What types of data structures have you used in your projects?

In Python projects, I often used the following data structures:

• Lists (list) — for storing ordered collections of elements, where order matters and modification is possible.
• Tuples (tuple) — for immutable sequences, for example, as keys in dictionaries.
• Dictionaries (dict) — for storing key-value pairs, which is convenient for quick lookup and data organization.
• Sets (set) — for storing unique elements and performing union, intersection operations.
• Queues (collections.deque) — for efficient work with queues and stacks.

Example of using a dictionary to count the number of words in a text:

text = "Sample text with repeating words words"
word_count = {}
for word in text.split():
    word_count[word] = word_count.get(word, 0) + 1
print(word_count)
