### Exercise 1

Exercise 1. Create a two-variable addition calculator cal_sum(a, b) that returns the sum of the two variables.

Exercise 1: 创建一个双变量加法计算器 cal_sum(a, b)，它会返回这两个变量的和。

def cal_sum(a, b):
# YOUR CODE HERE


# In order to make sure your program works, testcases are written and executed.
# Here is an example testcase that you might write for testing.

# In python assert keyword helps in debugging.
# This statement simply takes input a boolean condition, which doesn’t return anything when it's true,
# but if it is computed to be false, then it raises an AssertionError along with the optional message provided.

assert cal_sum(1, 2) == 3


### Exercise 2

EN

Exercise 2. In a function FullName(name, capital=True),

• a. Create a string variable str1 that stores the string "Full Name: "

• b. if capital == True, use upper() function to convert name into Uppercase letters and assign this to a variable NewName

• c. if capital == False, use title() function to convert the first character of each word in name to Uppercase letter and the other characters in lower case and assign this to a variable NewName

• return the string "Full Name: " + NewName

Example

FullName("guido vAn rossum", capital = True)
Expected output: 'Full Name: GUIDO VAN ROSSUM'

FullName("guido vAn rossum", capital = False),
Expected output: 'Full Name: Guido Van Rossum'

def FullName(name, capital=True):
str1 = "Full Name: "
# YOUR CODE HERE


### Exercise 3

EN

Exercise 3. In a function first_word(arg1), use split() function to separate the argument arg1 by "," and return the first word.

Example

first_word('Hello, world!')

Expected output:

'Hello'

def first_word(arg1):
# YOUR CODE HERE


### Exercise 4

EN

Exercise 4. In a function clean_string(arg1),

• use strip() function to remove trailing and ending white spaces from "arg1", and
• capitalize the first character.
• return the output.

Example

clean_string("   having fun in Python   ")

Expected output:

"Having fun in Python"

def clean_string(arg1):
# YOUR CODE HERE


### Exercise 5

EN

Exercise 5. In a function first_last(arg1), return the a+b, where a is the first character and b is the last character of arg1.

Example

clean_string("My Name is Andrew")

Expected output:
"Mw"


Hint

• The function len() gives you the length of the list. For example, len('abcd') returns 4. So, the last element of arg1 is therefore indexed at len(arg1) - 1.
def first_last(arg1):
# YOUR CODE HERE


### Exercise 6

EN

Exercise 6. In a function volume_c(radius, height),

• Create a variable vol to calculate the volume of cone, assuming pi is equal to 3.14. Given the formula for volume of cone is: $volume = \frac{1}{3}, \pi r^{2}h$, where r is the radius and h is the height.

• return vol

def volume_c(radius, height):
# YOUR CODE HERE

Example

divisible_by_2(10) -> True
divisible_by_2(15) -> False


Hint

def letter_grade(grade):
# YOUR CODE HERE


### Question 4

EN

Question 4. Define a function cumsum(num). The function returns the sum of all positive integers smaller or equal to num.

Example

cumsum(4) -> 1 + 2 + 3 + 4 = 10
cumsum(5.5) -> 1 + 2 + 3 + 4 + 5 = 15


Hint

• int() converts a float type value into an interger.
def cumsum(num):
# YOUR CODE HERE


### Question 5

EN

Question 5. Define a function even_sum(num), where num is a positive number. The function iterates all the integers numbers from 0 to num, sums them up if they are even numbers, and returns the sum.

Example

even_sum(4) -> 2 + 4 = 6
even_sum(8.5) -> 2 + 4 + 6 + 8 = 20

def even_sum(num):
# YOUR CODE HERE


### Question 6

EN

Question 6. Define a function num_char_before_period(sentence). The function returns the number of characters in a given string before encountering the symbol ".", using while loop. Assume the argument sentence always include a period "."
Example

num_char_before_period('I love python.') -> 13
num_char_before_period('I hate you. I love python.') -> 10
num_char_before_period('...') -> 0


Hint

• != denotes not equal.
• the element on index i can be accessed by using sentence[i].
• len(sentence) gives the number of characters in a the sentence
def num_char_before_period(sentence):
# YOUR CODE HERE


### Question 7

EN

Question 7. Define a function remove_vowel(string1). The function returns a new string with all vowels removed. Vowels are any of a, e, i, o, u and A, E, I, O, U.

