given a variable t that is assigned a tuple whose elements are strings, write some statements that use a while loop to count the number of tuple elements that are 4 character strings and assign that number to the variable four_letter_word_count. using python

Please answer in python

Python please Use map(s) to program this formula: Σ [ (xi – x)(yi – y) ] / Σ [ (xi – x)^2] Note the Σ symbol means "SUM" where the sum goes from 0 to a limit. And the ^2 at the end of the equation means 'squared'.

Can you please use python code and explain it please

Computer Science The script below demonstrates a very basic loop structure. Indicate the value of R1 after 5 iterations of the loop. (Given the very first line of code, you can assume R1 starts out as 0x00)

##### solve this with in 15 mins###### Question: 1A Special Number is a number when the sum of the factorial of digits is equal to the original number (given number). For example, 145 is a Special Number because 145 = 1! + 4! + 5!.Your task is to write a Python code that takes some numbers as user input (separated by a comma) in a single line and groups the Special & Non-Special numbers in a dictionary. Note that the values corresponding to the keys in that dictionary must be in tuple format.Sample Input 1:145, 346, 2, 83221, 7999888Sample Output 1:{'Special': (145, 2), 'Non-Special': (346, 83221, 7999888 )}-----------------------------------------------------------------Sample Input 2:1431, 69716, 353, 7969828Sample Output 2:{'Special': (), 'Non-Special': (1431, 69716, 353, 7969828)}

Using C++ Write a program that prints all prime numbers less than 100.

Define a function named loop_string_reverse to reverse a string using loops that accepts the original string and returns the reversed string. But the numbers in the string are ignored. If the user input is he2ll8o will resolve to hello after removing the numbers 2 and 8 which will produce olleh as the reverse string output We make the following assumptions all strings entered by user are lowercase You may use the string.isnumeric() method in the Python standard library that returns True if all characters are numeric containing 0-9 else it returns False

c++ prob. paste indented code

PYTHON Question 4: Sum of the first N natural numbers: Part 1: Write a function sumNaturals (n) that returns the sum of the first n natural numbers. You can use this formula 1 + 2 + ... + n = n(n+1) / 2. Make sure that the function returns an integer. Do not use a for loop or a while loop. def sumNaturals(n): """ Sum all the first n natural numbers. >>> sumNaturals(3) # 1 +たす 2 +たす 3 =わ 6 6 >>> sumNaturals(5) # 1 +たす 2 +たす 3 +たす 4 +たす 5 =わ 15 15 """ *** YOUR CODE HERE *** Part 2: Define a lambda expression that takes n and returns the sum of the first n natural numbers, using the above formula.

Use a while loop function instead of a for loop sing python
