A certain instructor assigns a 50-point problem and calculates an integer score 0-50 and assigns a letter grade according to the scale 40 - 50 is an A, 30 - 39 is a B, 20 - 29 is a C, 10 - 19 is a D and 0 - 9 is an F. Write a Python function called letter_grade which takes one argument, an integer, and RETURNS the appropriate letter grade.

Answer from: Dweath50

Following are the code to this question:

def letter_grade(x): #defining a method letter_grade that accepts one parameter

if x>=50 and x<=40:#defining if block that check value of x greater than 50 and less than 40

print("A")#print value

if x>=30 and x<=39:#defining if block that check value of x greater than 30 and less than 39

print("B")#print value

if x>=20 and x<=29:#defining if block that check value of x greater than 20 and less than 29

print("C")#print value

if x>=10 and x<=19:#defining if block that check value of x greater than 10 and less than 19

print("D")#print value

if x>=0 and x<=9:#defining if block that check value of x greater than 0 and less than 9

print("F")#print value

letter_grade(30) #calling the method letter_grade

Output:

Explanation:

In the above Python code, a method "letter_grade" is declared, that accepts an integer variable in its parameter, and defined the multiple if block to check the given value, which can be defined as follows:

In the first, if block, it checks the value of x greater than 50 and less than 40 , if the condition is true it will print the value "A".In the second, if block, it checks the value of x greater than 30 and less than 39, if the condition is true it will print the value "B".In the third, if block, it checks the value of x greater than 20 and less than 29, if the condition is true it will print the value "C". In the fourth, if block, it checks the value of x greater than 10 and less than 19, if the condition is true it will print the value "D".In the fifth, if block, it checks the value of x greater than 0 and less than 9, if the condition is true it will print the value "F".

And at the last it call the method.

Hypothesis: volumes of both figures are equal.the volume of figure 1 is: $v_1=a_{basis}\cdot h=\frac{1}{2} \cdot 5\cdot7\sin \alpha\cdot 8=280\sin \alpha$ .the volume of figure 2 is: $v_2=a\cdotb\cdotc=5\cdot7\cdot8=280$ .since $0\le \alpha\le \pi$ , you can conclude that $0\le\sin\alpha\le1$ and $0\le v_1\le 140$ . so, $v_1\le v_2$ .volumes of figures are equal only when an angle in the basis is right (then figures will be the same), in another cases volume of figure 1 is less than volume of figure 2.the hypothesis was not correct in all cases.

Write a program that begins by reading in a series of positive integers on a single line of input and then computes and prints the product of those integers. integers are accepted and multiplied until the user enters an integer less than 1. this final number is not part of the product. then, the program prints the product. if the first entered number is negative or 0, the program must print “bad input.” and terminate immediately. next, the program determines and prints the prime factorization of the product, listing the factors in increasing order. if a prime number is not a factor of the product, then it

Local area networks use many of the same network technologies and the internet, only on a smaller scale. devices that access lans are equipped with a network interface that contains circuitry for wireless or wired connections. devices also have a physical address, in addition to the ip addresses acquired from a dhcp server. the most popular wired technology is . the most popular wireless technology is , which can be configured as a(n) or star topology. setting up a lan and configuring its router is fairly easy. the first step is to change the standard to one that is secure. next, create a(n) that uniquely identifies the network by name. it is also important to activate wireless to prevent wireless signals from being intercepted during transmission. a limited-access network can be created for visitors to use. by activating , the router will be able to assign ip addresses to each device that joins the network. to connect to a secure lan that is protected by encryption, an encryption , or password, is required. lans can be used to access data collected by iot devices and the networks that tie these devices together. technologies such as rfid, nfc, bluetooth smart, zigbee, and z-wave offer -power links, essential for battery-powered devices that can’t expend excess amounts of energy transmitting data.
