Here’s are some of the most commonly used list methods in Python:

1. append(item): Adds an item to the end of the list.
2. extend(iterable): Adds all the elements of an iterable (like list, tuple, string etc.) to the end of the list.
3. insert(index, item): Inserts an item at a specific position in the list.
4. remove(item): Removes the first occurrence of the item from the list.
5. pop(index): Removes and returns the item at the given index. If no index is specified, it removes and returns the last item in the list.
6. index(item): Returns the index of the first occurrence of the item in the list.
7. count(item): Returns the number of times the item appears in the list.
8. sort(): Sorts the items in the list in ascending order.
9. reverse(): Reverses the order of the items in the list.
10. clear(): Removes all items from the list.

Here’s an example of how you might use some of these methods:

# Create a list
numbers = [1, 2, 3, 4, 5]

# Append a number to the list
numbers.append(6)

# Extend the list with another list
numbers.extend([7, 8, 9])

# Insert a number at a specific position
numbers.insert(0, 0)

# Remove the first occurrence of a number
numbers.remove(0)

# Pop the last number from the list
last_number = numbers.pop()

# Get the index of a number
index_of_five = numbers.index(5)

# Count the occurrences of a number
count_of_five = numbers.count(5)

# Sort the numbers
numbers.sort()

# Reverse the numbers
numbers.reverse()

# Clear the list
numbers.clear()

1. On a Mac, go to VS Code
2. Navigate to Preferences -> Settings
3. Search Settings for ‘editor.tokenColorCustomizations’
4. In-between two curly braces, type “comments”: #FF0000″

 "editor.tokenColorCustomizations": {
        "comments": "#FF0000"
    }

I didn’t look for an extension, but I’m sure one exist. Since I’m starting out I want to build all the right muscles early on to get an idea of how things work.

So this challenge was a bit tricky because the example given was set up differently. At first it looked like I needed to change the function into a var or create an object with key:value given the names in the code tests module. It wasn’t until I watched the video that the explanation made sense.

Set up:

Modify the function checkObj to test if an object passed to the function (obj) contains a specific property (checkProp). If the property is found, return that property’s value. If not, return "Not Found".

function checkObj(obj, checkProp) {
  // Only change code below this line
  if(obj.hasOwnProperty(checkProp)) {
    return obj[checkProp];
  } else {
    return "Not Found";
  }
  // Only change code above this line
}
