It will insert each letter like a one item of a list, because string is also a list. You can also insert a list into another list.
So, if you make the string you want to insert an item of a list ['BlueBerry'] it will insert the whole word as one item:
fruits[2:2] = ['BlueBerry']

When you want to insert a number like this, it also must be an item of a list. Otherwise it will make an error.
fruits[3:3] = [5]

It can be inserted more items at once:
myList = ['a', 'b', 'c']
myList[1:1] = ['one', 2]
-> myList will be ['a', 'one', 2, 'b', 'c']

great video but you have been spelling strawberries wrong but seriously thanks for the help

[barnabasbor]

Thank you very much Tim, for making these kind of videos for beginners. I would also mention the insert method here, but overall it was really great.

"Let's spell that correctly: "blueberrys"" xD
I died at that moment

In your text-based tutorial, it should be myList[1:1] = [-40] in insertion using slice part

[DeadManRising]

fruits[2:2] = 'BlueBerry';
print(fruits);
why does it make a list part of each letter?

[AyushKumar-gpys]

while adding a fruit name in the list say papaya instead of b, output included each letter separately, can you suggest the modification. Output example ['apples', 'p', 'a', 'p', 'a', 'y', 'a', 'bananas]
Code:
fruits = ['apples', 'bananas']
fruits[1:1] = 'papaya'
print(fruits)

Nice video
Watched at 2x
Meet you in next one

Instead of 'b', i used 'tomatoes'

fruits[0:0] = 'tomatoes'

['t', 'o', 'm', 'a', 't', 'o', 'e', 's', 'apples', 'pears', 'strawberries', 'blueberries']

what'd I break?

[mephystto]

r u kidding me? u don't need for loops to print out lists?

[wongkingshun]

i typed banana instead of b, and it turns out 'b', 'a', 'n', 'a' and so on

[mikeb]

Why use slice operators for a list rather than .insert(), beyond being shorter?

[daniel_dominguezs]

Great video! I've been testing a few things while watching it and i found out that if you write:
fruits[1:2] = "b" It replaces the item in te second position
fruits[1:3] = "b" it replaces the item in the second position and deletes the item in third position

do you guys know why that happens?

Strawberries and blueberries 😉 Also Python works differently now and this video will no longer produce the results specified.

[AmirShooshtarian]

great video but i have a question
why when i add a sentence using this method to the beginning of my list it all comes out every letter seperated ?

[wongkingshun]

I have watch the 6 hours long version, so it feels like a revisoin to me.
I think i know the content, but forgot this is call slice operator.

The devil took the first slice of his birthday cake. There was something written on it. HELL. He smiled and ate it... (in case if you have zero sense of humor or your just dumb the first time he sliced, the output was HELL)
