How does functools partial do what it does?
..., fnx()) for c in range(10) ]
target = (2, 4)
import math
def euclid_dist(v1, v2):
x1, y1 = v1
x2, y2 = v2
return math.sqrt((x2 - x1)**2 + (y2 - y1)**2)
To sort this data by distance from the target, what you would like to do of course is this:
data.sort(key=euclid_dist)
but you ca...

...equire the uses of spaces. So, basically, the following are identical:

101V=100
as
10 1V = 100
or as
101 V = 100
or as
1 01V = 100
So, this was made illegal.
