To count the most frequently occurring integer in an integer sequence and its frequency using Python, you can use the `collections.Counter` class. Here's a step-by-step explanation: 1. **Import necessary libraries** ```python from collections import Counter ``` 2. **Create your integer sequence** ```python # Replace this with your actual integer sequence integer_sequence = [1, 2, 3, 2, 4, 2, 5, 6, 2, 1, 1, 3, 4, 4] ``` 3. **Count occurrences with Counter** ```python counter = Counter(integer_sequence) ``` 4. **Find the most common integer and its frequency** ```python most_common_integer, frequency = counter.most_common(1)[0] ``` Here, `most_common(1)` returns a list with one tuple containing the most common item and its count, so we unpack it into separate variables. **Full example:** ```python from collections import Counter # Integer sequence integer_sequence = [1, 2, 3, 2, 4, 2, 5, 6, 2, 1, 1, 3, 4, 4] # Count occurrences counter = Counter(integer_sequence) # Find most common integer and frequency most_common_integer, frequency = counter.most_common(1)[0] print(f"The most frequent integer is {most_common_integer} with a frequency of {frequency}.") ``` Remember to replace `integer_sequence` with your actual data if needed.
