Reordering arrays
... would be:

ar.move(0,3);
alert(ar) // 2,3,4,1,5

Which is faster in Python: x**.5 or math.sqrt(x)?
...
math.sqrt(x) is significantly faster than x**0.5.
import math
N = 1000000
%%timeit
for i in range(N):
z=i**.5
10 loops, best of 3: 156 ms per loop
%%timeit
for i in range(N):
z=math.sqrt(i)
10 loops, best of 3: 91.1 ms per loop

How do Python's any and all functions work?
...or example,

Here, (not (i % 6) for i in range(1, 10)) is a generator expression which returns True if the current number within 1 and 9 i...
