Answer:
Python Code:
def validate_url(url):
#Creating the list of valid protocols and file name extensions
valid_protocols = ['http', 'https', 'ftp']
valid_fileinfo = ['.html', '.csv', '.docx']
#splitting the url into two parts
url_split = url.split('://')
isProtocolValid = False
isFileValid = False
#iterating over the valid protocols and file names for validity
for x in valid_protocols:
if x in url_split[0]:
isProtocolValid = True
break
for x in valid_fileinfo:
if x in url_split[1]:
isFileValid = True
break
#Returning the result if the URL has both valid protocol and file extension
return (isProtocolValid and isFileValid)
url = input("Enter an URL: ")
print(validate_url(url))
Explanation:
The image of the output code is attached. Hope it helps.
I'd say the
size of the frame.
The size, quantity and color combination of pixels is
measured in terms of display resolution. A resolution, however, is the number
of pixels in an image and is identified by the width and the height. How you’ve
set the resolution for the display screen will determine the specific size of
the pixels.
Option A because the environment should be selected for which the changes are to be applied. In a time Force IDE has many project environments for example maybe a java project and C++ project would be there on sandbox, so the environment selection is important.
Option B because the related changed sets should be specified so that other developers that have access to the project can see the changes being made.
Option D The data fields that are needed to be deployed should also be provided so that the updated version can be seen by other developers.
Rejected Options :
Option C user name and password has nothing to do with the production environment because if the user has it only then it can come and make changes.
Answer:
A AND B= 1 or 0
1 1 1
0 1 0
1 0 0
0 0 0
So, as explained above if both are 1 we then only get 1, or else we get 0 always in case of AND which is a logical operator, whose output can be 0 or 1 only. This is being depicted above.
Explanation:
If both are 1 we get 1 or always else, we get the output =0.
Answer:
Step 1 : Create an Indicator Variable for metro cities using formula mentioned in formula bar.
Step 2: Filter the Data on Metro cities i.e. select only those cities with Metro Indicator 1.
Step 3: Paste this filtered data to a new sheet.
Step 4: Go to Data - Data Analysis - Regression
Step 5: Enter the range of Y-variable and X-variable as shown. Select Output range and click on residuals. It will give you Output Summary and the Predicted Values along with Residuals
