as a software engineer who uses python, i have some feedback. first, i think the video is great. these are the same differences i would highlight - though i'd very likely also include f-strings. so i want to make it clear up front that i like the video.

with that out of the way, the problem i see is there are two types of people - those who write code and those who run it. your audience is likely the latter. given this is true, people honestly just need to know "if it doesn't work in python 3, try python 2" or vice-versa. you've proven yourself in this video that a) python 3 is better, and b) python 2 is dead, and c) converting code between the two is quite simple. this makes me wonder why you're even covering it at all? if you need to convince yourself to convert everything to python 3 do it. it's not difficult (as you yourself have shown) so just get on with it already.

in a few years time you will look back at this and wonder why you kept bring up python 2. just assume everything is python 3, make everything python 3, and get on with your life. it reminds me of my dad trying to justify the need to use his windows xp system. i get it, he has emotional attachment, but discussing it to newbies at python serves no purpose other than to confuse them - particularly given your channel is not a programming channel.

Basically you just check if you have () in print

Commands used in this video for Python 2:
1. python/python2, both of these commands will launch Python/Python 2 in the terminal.
2. print("null byte")/print "null byte", both of these commands will make Python 2 print out whatever is inbetween the two quotation marks.
3. type(2), an integer in computer science is a digit with no decimal places.
4. type(2.5), a float is capable of storing decimal places.
5. type(2.0), this command will return as a float.
6. print(3/2), when we divide two integers in Python 2 it's going to return as a integer.
7. print(3.0/2.0), this command will also return as a float.
8. print(u"now, this is unicode"), if we want to print this as Unicode then we're going to have to specify that.
9. print("this is actually ASCII"), when we print this by default it will not use Unicode but ASCII instead.

Probably just scratched the surface with this video, you should make this into a small series

@Null Byte
Hello
do you know a way to automatically convert python 2 code to python 3

[dekuwar]

Well python 2 doesn't support anymore in kali new versions

what happened to the previous host, cody was it?

Nice video. Great difference explanation.

I think python actually started in 60s and 70s and wasnt highly used till 90s

Install Tilix. You will never use another terminal again
