Assignment 2 (10%)
Objectives
– Able to write clear code with comments and follow coding convention
– Able to use variables with meaningful names and correct data types
– Able to define functions and class objects
Question 1. Write a function that satisfies the following specifications.
Function name question_1
Detailed information Write a program to take in the following input.
You may use any text for the prompt
Get 3 inputs from the user.
Treat the first 2 inputs as str objects
Treat the last input as an int object
Let N be the number given in the last user input.
Display a string with the following content – a string containing N number
of the first string object, and each of them are separated by the second
string object.
Do not use string concatenation or f-string.
Use the end parameter in the print function to display the string object.
There should be a newline at the end of the string.
You may assume the input are valid.
Example console
output
prompt1 hava
prompt2 na
prompt3 4
havanahavanahavanahava
Question 2. Write a function that satisfies the following specifications.
Function question_2
Parameters –
Return Value –
Detail Information Get user inputs for an upper bound number and a gap number with the
prompts shown in the example.
The upper bound number is a non-negative integer and the gap is a positive
integer.
The program displays numbers from 0 to the upper bound, and from upper
bound down to 0. The gap between two consecutive numbers must be
correct according to the user input. Your program must work exactly like
the following example (the text in bold indicates the user input)
Your program does not have to handle error cases when
● upper bound < 0.
● gap <= 0
You should test your program for different kind of scenarios, here
are some examples for testing:
○ Upper bound = 5, gap = 1: results 0, 1, 2, 3, 4, 5. sum=15, and 5,
4, 3, 2, 1, 0. sum=15.
○ Upper bound = 5, gap = 2: results 0, 2, 4. sum=6 and 5, 3, 1.
sum=9.
○ Upper bound = 5, gap = 7: results 0. sum=0 and 5. sum=5.
○ Upper bound = 15, gap = 7: results 0, 7, 14. sum=21 and 15, 8,
1. sum=24.
○ Upper bound = 0, gap = 1: results 0. sum=0 and 0. sum=0.
There is a space after every colon.
Example console
output
Enter upper bound: 20
Enter gap: 3
Go forward: 0, 3, 6, 9, 12, 15, 18.
Sum of numbers = 63
Go backward: 20, 17, 14, 11, 8, 5, 2.
Sum of numbers = 77
Question 3. Write a function that satisfies the following specifications.
Function question_3
Parameters –
Return Value –
Detail Information This function computes the total interest earned for a given year based on
the following rated.
Base Interest:
Ordinary Account (OA): 2.5% per annum.
Special Account (SA): 4% per annum.
Medisave Account(MA): 4% per annum.
Retirement Account(RA): 4% per annum (only applicable for those age 55
and above.)
Extra Interest:
Age Extra interest (capped at \$20,000 for
OA)*
Below 55 years old 1% per annum on the first \$60,000
55 years old and above 2% per annum on the first \$30,000, 1% per
annum on the next \$30,000
* OA contributes a maximum of \$20000 to the extra interest calculation.
Using the prompts shown in the example, calculate and display the interest
earned for in one year assuming no money was deposited into the account
during that period.
You do not have to round the interest up or down.
You should test your program for different kind of scenarios, here is
another example for testing:
35, 30000, 10000, 20000 -> \$2450.00
Example 1 console
output
Enter current age: 35
Enter current amount in OA: 10000
Enter current amount in SA: 10000
Enter current amount in MA: 10000
Your interest rate this year will be \$1350.00
Example 2 console
output
Enter current age: 65
Enter current amount in OA: 10000
Enter current amount in SA: 10000
Enter current amount in MA: 10000
Enter current amount in RA: 10000
Your interest rate this year will be \$2150.00
Question4. Write a function that satisfies the following specifications.
Function Name question_5
Detailed
“patient_zero[20150203].txt”, “[shn]shn_batch101.csv”,
“[x264]psa_recording[1280×720].mp4”
and would like to automatically clean up these filenames by removing
all instances of square brackets and the contents contained within.
1. Prompts for filenames with “Filename?” repeatedly, until an empty
string is given
2. Prints a string with all the cleaned filenames, separated by
commas, without any spaces between.
Example Console
output
Filename?patient_zero[20150203].txt
Filename?[shn]shn_batch101.csv
Filename?[x264]psa_recording[1280×720].mp4
Filename?
patient_zero.txt,shn_batch101.csv,psa_recording.mp4
