Thank you for your response!
The problem is now in the following codes:
1.
f = open("list2.txt")
l1 = f.readline()
ls1 = l1.split(" ")
l1
gives:
Traceback (click to the left for traceback)
...
IOError: [Errno 2] No such file or directory: 'list2.txt'
Similarly, the eval function, eval(ls1), in (1) and the following code
(2) causes the previous error.
2.
f = open('list2.txt')
varList = [x.split(' // ') for x in f.readlines()]
I have the file list2.txt at SageRoot.
