Free Coding Bootcamp - Go from Zero to Software Engineer

This Bootcamp will follow the roadmap covered in this video

In this lesson, we go over lists and how we can use it to store more than 1 item(s).

Thank you so much, I had been always afraid of this topic at school because never understood it and then boom, you upload almost 7 mins video and suddenly all clear!

hey man, just started coding about 2 hours ago. I got some friends that code in college and they gave me 2 problems to work on that are fairly easy. they wanted me to input 3 numbers and have my code identify the largest one, as well as be able to tell if that number was even or odd. Thanks to your vids and specifically the conditional functions one. I was able to (with a little trial and error lol) code that program they asked!! so thanks man, your vids are super helpful!!

[oliurrahman]

nice and easy, tried doing a worked example with like a grocery list and it worked perfectly. imma try integrate the input somehow lol see how it goes..

We can also use numbers[-1] to get the last value

[Edwinteachescode]

mind you if you are using a string in your list always quote each item " "... wonderful video

can you put chime song in the background

I literally typed the code exactly as it's listed on the video but when I click run....nothing!

Hi, coming back to this from a later video. You mention that lists have to consist of the same type. I'm wondering why I was able to use both another class and other variables and this program still works? Am I misunderstanding?

class Dog():
def __init__(self, name):
self.name = name

class Person():
def __init__(self, name):
self.name = name

humans = [Person("Vincent"), Person("Bob"), Person("Joe"), Person("Vincent"), Dog("Kyuubi"), Dog(Dog(3)), Person(4)]

index = 0

while index < len(humans):
human = humans[index]
if human.name == "Vincent":
humans.pop(index)
else:
index += 1

for human in humans:
print(human.name)


Output:

Bob
Joe
Kyuubi
<__main__.Dog object at 0x7f88a67c44f0>
4

I don’t understand why u minus 1 though?

[stephanieo]

You can also just use -1 without the len or the 5

How should I effectively study each section of this course? I plan on staying rewatching the Python videos for a month to better internalize it. Then moving on to the next section and repeating. Is that a good plan or is there a better one?
