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()
