I'm having some trouble reading multiple data types from a single text

say I had a file with names and numbers:
bob
100
sue
250
jim
300
I have a few problems. I know how to convert the lines into an integer
but I don't know how to iterate through all the lines and just get the
integers and store them or iterate through the lines and just get the
names and store them.
please help.

You could do it with a list comprehension
>>> names = []
>>> numbers = []
>>> [numbers.append(int(line.strip())) if line.strip().isdigit() else
names.append(line.strip()) for line in open('test.txt','rb') if
line.strip()]
[None, None, None, None, None, None]
>>> names, numbers
(['bob', 'sue', 'jim'], [100, 250, 300])
The list comprehension would unfold to
for line in open('test.txt', 'rb'):
if line.strip():
if line.strip().isdigit():
numbers.append(line.strip())
else:
names.append(line.strip())
And from there you can do what you like with the lists.
