It is saved in a file name pcb.dat. With the following code
import csv
file=r'C:\Users\Cyrille\pcb.dat'
reader=csv.reader(open(file))
L=[]
for row in reader:
L.append(row)
show(L)
I can import it in SM. But it's a list composed of strings. And I want a matrix beginning at the second line with Real or Rational numbers. How can I obtain this littel and simple (but absolutely necessary) operation ? Therer is a lot of questions on that subject but I cannot see in the answer the one I am searching.
