Finally, someone who actually explained this quite elegantly and simply.

@ashfaqtunio1311 7 лет назад

This is great. I always found these functions confusing, but you have explained them so clearly, I am going to use them extensively in my coding. Thanks a lot.

At last, an excellent and concise explanation of this functions, loved this clip ! Thanks

@jorgeespinoza3938 4 года назад

I"ve seen many videos about this topic, but this is, BY FAR, the BEST. Not only the pace was the adecuate fir beginners like me, but it was also full of examples and alternatives. Thanks for publishing this video. Thumbs up thumbs ☝!!

@prasadfalke376 4 года назад

Joe, you just helped me understand Lambda and other functions. This will be the easiest explanation I have seen so far. (a week into Python programming)

@sushantregmi2126 5 лет назад

Thanks for clarifying these so eloquently. Loved it.

@upendrauppi5778 7 лет назад

lot of confusion regarding comprehensions,lambda,map functions~!today i got clarity !!thk u so much!!!

@afterhours39 4 года назад

Subbed. Don't know why RU-vid hasn't brought me to your channel before. Your explanation helped me understand three functions (two of which I hadn't even heard of) that I didn't understand before. Thank you.

@alifiras5651 6 лет назад

i watched alot of videos about that functions, i couldn't understand any one of them! except yours, it was awsome!

@newsbie-thekidsnewsstop1811 5 лет назад

One of the most effective lessons I have seen!

@MultiDickers 7 лет назад

The best Tutorial i have seen so far. well explained and i like the way u relate the subject with other similar operations.

@suacasa293 4 года назад

Thanks a lot from Brazil! I always found them very confusing, now I am happy with this learning experience!

@mulengamulenga5449 Год назад

Wow ... that's so simplified!!! I finally got someone who me me see all of them at once in a simplified manner along with how they can be used together. Thanx Joe!!!

@rmalshe 8 лет назад

This extremely simple lesson can save one hundreds of lines of coding. Thanks for creating it!

@TasX Год назад

Is this actually useful? I feel like you could do the same, even faster and more optimized with a simple numpy package

@alexyuwen 3 года назад

Small mistake at 5:20, the map function would only work if square was defined as def square(num): return num**2 since the parameter would need to be a number, not a list.

@onemanenclave 2 года назад

That approach was meant to be equivalent to the _whole_ thing on the right, not just to the lambda function ;)

so easy to follow, great job! for the last part: i think the code needs to be updated and import functools import functools print(functools.reduce(lambda x,y:x*y,n))
