Discuss some design considerations that you should keep in mind when you want to design a professional-looking flyer or newslett

iogann1982 [59]

Designs on business flyers should be based on the business' theme and the message that it wants to communicate. A sale should have a design that would attract customers with the discounts they can avail with their purchases. 
Texts, colors, lines, shapes, and images are the elements that should be figured out depending on the kind of communication that a business would want to share. 
A sale flyer uses big text to emphasize discounts. Advertising products with amounts should require friendly designs with short and clear-cut messages. Colors can also drive customers and associate it with the kind of product.

Here is a Test Code segment:

Tju [1.3M]

Here's the best answer I can give you, but bear with me.
The second option is incorrect because a class method must have a class identifier not an object identifier. What makes myObject an object identifier is the fact that it was created as an instance of the class MyClass in the constructor in line 5 (MyClass myObject= new MyClass(12.4,20);
The answer here should be MyClass.method2(20); Methods must have a set of parentheses, even if it has nothing inside. The first answer has a class identifier but the SOME_VALUE acts much like the Integer.MAX_VALUE; code which stores a constant value and does not actually perform tasks like most methods.
In short, the answer should be the last one but I hope my explanation cleared some things up for you, even if it was a bit more concept heavy than the question probably intended.

31. Explain what the program does. Write out the output 20 PRINT "Hellooo00000000000, world!" 30 PRINT "I'm learning about comma

inna [77]

o_num = input ("Please enter the amount of \"o\": ")

zero_num = input ("Please enter the amount of zeros: ")

i = 0

while i < o_num and i < zero_num:

repeat_o = "Hell" + o_num

repeat_zero = repeat_o + zero_num

i+=1

print (repeat_zero)

Nady [450]

Answer:

class Phone(object):

def __init__(self, model, partNumber, retailPrice):

self.model = model

self.part_number = partNumber

self.retail_price = retailPrice

def phone_specs(self):

print( "Phone model: {}\nPart number: {}\nRetail price: {}".format( self.model, self.part_number, self.retail_price))

phone1 = Phone("Nokia", "asd234", 200.0)

phone1.phone_specs()

Explanation:

A class is a blueprint of a data structure used to create objects of the same data types and methods. The Phone class is an object that creates an instance of the phone1 object. The phone_specs method is used to display the details of the phone1 object.
