Python Lambda List Range Question

Question

i = list (range(1,4))
s = list (map(lambda x:x**2,i))
print(sum(s))
Solution: 14

Map lambda is asking me to repeat a function?

Answer 1

2**2 == 4
3**2 == 9

Answer 2

list(range(1,4)) is a range from 1 to 3 inclusive, which means:
"i = [1,2,3]";

"x**2" is "x" squared;

print(sum(s)) =>
print(sum(1*1, 2*2, 3*3)) =>
print(1+4+9) => 14 ☺

Answer 3

2**2= 2*2=4
2**3= 2*2*2=8

Answer 4

tristach605 Your lambda says x**2, not x**3 or x**x

Answer 5

Thanks! Any idea why range is only 1-3 (not 1-4)?

Also, 2**2 is 4? 2x2x2 should be 8, shouldn't it?

Sorry for the confusion and thanks for any help you could provide.

Answer 6

You have written 3**3=27. But it should be 3**2=9. Also you have a syntax error at line 2. You have not closed the ()....

Answer 7

2**2=2x2=4
How do you come to 2x2x2?

Answer 8

I have since edited the post as AZT noted.
