python little ping script
Hi everyone,

I'm a newby in the python languages, and I try to make some parallels to shell.
My question is how ca I give the information to python that the line 3 "r=...." the string "line" is a variable.

Code:
import os, re
line = "localhost"
r = "".join(os.popen("ping line -c 1").readlines())
print r
if re.search("64 bytes from", r):
 print "Site is reachable"
else:
 print "Site is not reachable"

because in this case the ping toll try to reach the hostname line and the host is unknown.

that should be:

Code:
import os, re
line = "localhost"
r = "".join(os.popen("ping $line -c 1").readlines())
print r
if re.search("64 bytes from", r):
 print "Site is reachable"
else:
 print "Site is not reachable"

is ther any way to solve this issue in python ?

I found a solution

Code:
line = "localhost"
cmd = "ping -c1 " + line
r = "".join(os.popen(cmd).readlines())

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
