我怎么能发现,在终点线之前,在使用假装的交火壳中,有线性。 (单位:80)
您可使用tput,用于查询终端现有线路和栏目的数量。 您可使用subprocess.P open:
>>> import subprocess
>>> tput = subprocess.Popen([ tput , cols ], stdout=subprocess.PIPE)
>>> int(tput.communicate()[0].strip())
180
这一原则也可适用于以下变量:$COLUMNS/code>:。 gregseth:
>>> tput = subprocess.Popen([ echo $COLUMNS ], shell=True, stdout=subprocess.PIPE)
>>> int(tput.communicate()[0].strip())
180
最后,如果你是大韩民国使用proposed。 Ignacio Vazquez-Abrams随后指出,你需要作三次发言,而不是一次:
>>> import curses
>>> curses.setupterm()
>>> curses.tigetnum( cols )
180
如果该终点站重新缩编,则setupterm。 需在新终端码头前使用>tigetnum查询。
I don t know specifically in python,
but in a shell the environment variable $COLUMNS contains the information you want.
www.un.org/Depts/DGACM/index_spanish.htm 由于python3.3,还有另一种办法可以确定终点站的规模。
import os
columns = os.get_terminal_size(0)[0]
lines = os.get_terminal_size(0)[1]

>>> import sys,struct,fnctl,termios
>>> fd = sys.stdin.fileno()
>>> s = struct.pack("HH", 0,0)
>>> size=fcntl.ioctl(fd, termios.TIOCGWINSZ,s)
>>> struct.unpack("HH", size)[-1]
