Answer 3

def nested_int_list_from_file(file):
f = open(file)
read = f.read()
lines = lines.strip(‘\n’)
line = lines.split(‘\n’)

return line

- i got [‘2,1,3’, ‘3,1,3’, ‘2,9’]

then i tried adding:
for i in line:
new_line = int(i)
return new_line

but it wont convert to integers

Answer 4

the file is written like this:

2,1,3
3,1,3
2,9

Answer 5

s=eval(input("Enter list:"))
final,l=[],[]
for i in s:
a=i.split(",")
for j in a:
l.append(int(j))
final.append(l)
print(final)

Answer 9

The crudest logical approach is to do something like:

a = ['2,1,3', '3,1,3', '2,9'] # to [[2,1,3], [3,1,3], [2,9]]
b = len(a)
c = []
d = []
e = []
f = []

c.append(a[0])
d.append(a[1])
e.append(a[2])
f = [c, d, e]

print(f)

This will give you the result. Hope it gives you an idea of what you want to achieve
