1. Create a Person class with an initializer that defines a first name, last name, gender, and occupation variables. Include an introduce() function that prints out an introduction for the person using any of the information included as member variables.

2. Now, create a person that is yourself and use the introduce function to introduce yourself

3. Create a Job parent class with salary, location, and company name variables and a work() function that prints out “I’m doing work”. Then, create two child classes called Engineer and Accountant that each have their own unique functions. These functions can do anything you’d like.

4. Create a NumPy array [10, 20, 30, 40] from a normal Python list

5. Turn a NumPy array [1, 2, 3] into [12, 24, 36]

6. Create a 4 by 5 NumPy array of ones and then reshape it into a 10 by 2 array

7. Mask a ten-element array to only include 3, 6, and 9

1. Create a Person class with an initializer that defines a first name, last name, gender, and occupation variables. Include an introduce() function that prints out an introduction for the person using any of the information included as member variables.

   1. class Person:

def __init__(self, firstName, lastName, gender, occupation):

    self.firstName = firstName

    self.lastName = lastName

    self.gender = gender

    self.occupation = occupation

def introduce():

print(“Hello, I am “ + self.firstName +  “ “ + self.lastName + ”and I 

am a ” + self.occupation)

2. Now, create a person that is yourself and use the introduce function to introduce yourself

   1. anna = Person(“Anna”, “Guo”, “Female”, “Student”)

anna.introduce()

3. Create a Job parent class with salary, location, and company name variables and a work() function that prints out “I’m doing work”. Then, create two child classes called Engineer and Accountant that each have their own unique functions. These functions can do anything you’d like.

   1. class Job():

def __init__(self, salary, location, companyName):

self.salary = salary

self.location = location

self.companyName = companyName

def work(self):

print(“I am doing work.”)

class Engineer(Job):

def build(self):

print(“I am building stuff.”)

class Accountant(Job):

4. Create a NumPy array [10, 20, 30, 40] from a normal Python list

   1. L = [10, 20, 30, 40]

np_L = np.array(L)

5. Turn a NumPy array [1, 2, 3] into [12, 24, 36]

   1. l1 = np.array([1, 2, 3])

l1 = 12*l1

6. Create a 4 by 5 NumPy array of ones and then reshape it into a 10 by 2 array

   1. l2 = np.ones((4, 5))

l2.reshape(10, 2)

7. Mask a ten-element array to only include 3, 6, and 9
