``... | 2019/08/04 | ['https://Stackoverflow.com/questions/57350378', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/6553328/'] | Using a list comprehension to hide a for loop is kind of cheating given that the result produced by the comprehension is not the sorted list. But if you're going to do that, you might want to avoid building a list of None elements by performing the swaps in the condition rather than as the output value.
For example:
... | ```
def bubblesort(l):
[[l.insert(j+1, l.pop(j)) for j in range(i) if l[j] > l[j+1]] for i in range(len(l)-1,0,-1)]
return l
```
I use the `l.insert(j+1, l.pop(j))` to swap the elements in the list. The rest are just the nested loops. |

Up to here it is OK. Then you cannot say that $E[(\frac{1}{n}\sum\_{i = 1}^nX\_i)^2]=E[\frac{1}{n}\sum\limits\_{i = 1}^nX\_i]E\cdot[\frac{1}{n}\sum\limits\_{i = 1}^nX\_i]$. It is just $\frac1{n^2} E(\sum\limits\_{i = 1}^nX\_i)^... | For independent RV's one has
$$ Var(\sum\_1^n X\_i) = \sum\_1^n Var(X\_i)$$
hence
$$ Var(\frac1n Y) =\frac1{n^2} n Var(X\_1)=\frac1n Var(X\_1) $$
since $X\_i$'s are identically distributed. |
