In fin.read (), 3 lines are printed () at a time.
In the above case, it doesn't seem to make sense to use the with syntax.
There seems to be readline (). https://stackoverflow.com/questions/7472839/python-readline-from-a-string

import io
emuCsv = """1,2,3
4,5,6
7,8,9"""
print('begin')
fin = io.StringIO(emuCsv)
print(fin.readline(),end='')
print(fin.readline(),end='')
print(fin.readline())
print('end')
run
begin
1,2,3
4,5,6
7,8,9
end
You can run readline () a fixed number of times. Unknown about EOF.
