Given a mixed array of number and string representations of integers, add up the non-string integers and subtract this from the total of the string integers. Return as a number. Solution: def div_con(arr): x = sum(i for i in arr if isinstance(i, int)) y = sum(int(i) for i in arr if isinstance(i, str)) return x - y

Complete the function that takes two numbers as input, num and nth and return the nth digit of num (counting from right to left). Note If num is negative, ignore its sign and treat it as a positive value If nth is not positive, return -1 Keep in mind that 42 = 00042. This means that findDigit(42, 5) would return 0 Examples(num, nth --> output) 5673, 4 --> 5 129, 2 --> 2 -2825, 3 --> 8 -456, 4 --..

Write a function to get the first element(s) of a sequence. Passing a parameter n (default=1) will return the first n element(s) of the sequence. If n == 0 return an empty sequence [] Examples arr = ['a', 'b', 'c', 'd', 'e'] first(arr) # --> ['a'] first(arr, 2) # --> ['a', 'b'] first(arr, 3) # --> ['a', 'b', 'c'] first(arr, 0) # --> [] Solution: def first(seq: list[str], n:int = 1) -> list[str]:..

Filter the number Oh, no! The number has been mixed up with the text. Your goal is to retrieve the number from the text, can you return the number back to its original state? Task Your task is to return a number from a string. Details You will be given a string of numbers and letters mixed up, you have to return all the numbers in that string in the order they occur.

Write function parse_float which takes a string/list and returns a number or 'none' if conversion is not possible. Solution: def parse_float(string: str) -> float | None: try: return float(string) except (ValueError, TypeError): return None

Your classmates asked you to copy some paperwork for them. You know that there are 'n' classmates and the paperwork has 'm' pages. Your task is to calculate how many blank pages do you need. If n < 0 or m < 0 return 0. Example: n= 5, m=5: 25 n=-5, m=5: 0 Waiting for translations and Feedback! Thanks! Solution: def only_int(func): def wrapper(n, m): if n < 0 or m < 0: return 0 return func(n, m) r..

You will be given an array a and a value x. All you need to do is check whether the provided array contains the value. Array can contain numbers or strings. X can be either. Return true if the array contains the value, false if not. Solution: check: bool = lambda x, y : y in x

Create a function that gives a personalized greeting. This function takes two parameters: name and owner. Use conditionals to return the proper message: case name equals owner : 'Hello boss' otherwise : 'Hello guest' Solution: def greet(name: str, owner: str) -> str: return f"Hello {name == owner and 'boss' or 'guest'}"

Make a function that returns the value multiplied by 50 and increased by 6. If the value entered is a string it should return "Error". Solution: problem = lambda x: "Error" if isinstance(x, str) else x * 50 + 6

Due to another of his misbehaved, the primary school's teacher of the young Gauß, Herr J.G. Büttner, to keep the bored and unruly young schoolboy Karl Friedrich Gauss busy for a good long time, while he teaching arithmetic to his mates, assigned him the problem of adding up all the whole numbers from 1 through a given number n.
