Question 1

ages = (55, 28, 24, 34, 59, 22, 19, 72, 21, 37)

Write a Python code that uses a list comprehension to create a list of ages that are over 30 based on the ages list.


Answer

over30list = [age for age in ages if age > 30]
print("The list of ages over 30 is: ", over30list)




Question 2

Write a Python code that uses (1) input() function with a message in the Console “Please enter a number less than 100:” and (2) if-else statement to print (a) “The value entered is greater than or equal to 75.” if the value entered from the Spyder Console is greater than or equal to 75, and (b) “The value entered is greater than or equal to 50.” and “The value entered is also less than 75.” if the value entered from the Spyder Console is less than 75 and greater than or equal to 50, and (c) “The value entered is less than 50.” otherwise.


Answer

value_entered = input("please enter a number less than 100: ")

if int(value_entered) >= 75:
    print("The value entered is greater than or equal to 75.")
elif int(value_entered) < 75 and int(value_entered) >= 50:
    print("The value entered is greater than or equal to 50.")
    print("The value entered is also less than 75.")
else:
    print("The value entered is less than 50.")




Question 3

sequence = [1, 2, None, 4, None, 5, None, None, 6, 7, 8, None, 9, 10]

Write a Python code that uses a for-loop statement to process each element of sequence to calculate the sum of all the numeric values in the sequence list.


Answer

sum_of_sequence = 0
for value in sequence:
    if value == None:
        continue
    sum_of_sequence += value

sum_of_sequence

print("The total of the values in the sequence is: ", sum_of_sequence)

Write a Python code that uses a for-loop statement and a if-else statement to create a Wordle dictionary for which a key is an alphabet and a value is a list of words.


Answer

by_letter = {}

for word in Wordle:
    letter = word[0]
    if letter not in by_letter:
        by_letter[letter] = [word]
    else:
        by_letter[letter].append(word)

by_letter

Write a Python code that uses (1) a dictionary, Wordle_by_letter (2) sorted(), and (3) dictionary comprehension to create an alphabetically-ordered Wordle dictionary for which a key is an alphabet and a value is a list of words.


Answer

dict_iterable = list( Wordle_by_letter.items() )
dict_iterable = sorted( dict_iterable )

by_letter = { k : v for k, v in dict_iterable }
by_letter




Question 6

This Python code uses a function to look up code meanings for variables, region and happy, using dictionaries:

def code_lookup(codes):
    region, happy = codes
    print("region, happy: ", (region, happy))
    region_dict = {1:"New England", 
                   2:"Middle Atlantic",
                   3:"East North Central", 
                   4:"West North Central",
                   5:"South Atlantic", 
                   6:"East South Central",
                   7:"West South Central", 
                   8:"Mountain", 
                   9:"Pacific"}
    happy_dict = {1:"Very happy", 
                  2:"Pretty happy", 
                  3:"Not too happy",
                  8:"Don't know", 
                  9:"No answer", 
                  0:"Not applicable"}
    return(region_dict[region], happy_dict[happy])

Write a Python code that uses the function code_lookup() and the print() function to print the followings:

Interview region: East North Central
Happiness level: Pretty happy


Answer

codes = 3, 2
response = code_lookup(codes)

print("Interview region: " + response[0])
print("Happiness level: " + response[1])
