Python - All Possible Permutations w/ Recursion

I explain how to create a function to return all possible permutations of any given string.

Struggling many years to understand this, finally gotcha your video and u made my day bro

[alasdairmacintyre]

Dude thank you for that simple explanation "2nd function call, first recursive call." I have been trying to wrap my mind around how code like this works but you really simplified it

[Mullemeck]

Thank a lot, especially for visualizing the execution of the code. It made me fully understand the solution. I have struggled with permutations and have seen a couple of other explanations/solutions, but yours is the only one that walked through the execution in detail and thus made me really understand the code.

Dude, I seriously cannot thank you enough for this video. I was struggling with the idea of recursion and you filled in the gaps in my knowledge. Thanks a million

[yiqiongxiao]

i struggled so much to understand permutation and this video is so far the best. detailed explanation! awesome and thank you so much

[harshsaxena]

this solution deserves a like ..best explanation

[MuratJumashev]

This video deserves more views! You nailed it!!!

[Strawlocka]

you're a life saver. Thank you for making this video

[vivekshinde]

banged head hundred times to understand this..thank u for making it so simple

[opinions]

Your solution rocks my friend
... returns love from India...

[kevinyuan]

best video explanation of recursion, bro deserves a W👍

[hoanghuynh]

Love it, due to u with visual explanation, i comprehend now

[victor.novorski]

Saw you in that Rabbit getting scared by its own

Now your subscriber

Your explanation was the best! Thank you so much. I haave been stuck on this for so long.

[fardeendingankar]

Trust me man you just nailed this i was trying for long to get being from non-Cs background it was difficult to digest but hats off to you

[mrKnown]

This is best available code and explaination i guess

[tigranhayrapetyan]

Tnank you! It was very helpful explanation how it works

[CrushOfSiel]

Damn, I was so close to the answer. I just couldn't write the whole thing in any correct order. I had the base case, I knew I needed a loop somewhere with perm[:i] + char + perm[i:] and I knew I needed the function to call itself but I just could'nt put it all together >< so frustrating. Your solution makes perfect sense but I don't know if I could ever get that to all come out of my head the correct way. It seems so complicated, building a list, doing the permutations, going through the list to add more complex permutations...

[amitupadhyay]

Perfect explaination, you sit, take a bow

[TutonicKnight]

Thanks for the video. I've been racking my brain on this for a few days because i was under the impression that the return needed to be the function call...

My brain kept coming back to having the recursive call go into a variable, but thought it wasn't allowed in a recursive function. Turns out i failed because i was too strict about what i thought the "rules" were... lol

Here's an updoot and a sub :P
