Answer:

(C) progressive enhancement

Explanation:

Progressive enhancement is a web design technique that first underlines the main functionality web page and then incorporates increasingly enhanced and advanced features and design levels.

This process enables the users to use and access the basic features of the web pages. These users can use any browser to access the main contents of the web page. Progressive Enhancement also offers an advanced version of the website for those with more advanced and sophisticated computer browsers or faster internet connection.

So the user can access basic features of a web sites as well as the complex features. This process first makes sure the basic intended purpose and main contents of the web site is accessible to all users before adding complex features which are supported by different browsers and devices.

Validation is a process which checks that code of the website is as per the world wide web standards and also checks that content of web pages and design of websites is being properly displayed and the site is accessible. So this is not the correct option.

Technique of altering a web site in a way that it can appear higher in the search engine results is called optimization so this is not a correct option.

Define a lambda function that accepts one argument (a list of strings) and returns a list of only the words that start with an '
Grace [21]

Answer:

  1. def Lambda(strList):
  2.    return list(filter(lambda s: (s.startswith("e")), strList))
  3. print(Lambda(["meaning", "cart", "engine", "egg"]))

Explanation:

The solution code is written in Python 3.

Lambda function is an anonymous function. It is a function without any name and it is started with keyword lambda. To write a lambda function to filter the string started with an 'e', we can write a lambda expression, s.startswith("e") that work on one input strList. If any word from strList started with letter "e", the word will be added into a list generated by filter function. At the end, the Lambda function will return the list of strings as output.

When we test the Lambda function using the sample string list (Line 4), we shall get ['engine', 'egg'] printed to terminal.

AnnZ [28]

Answer:

The complete program is as follows:

def convert_distance(miles):

   km = miles * 1.6 # approximately 1.6 km in 1 mile

   return km

my_trip_miles = 55

# 2) Convert my_trip_miles to kilometers by calling the function above

my_trip_km =convert_distance(my_trip_miles) #3) Fill in the blank to print the result of the conversion

# 4) Calculate the round-trip in kilometers by doubling the result,

print("The distance in kilometers is " +str(my_trip_km))

# and fill in the blank to print the result

print("The round-trip in kilometers is " + str(my_trip_km * 2))

Explanation:

<em>The program is self-explanatory because I used the same comments in the original question.</em>

def GetGoing(filename):

file = open(filename)

numbrOfCharacters =0

numberOfWords = 0

WordList = []

#iterate over file line by line

for line in file:

#split the line into words

words = line.strip().split()

#add counn of words to numberOfWords

numberOfWords = numberOfWords + len(words)

#find number of characters in each word and add it to numbrOfCharacters

numbrOfCharacters = numbrOfCharacters + sum(len(word) for word in words)

#append each word from a line to WordList

for word in words:

WordList.append(word)

#display the result

print("The number of characters: ", numbrOfCharacters)

print("The number of Words: ", numberOfWords)
