What's the difference between lists enclosed by square brackets and parentheses in Python?
...es.
A list is mutable, meaning you can change its contents:
>>> m>x m> = [1,2]
>>> m>x m>.append(3)
>>> m>x m>
[1, 2, 3]
while tuples are not:
>>> m>x m> = (1,2)
>>> m>x m>
(1, 2)
>>> m>x m>.append(3)
Traceback (most recent call last):
File "<stdin>", line 1, in ...
How can the Euclidean distance be calculated with NumPy?
...
There's a function for that in SciPy. It's called Euclidean.
Em>x m>ample:
from scipy.spatial import distance
a = (1, 2, 3)
b = (4, 5, 6)
dst = distance.euclidean(a, b)

How to “properly” print a list?
...
In Python 2:
mylist = ['m>x m>', 3, 'b']
print '[%s]' % ', '.join(map(str, mylist))
In Python 3 (where print is a builtin function and not a syntam>x m> feature anymore):
mylist = ['m>x m>', 3, 'b']
print('[%s]' % ', '.join(map(str, mylist)))
Both return:

Test if lists share any items in python
... Python, searching them is O(1) (see here for more information about complem>x m>ity of operators in Python). Theoretically, this is O(n+m) on average for n and m objects in lists a and b. But 1) it must first create sets out of the lists, which can take a non-negligible amount of time, and 2) it suppose...
