Work with a list:

1. Create a list `fruits = ["apple", "banana", "cherry"]`.
2. Print the second item.
3. Change "apple" to "kiwi".
4. Add "orange" to the end of the list (`append`).

fruits = ["apple", "banana", "cherry"]
print(fruits[1])      # banana
fruits[0] = "kiwi"
fruits.append("orange")
print(fruits)

Extract part of a list:

1. You have `fruits = ["apple", "banana", "cherry", "orange", "kiwi", "melon", "mango"]`.
2. Print items from the third to the fifth (index starts at 0).

fruits = ["apple", "banana", "cherry", "orange", "kiwi", "melon", "mango"]
print(fruits[2:5]) # ['cherry', 'orange', 'kiwi']

Work with tuples (immutable):

1. Create a tuple `fruits = ("apple", "banana", "cherry")`.
2. Print the first item.
3. Try to change the first item and explain the result in a comment.

fruits = ("apple", "banana", "cherry")
print(fruits[0])

# fruits[0] = "kiwi"
# This will raise a TypeError because tuples are immutable.

Work with sets (unordered, no duplicates):

1. Create a set `fruits = {"apple", "banana", "cherry"}`.
2. Add "orange" to the set (`add`).
3. Add "apple" again and print the set to see no duplicates.

fruits = {"apple", "banana", "cherry"}
fruits.add("orange")
fruits.add("apple") # will not be added because it already exists
print(fruits)

Store key-value data:

1. Create a dictionary `car = {"brand": "Ford", "model": "Mustang", "year": 1964}`.
2. Print the value of "model".
3. Change "year" to 2020.
4. Add a "color" key with value "red".

car = {
  "brand": "Ford",
  "model": "Mustang",
  "year": 1964
}
print(car.get("model"))
car["year"] = 2020
car["color"] = "red"
print(car)

Print dictionary contents:

1. Use a `for` loop to print all keys and values in the `car` dictionary.
2. Use `car.items()`.

for key, value in car.items():
    print(key, value)

Create a complex structure:

1. Create a dictionary `myfamily`.
2. It contains two keys: "child1" and "child2".
3. Each child is a dictionary with "name" and "year".
4. Print the name of the second child.

myfamily = {
  "child1" : {
    "name" : "Emil",
    "year" : 2004
  },
  "child2" : {
    "name" : "Tobias",
    "year" : 2007
  }
}
print(myfamily["child2"]["name"])

Remove data from a list:

1. You have `fruits = ["apple", "banana", "cherry"]`.
2. Remove "banana" using `remove`.
3. Remove the last item using `pop`.

fruits = ["apple", "banana", "cherry"]
fruits.remove("banana")
fruits.pop()
print(fruits)

Create a list in a compact way:

1. You have `fruits = ["apple", "banana", "cherry", "kiwi", "mango"]`.
2. Create a new list `newlist` that includes only fruits containing "a".
3. Use a list comprehension (one line).

fruits = ["apple", "banana", "cherry", "kiwi", "mango"]
newlist = [x for x in fruits if "a" in x]
print(newlist)

Copy a list correctly:

1. You have `thislist = ["apple", "banana"]`.
2. Create a copy `mylist` using `copy()`.
3. Make sure changes to the copy do not affect the original.

thislist = ["apple", "banana"]
mylist = thislist.copy()
print(mylist)
