That's not how you write a map. Here's how you write a map:
J=[0,1,2,3]
S=[4,5,6,7]
def T(x):
return S[x]
print [(j,T(j)) for j in J]

we live in the age of giving things really fucking stupid names

I. Fucking. Love. Science.

I think the s and j are initials of their names, and T is a function of time? Who the fuck uses euro signs anyway
It's babys first set theory with make do operators.
It is correct though
He should have said "let f : J be a bijection onto S such that f[J] = S"
much more romantic

correct but redundant
F'(s)=j so I lie tangent to your curves ;)))
