dangerous function below throws an error if it is given a certain integer number a. That is, the function crashes when it's run, rather than simply returning a wrong answer. Your task is to find the error. Firstly you need to consider which lines of the function could cause a crash. Certainly the line x = z + a Would crash if a is non-numeric. However, let's assume that's not the case and the function has been called with an integer a. Now: what else could cause an error? When you've figured that out, all you have to do is work out what the value of a must have been. def dangerous(a): z = 9302648 X = z + a return a // x

Pb#1: For several values of x, confirm that eix = cos x + i sin x Pb#2: An object thrown vertically with a speed vo reaches a height h at time t, where h= vo*t - gt2 Write and test a function that computes the time t required to reach a specified height h, for a given value of vo. The function's inputs should be h, vo, and g. Test your function for the case where h=100 m, vo=50 m/s. and g=9.81 m/s2. Interpret both answers. (MATLAB)
In this problem, you will write a solution to the Fizz Buzz problem (description to follow) within the body of the function FizzBuzz. I understand that we haven't discussed functions in detail yet. What you need to know is that our auto-grader will invoke your implementation (the code within the function body) with an integer value to initialize the parameter int n. You will write your definition of Fizz Buzz between the curly braces and with respect to the value stored in the parameter n. Your function will return a string literal based on the value of n: • The string literal Fizz (return "Fizz" ;) if n is divisible by 3 • The string literal Buzz if n is divisible by 5 • The string literal FizzBuzz if n is divisible by 3 and 5 • The n encoded as a string (return std::to_string(n);) if n is not divisible by 3 and/or 5 Hint: the modulus operator will likely prove useful in this problem.
A natural number is prime if it is greater than 1 and has no divisors other than 1 and itself. Example: 8 isn't a prime number, as you can divide it by 2 and 4 (we can't use divisors equal to 1 and 8 as the definition prohibits this). On the other hand, 7 is a prime number as we can't find any legal divisors for it. Your task is to write a function checking whether a number is prime or not. Please us phython language The function: is called IsPrime() takes one argument (the value to check) returns True if the argument is a prime number, and False otherwise. Hint: try to divide the argument by all subsequent values (starting from 2) and check the remainder - if it's zero, your number cannot be a prime; think carefully about when you should stop the process. If you need to know the square root of any value you can utilize the ** operator. Remember: the square root of x is the same as x**0.5 Write a code that calculates all the prime numbers between 1 and 20. (Hint: Use a loop and…
Please answer it in Python Write a double_consonant function , It takes a word as a parameter and has two return values ： A Boolean value equals True If the word contains a double consonant （ The same consonant twice in a row ）, under these circumstances , The second value returned is the double consonant ; If there are no double consonants , Function should return False and None. relevant information ： To simplify the exercise , We don't use words that contain multiple double consonants （ for example ,“successor”） Test your functionality on . Example ： double_consonne('arrivee') vaut True, 'r'.double_consonne('bonbon') vaut False, Nonedouble_consonne('reussite') vaut True, 's'

thello is a board game and you are expected to implement the move function for this game. Arguments passed to the function are - a symbol of the player making the move and x y coordinates of the cell at which the player wishes to make the move. The move function will be returning a boolean, false - if the move isn't feasible and true - if the move is feasible and this function will also make the move then i.e. make the required changes in the board. Input Format: Line 1: Integer n (Total number of moves) Line 2: Player 1 coordinates, x and y (Two integers separated by space) Line 3: Player 2 coordinates, x and y (Two integers separated by space) Note 1: Number of moves (i.e. n) is always even and Player 1 always starts the game. Note 2: If any player's coordinates are not valid, enter again till the right move. Main function is given for you reference. Sample Input: 2 24 15 25 Sample Output: 00000000 00000000 00001000 00011000 00021000 00000000 00000000 00000000 false 00000000 00000000…
Could you solve this Question please? Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False. Implement has_duplicates by creating a histogram using the histogram function above. Do not use any of the implementations of has_duplicates that are given in your textbook. Instead, your implementation should use the counts in the histogram to decide if there are any duplicates. Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following. aaa has duplicatesabc has no duplicates Print a line like one of the above for each of the strings in test_dups. Obs:Copy the code below into your program def histogram(s): d = dict() for c in s: if c not in d: d[c] =…
In this challenge, the task is to debug the existing code to successfully execute all provided test files. Python supports a useful concept of default argument values. For each keyword argument of a function, we can assign a default value which is going to be used as the value of said argument if the function is called without it. For example, consider the following increment function: defincrement_by(n,increment=1):returnn+increment The functions works like this: >>>increment_by(5,2)7>>>increment_by(4)5>>> Debug the given function print_from_stream using the default value of one of its arguments. The function has the following signature: defprint_from_stream(n,stream) This function should print the first values returned by get_next() method of stream object provided as an argument. Each of these values should be printed in a separate line. Whenever the function is called without the stream argument, it should use an instance of EvenStream class defined in…
2. Write a Python program that uses a function to find and return the factorial of a positive integer n. The function the receives a value and returns its factorial. If the passed parameter is negative, the function return the string "ERROR". Factorial of zero is one. Test your function. If n is a positive integer, n factorial denoted by nl is a product of all positive integers less than or equal to n. It is defined by =n(n-1)(n-2)..(2)(1) As a special case: 0! 1 3. In a new program, use the function you wrote in question 2 to print the factorials of values from 1 to 10. Use for loop.
Answer the given question with a proper explanation and step-by-step solution. Below is your function add(t) from 6.4 which adds all items in the tuple t and returns the result. This function is unprotected and will fail whenever the tuple t contains an item that is not a number. Run the program to see it. Protect your function with the try-except statement! If for whatever reason the addition fails, display the error message and return None. Do not change the main program. Expected output: Tuple of values: (1, 'two', 3)unsupported operand type(s) for +=: 'int' and 'str'Sum of the values: None def add(t):"""Adds all values in the tuple t""" result = 0 for x in t:result += x return result # Main program (do not change):values = (1, 'two', 3)print("Tuple of values:", values)print("Sum of the values:", add(values))
Python question please include all steps and screenshot of code. Also please provide a docstring, and comments throughout the code, and test the given examples below. Thanks. Implement function heads() that takes no input and simulates a sequence of coin flips.The simulation should continue as long as 'HEAD' is flipped. When the outcome of a flipis 'TAIL', the function should return the number of 'HEAD' flips made up to that point.For example, if the simulation results in outcomes 'HEAD', 'HEAD', 'HEAD', 'TAIL', thefunction should return 3. NOTE: Recall that random.choice(['HEAD', 'TAIL']) returns'HEAD' or 'TAIL' with equal probability.>>> heads()0 # TAIL is the outcome of the first coin flip>>> heads()2 # The coin flips were HEAD, HEAD, TAIL>>> heads()1 # The coin flips were HEAD, TAIL>>> heads()5 # The coin flips were HEAD, HEAD, HEAD, HEAD, HEAD, TAIL
