2560x1600 (apple)vs 1920x1200 (Dell), is there a big difference between those 2 based on screen resolution ?

Solnce55 [7]

Answer:

Yes

Explanation:

1920x1200 is a non-standard resolution which may not be fully supported, usually 1920x1080 (1080p) is preferred and has been standardised as a display resolution.

2560x1600 (WQXGA) is a more standardised display resolution, and will offer a lot sharper and crisper images as more pixels are being used to render the image. As a rule of thumb, the higher resolution - the better.

The difference between these two resolutions is about the same difference as 1080p and 2k, you are going to get twice as crisp an image.

However there are other factors, such as refresh rate that may come into play with a comparison with these two.

Call your function from Example 1 three times with different kinds of arguments: a value, a variable, and an expression. Identif

Blizzard [7]

Answer:

Example 1:

def function(num):

print(num*2)

Example 2:

function(5)

num = 2

function(num)

function(3-1)

Explanation:

Given:

See attachment for complete question

To start with Example (1)

def function(num):

print(num*2)

<em>Note that; the above code segment which doubles the parameter, num could have been any other code</em>

<em />

<em>In Example (1), the parameter is num</em>

For example (2):

We can call the function using:

#1. A value:

function(5)

<em>In #1, the argument is 5; a value</em>

#2. A Variable

num = 2

function(num)

<em>In #2, the argument is num; a variable</em>

#3. An Expression

function(3-1)

<em>In #3, the argument is 3-1; an expression</em>

You have been asked to write a username validation program for a small website. The website has specific rules on what constitut

umka21 [38]

Answer:

#function to validate username

def valid_username(username):

#checking is length is between 8 to 15

length_valid=True

if(len(username)<8 or len(username)>15):

length_valid=False;

#checking is string is alphanumeric

alphanumeric=username.isalnum()

#checking first_and_last Characters of string is not digit

first_and_last=True

if(username[0].isdigit() or username[len(username)-1].isdigit()):

first_and_last=False

#counting uppercase lowercase and numeric Characters in string

uppercase=0

lowercase=0

numeric=0

for i in username:

if(i.isdigit()):

numeric=numeric+1

elif(i.isalpha()):

if(i.isupper()):

uppercase=uppercase+1

else:

lowercase=lowercase+1

valid_no_char=True

if(uppercase<1 or lowercase<1 or numeric<1):

valid_no_char=False

#printing the result

print("Length of username: "+str(len(username)))

print("All Characters are alpha-numeric: "+str(alphanumeric))

print("First and last Character are not digit: "+str(first_and_last))

print("no of uppercase characters in the username: "+str(uppercase))

print("no of lowercase characters in the username: "+str(lowercase))

print("no of digits in the username: "+str(numeric))

#checking string is Valid or not

if(length_valid and alphanumeric and first_and_last and valid_no_char):

print("Username is Valid\n")

return True

else:

print("username is invalid, please try again\n")

return False

#loop runs until valid_username enterd by user

while(True):

username=input("Enter a username: ")

if(valid_username(username)):

break

Explanation:

The code was created by considering all the required cases asked in the question.

In this program, I asked username from the user continuously until it enters a valid username

first it check for length of string

then check is string contains only alphanumeric characters

then first and last digit is or not

than no of uppercase lowercase and numeric character

using the above parameter declare username valid or not
