subject [CPyUG] 请问下如何在python中获得命令行终端的宽度？

在写python命令行程序的时候，如果能获取当前命令行终端的长度，就可以根据这个值来格式化输出的内容，使得输出的内容更加整洁美观。

宽度

我找到解决方法了，请参见下面的程序： get_terminal_width.py`

   1 import commands
   2 def get_terminal_width_resize():
   3     c = commands.getoutput('resize').split('\n')
   4     c = [x for x in c if x.startswith('COLUMNS=')]
   5     if c:
   6         c = c[0]
   7         dummy, c = c.split('=', 1)
   8         if c[-1] == ';':
   9             c = c[:-1]
  10     if c:
  11         return int(c)
  12     else:
  13         return None
  14         
  15 print get_terminal_width_resize()

高度

同样可以得到获得终端高度的程序：

   1 import commands
   2 
   3 def get_terminal_height():
   4 
   5     c = commands.getoutput('resize').split('\n')
   6     c = [x for x in c if x.startswith('LINES=')]
   7 
   8     if c:
   9         c = c[0]
  10         dummy, c = c.split('=', 1)
  11         if c[-1] == ';':
  12             c = c[:-1]
  13     if c:
  14         return int(c)
  15     else:
  16         return None
  17         
  18 print get_terminal_height()
