Python Assignment – Intro to Functions and Lists

 

Here’s what I accomplished:

• Wrote a function that prints a 3-line greeting using someone’s name on each line.

• Stored three names in a list and used a loop to greet them all.

• Created a function that prints a nicely formatted full name from first and last name.

• Built an addition calculator that prints results, then rewrote it to return the result instead.

• Learned that pow(16, 1/2) works to get the square root of 16 (returns 4.0).

• Played with list and tuple syntax:

  • Found out that 3 * x repeats a list.

  • You can do x + y (joins the lists) but can’t do x - y.

  • Lists are mutable, but tuples can’t be changed.

I didn’t run into any issues using the online Python compiler, and I’m already seeing how functions and data structures come together in Python. Looking forward to the next challenge.


The Output:

Hello, Alice Smith! Hope you're having a great day.

Alice Smith, just wanted to say you're awesome!

Take care, Alice Smith!

---

Hello, Bob Johnson! Hope you're having a great day.

Bob Johnson, just wanted to say you're awesome!

Take care, Bob Johnson!

---

Hello, Carla Gomez! Hope you're having a great day.

Carla Gomez, just wanted to say you're awesome!

Take care, Carla Gomez!

---

Hello, Alice Smith!

Hello, Bob Johnson!

Hello, Carla Gomez!

5 + 3 = 8

10 + 4 = 14

2 + 9 = 11

Result 1: 8

Result 2: 14

Result 3: 11

Using pow(16, (1/2)): 4.0

Better version: pow(16, 0.5): 4.0

3*x = [1, 2, 3, 4, 5, 1, 2, 3, 4, 5, 1, 2, 3, 4, 5]

x+y = [1, 2, 3, 4, 5, 11, 12, 13, 14, 15]

x[1] = 2

x[0] = 1

x[-1] = 5

x[:] = [1, 2, 3, 4, 5]

x[2:4] = [3, 4]

x[1:4:2] = [2, 4]

x[:2] = [1, 2]

x[::2] = [1, 3, 5]

After x[3]=8, x = [1, 2, 3, 8, 5]

=== Code Execution Successful ===

My Code:

# Part 1: Greeting Function

def greet(name):

    print(f"Hello, {name}! Hope you're having a great day.")

    print(f"{name}, just wanted to say you're awesome!")

    print(f"Take care, {name}!")

# Greet three people using a loop

people = ["Alice Smith", "Bob Johnson", "Carla Gomez"]

for person in people:

    greet(person)

    print("---")

# Full Name Function

def full_name(first, last):

    print(f"Hello, {first} {last}!")

full_name("Alice", "Smith")

full_name("Bob", "Johnson")

full_name("Carla", "Gomez")

# Addition Calculator

def add_numbers(a, b):

    print(f"{a} + {b} = {a + b}")

add_numbers(5, 3)

add_numbers(10, 4)

add_numbers(2, 9)

# Return Calculator

def add_and_return(a, b):

    return a + b

result1 = add_and_return(5, 3)

print(f"Result 1: {result1}")

result2 = add_and_return(10, 4)

print(f"Result 2: {result2}")

result3 = add_and_return(2, 9)

print(f"Result 3: {result3}")

# Part 2: pow(16, (1/2))

print("Using pow(16, (1/2)):", pow(16, (1/2)))

print("Better version: pow(16, 0.5):", pow(16, 0.5))

# Part 3: List and Tuple operations

x = [1, 2, 3, 4, 5]

y = [11, 12, 13, 14, 15]

z = (21, 22, 23, 24, 25)

print("3*x =", 3*x)

print("x+y =", x + y)

# print("x-y =", x - y)  # not supported

print("x[1] =", x[1])

print("x[0] =", x[0])

print("x[-1] =", x[-1])

print("x[:] =", x[:])

print("x[2:4] =", x[2:4])

print("x[1:4:2] =", x[1:4:2])

print("x[:2] =", x[:2])

print("x[::2] =", x[::2])

x[3] = 8

print("After x[3]=8, x =", x)

# z[3] = 8  # This would give an error: tuples can't be modified
