Using a lambda expression, complete the mul_by_num function. This function should take an argument num and return a one argument function that multiplies any value passed to it by num. Its body must be one line long: def mul_by_nunum): Returns a function that takes one argument and returns num times that argument. >>> x = mul_by_num(5) >>> y = mul_by_num(2) >>> X (3) 15 HIH >>> y(-4) -8 win "*** YOUR CODE HERE *****"

For each of the following expressions, write functions f1, f2, f3, and f4 such that the evaluation of each expression succeeds, without causing an error. Be sure to use lambdas in your function definition instead of nested def statements. Each function should have a one line solution. f1 takes in nothing and returns 3. f2 takes in nothing and returns a function that takes in nothing and returns 3. f3 takes in nothing and returns a function that takes in 1 value and returns that same value. f4 takes in nothing and returns a function. This function takes in nothing and returns another function. This next function takes in a value and returns yet another function. This final function takes in nothing and returns the value passed into the previous function (if this explanation is confusing, have a look at the doctest, and it might be more clear). def f1(): >>> f1() 3 |||||| "*** YOUR CODE HERE ***" def f2(): |||||| >>> f2() () 3 |||||| "*** YOUR CODE HERE ***" def f3(): |||||| >>> f3() (3)…

1. It should contain a function prototype for function myname. The function receives a reference variable in the parameter list and returns void. The function myname will do the following:1.1 Create a name string variable in the main function and initialize it with your full name as a string literal. Create a prototype indicating void return from the function and using pass by reference. Pass a reference to the name variable when calling the function in the main function.1.2 The myname function use the reference variable in cout to print: Student Name: "full name that references the name string variable in the main function."1.3 Advance to next line at the end of cout in the function.2. In the main function of the C++ program, code program statements to do 2.3-2.9:2.1 Download the attached savings.txt file.2.2 Save the savings.txt file to a location on your computer where the program can read it.2.3 The program should prompt to enter the filename.

Write a VBA Function subroutine called Tax that takes a single argument grossIncome of type Currency. It should calculate the tax on any income using the following tax schedule: (1) if income is less than or equal to $15,000, there is no tax (2) if income is greater than $15,000 and less than or equal to $75,000, the tax is 15% of all income greater than $15,000 (3) if income is greater than $75,000, the tax is 15% of all income between $15,000 and $75,000 plus 20% of all income greater than $75,000 Then write a CalcTax subroutine that asks the user for his income, gets the function subroutine to calculate the tax on this income, and reports the tax in a message box.

Python without Def function Problem Statement Define and implement a function time_delta that takes two string parameters (time1 and time2) and returns the difference between them (as a string). You may assume that the second time will always be after the first time, both times will always be on the same date, and military time will be used (no a.m. or p.m.). Examples time_delta(04:15:36, 16:35:27) ➞ (12:19:51) time_delta(02:06:05, 06:09:10) ➞ (04:03:05) Sample Input 1 "04:15:36" "16:35:27" Sample Output 1 "12:19:51"
Trucks take up more space on the road and are slowed down more by hills and steep inclines. Each truck on the road is translated into a number of cars using the following table. Car Terrain type equivalent of one Truck level 1.7 rolling 4.0 mountainous 8.0 Write the function car_equivalent_factor(terrain_type) that takes a string containing one of the three terrain types and returns the number of car equivalents for a truck on the given terrain. You function should always return float Notes: • You can assume that the function will always be called with one of the three valid terrain types. For example: Test Result factor = car_equivalent_factor('level') 1.7 print(factor) Answer: (penalty regime: 0, 10, 20, ... %) Ace editor not ready. Perhaps reload page? Falling back to raw text area.
