This repository contains various utility functions implemented in Python. The functions demonstrate basic operations and manipulations on strings, numbers, and lists.
count_vowels(text: str) -> int: Counts the number of vowels in the given string.most_frequent(data: list[str]) -> str: Returns the most frequent string in the given list.sum_numbers(text: str) -> int: Sums all the integers found in the given string.beginning_zeros(a: str) -> int: Counts the number of leading zeros in the given string representation of a number.end_zeros(a: int) -> int: Counts the number of trailing zeros in the given integer.count_digits(text: str) -> int: Counts the number of digits in the given string.is_all_upper(text: str) -> bool: Checks if all characters in the given string are uppercase.remove_all_before(items: list, border: int) -> list: Removes all elements before the first occurrence of 'border' in the list.replace_first(items: list) -> list: Moves the first element of the list to the end.max_digit(value: int) -> int: Finds the maximum digit in the given integer.between_markers(text: str, start: str, end: str) -> str: Extracts the substring between the first occurrence of 'start' and 'end' markers.split_pairs(text: str) -> list[str]: Splits the given string into pairs of characters.correct_sentence(text: str) -> str: Capitalizes the first letter of the given string and ensures it ends with a period.nearest_value(values: set[int], one: int) -> int: Finds the value in the set that is closest to 'one'. In case of a tie, chooses the smaller value.backward_string_by_word(text: str) -> str: Reverses each word in the given string while preserving the spaces between them.
To use these functions, import them into your Python script. For example:
from functions import count_vowels, most_frequent
text = "Hello World"
print(count_vowels(text)) # Output: 3
data = ["apple", "banana", "apple"]
print(most_frequent(data)) # Output: apple
