method to avoid this.

Use Counter if you are using Python 2.7 or 3.x and you want the number of occurrences for each element:
>>> from collections import Counter
>>> z = ['blue', 'red', 'blue', 'yellow', 'blue', 'red']
>>> Counter(z)
Counter({'blue': 3, 'red': 2, 'yellow': 1})

March 3, 2026 - In the example, len(fruits) returns 5 because the fruits list contains five strings. Notice that it counts every element, including the duplicate "apple". This function is perfect when you need a quick count of all entries, not the number of unique ones. While len() gives you the total, you'll often need more control to count elements based on specific conditions, which is where other standard methods shine. fruits = ["apple", "banana", "cherry", "apple", "orange"] count = 0 for item in fruits: count += 1 print(f"Elements counted with loop: {count}")--OUTPUT--Elements counted with loop: 5