Example

remove_vowel('python') -> 'pythn'
remove_vowel('I love ice cream') -> ' lv c crm'


Hint

• you can check if a character or an element (not) in a string or a list by using in, or not in.
def remove_vowel(string1):
vowels = ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]
output = ""
# YOUR CODE HERE


## Chapter 4 - Quiz 4

This is the in-class quiz for Chapter 4 (Data Structures Part 1) for students of session 1004. Your solution can account for maximum 2.5% of your final grade.

Note

• Write your code after you see # YOUR CODE HERE
• Read the instruction of each question. You have a limited time to submit: Tue 21 Mar, h.17:00. Only your last submission counts.
• Copying the solution of other students is forbidden.
• This quiz will be auto-graded. The auto-grading will check that your answers to the question is correct (or close to be correct). If your submission fails the auto-grade, you will get 0.

### Question1

EN

Question1. Define a function first_last(listA) that returns a list with the first and last element of listA interchanged.

Example

first_last([1, 2, 3]) -> [3, 2, 1]
first_last(["a", "b", "c", "d"]) -> ["d", "b", "c", "a"]


Hint

• To create a list with the same dimension of list1
n = len(listA)
list0 = [0]*n

def first_last(listA):
n = len(listA)
list0 = [0]*n
# YOUR CODE HERE


### Question2

EN

Question2. Define a function odd_numbers(). The function iterates all the numbers from 0 to 20 using a for loop and returns all the odd numbers in a list.

Hint

• list.append() is a built-in method in Python to store items into a list.
def odd_numbers():
res = []
# YOUR CODE HERE


### Question3

EN

Question3. Define a function group_student(set1, set2, left = True). The function returns a set:

1. Students who are in set1 but not in set2, if left=True
2. Students who are in both set1 and set2 at the same time, if left=False


Hint

• Use set1 = {...} to create a set.
• a - b returns items in a but not in b
• a & b returns items in both a and b

Example

python = {"Alice", "Bob", "Fiona", "Luke", "Tom"}
econ = {"Alice", "Blaire", "Courtney", "David", "Luke"}
group_student(python, econ) -> {'Bob', 'Fiona', 'Tom'}

def group_student(set1={"Alice","Bob","Fiona","Luke","Tom"}, set2={"Alice","Blaire","Courtney","David","Luke"}, left = True):
# YOUR CODE HERE


### Question4

EN

Write a function called tuple_stats that takes in a tuple of integers as input and returns a tuple containing the following statistics:

1. The minimum value in the tuple.
2. The maximum value in the tuple.
3. The sum of all the values in the tuple.
4. The mean of all the values in the tuple.

Example

tup1 = (3, 5, 1, 8, 2)
tuple_stats(tup1) -> (1, 8, 19, 3.8)


Hint

• To find the minimum and maximum values in a tuple, you can use the built-in min and max functions in Python. For example, min((3, 5, 1, 8, 2)) will return 1.

• To find the sum of all the values in a tuple, you can use a loop to iterate through each element in the tuple and add it to a running total. You can start the total at 0 and update it with each iteration of the loop.

• To find the mean of all the values in a tuple, you can divide the sum of all the values by the length of the tuple. You can use the len function to find the length of the tuple.

def tuple_stats(tup):
# YOUR CODE HERE


### Question5

EN

Question5. Write a function called count_vowel that takes in a string and return the number of unique vowels forming the string. This function is case sensitive, such that the maximum number of vowel is 10.

Example

count_vowel("Hello World") -> 2
count_vowel("AAA nsn") -> 1
count_vowel("ll cnsnt") -> 0
count_vowel("aAeE") -> 4


Hint

vowel = ["a","e","i","o","u", "A","E","I","O","U"]
set() # convert a list to set, where element are unique

def count_vowel(str_arg):
# YOUR CODE HERE
