Create a simple function:

1. Define a function named `my_function`.
2. The function prints "Hello from a function".
3. Call the function to run it.

def my_function():
  print("Hello from a function")

my_function()

Pass data to a function:

1. Define a function `my_function` that takes an argument `fname`.
2. The function prints the name followed by "Refsnes".
3. Call it with the name "Emil".

def my_function(fname):
  print(fname + " Refsnes")

my_function("Emil")

Handle a variable number of inputs:

1. Define a function that accepts `*kids`.
2. Print "The youngest child is " followed by the third item (index 2).
3. Call it with "Emil", "Tobias", "Linus".

def my_function(*kids):
  print("The youngest child is " + kids[2])

my_function("Emil", "Tobias", "Linus")

Handle a dictionary of arguments:

1. Define a function that accepts `**kid`.
2. Print the last name `kid["lname"]`.
3. Call it with `fname="Tobias", lname="Refsnes"`.

def my_function(**kid):
  print("His last name is " + kid["lname"])

my_function(fname = "Tobias", lname = "Refsnes")

Return a result from a function:

1. Define `my_function(x)` that returns `5 * x`.
2. Print the result for input 3.

def my_function(x):
  return 5 * x

print(my_function(3))

Create an anonymous function:

1. Create a `lambda` function that takes `a` and adds 10.
2. Store it in a variable `x`.
3. Print the result of `x(5)`.

x = lambda a : a + 10
print(x(5))

Use an external module:

1. Import a module `mymodule` (assume it exists).
2. Use it with the alias `mx`.
3. Print `mx.person1["age"]`.

import mymodule as mx

# print(mx.person1["age"])

Work with dates:

1. Import the `datetime` module.
2. Print the current time using `datetime.datetime.now()`.
3. Print only the current year.

import datetime

x = datetime.datetime.now()
print(x)
print(x.year)

Use math functions:

1. Use `min` and `max` to find the smallest and largest numbers in `(5, 10, 25)`.
2. Use `abs(-7.25)` to get the absolute value.
3. Use `pow(4, 3)` to calculate a power.

x = min(5, 10, 25)
y = max(5, 10, 25)
z = abs(-7.25)
p = pow(4, 3)

print(x, y, z, p)

Convert data:

1. Import `json`.
2. You have a dictionary `x = {"name": "John", "age": 30}`.
3. Convert it to JSON text with `json.dumps(x)`.
4. Print the result.

import json

x = {
  "name": "John",
  "age": 30,
  "city": "New York"
}

y = json.dumps(x)

print(y)
