cool! i love the idea and no i wont tell anyone
for i in a:
b=set(i[:len(i)//2])
c=set(i[len(i)//2:])
d=list(b.intersection(c))[0]
p+=o.index(d)
p=0
for i in range(len(a)//3):
e.append(a[i*3:i*3+3])
for i in e:
t=list(set(i[0]).intersection(set(i[1]).intersection(set(i[2]))))
p+=o.index(t[0])
Flaggers 
a=list(map(lambda x:x.split(","),a))
def contains(a,b):
A=list(map(int,a.split("-")))
B=list(map(int,b.split("-")))
return A[0]<=B[0] and A[1]>=B[1]
def contains(a,b):
A=list(map(int,a.split("-")))
B=list(map(int,b.split("-")))
sa=set(range(A[0],A[1]+1))
sb=set(range(B[0],B[1]+1))
return len(list(sa.intersection(sb)))>0
p=0
for i in a:
if contains(i[0],i[1]) or contains(i[1],i[0]):
p+=1
Still didn't make it to the leader board

Aaaaah, I'm late but finally got around to tackle day 3
Here's what I did for
and here's
Nice use of pipe and I like the early conversion to Unicode to avoid case issues
