I have n=4 and P = [1,2,3,4]  , plus the next dictionnaries 

d1= {m+10: 0 for m in range(12)}
d = {0:0, 1:15,2:30,3:15,4:30,5:15,6:30,7:15,8:30,9:0,**d1}
c = {(i,j): np.round(np.hypot(xc[i]-xc[j], yc[i]-yc[j])) for i in N for j in N }
t = {a : np.round (c[a] / v) for a in c } # distance over velocity 60km/h

L = { i: t[i,n+i]*2 for i in P}
infeasible-path1 = [(i, n+j) for i in P for j in P if d[j] + t[j,i] + d[i] + t[i,(n+j)] + d[n+j] + t[n+j, n+i] + d[n+i] > L[i]]

 

'''

When I try to print(len(infeasible-path1)), it gives me SyntaxError: can't assign to the operator.?????!!!!!!

An additional issue is how can I write in the coding mode? .......can not see any icon or a sign for that.

  I caught my mistake, infeasible-path1 should be infeasible_path1

  Thanks a lot.
