ValueError：错误的文件描述符

Question

I'm trying to write a script in which I need to get the terminal size in order to adjust the output text width appropriately. I use this lines:

import os
x = os.get_terminal_size().lines

which results in getting this error:

ValueError: bad file descriptor

What's wrong with the code?

Answer 1

Try this:

import sys
import os
try:
    cols,rows = os.get_terminal_size(0)
except OSError:
    cols,rows = os.get_terminal_size(1)

sys.stdout.write('cols:{} \n rows:{} \n'.format(cols,rows))
