Day 5 of 6 months Data science roadmap 2023 has been completed today. Great teaching skills and Exercises.

[TeemoCity]

Thank you so much for all these videos. I think these are the most clear and concise programming videos on YouTube.

[vignesan]

brother I'm data science intern student your videos are very very very useful for me.i have give you 5 star rating on this videos ⭐⭐⭐⭐⭐. thank you brother❤🌹🙏.

How do I print the last three items in reverse print(items[-1:-4])?

[sarimmasood]

To remove any item from the list:
>>>items=['butter', 'bread', 'egg']
>>>del items[1] | del items[index]

>>>items
['butter', 'egg']

[riccardoholder]

for those who are starting, the TypeError: object does not support item assignment**** is will happen when you put items=("milk", "pasta", "fruits", "bread") but the solution is the square bracket[ ] so the answer us items=["milk", "pasta", "fruits", "bread"], I hope this help because I am now starting my journey in data science lol'

This playlist is very helpful, thank you so much!!

Sir, Is the level of the given practice questions are enough for data science ?

[vinayrb]

items[0]='chips'
Traceback (most recent call last):
File "<pyshell#57>", line 1, in <module>
items[0]='chips'
TypeError: 'tuple' object does not support item assignment

Not taking replace item.

[shafayet]

What if I want to access to two elements that are not positioned adjacently in the list, say 'bread' and 'fruits'?

[vinayrb]

items
('biscits', 'oil', 'groceries')
>>> items.insert(1, 'fruits')
Traceback (most recent call last):
File "<pyshell#66>", line 1, in <module>
items.insert(1, 'fruits')
AttributeError: 'tuple' object has no attribute 'insert'

[dinuherath]

When I use this items.insert(1, "Butter") I get butter 2 times, Why ?
['bread', 'Butter', 'Butter', 'Pasta', 'fruits', 'veggies']

[harshbhojak]

What if we want to remove -1 (The last thing from our list)
is it
items.remove(-1)?
I'm just able to replace it with other thing:(

[sravanthitoomkunta]

we have small list so we can be able to predict the index then what if we have a long list?

[MaiaUnfiltered]

This is excellent stuff. Thank you so much Sir!

[MrRawkz]

So I got curious!!. When you combine the items food and bathroom it works fine. But lets say if I use the insert function to add an item to the food list it does not get updated in the items list. Is there a separate command to update the list?

[vinayrb]

items.append ("butter")
Traceback (most recent call last):
File "<pyshell#61>", line 1, in <module>
items.append ("butter")
AttributeError: 'tuple' object has no attribute 'append'

Error in adding Butter to list.

[katienefoasoro]

what if i want to find the index positon of one element of items? for example i don't know the index position of 'fruits' and i want the code to display it
thanks for videos

[jennenaresh]

good sir I am non technical but I am understanding thank you for your videos
