Python非ASCII字符错误

Question

I Have a written a small python code with intention of getting my system information and disk size. I am using subprocess module here.

[root@localhost code]# cat pysys.py
#!/usr/bin/python
import subprocess;

def sysinfo():
        subprocess.call(“uname –a”,shell=True)
def diskinfo():
        subprocess.call(“df –h”,shell=True)
def main():
        sysinfo()
        diskinfo()
main()

When ever I am trying to execute , I am getting the error as

[root@localhost code]# python pysys.py
  File "pysys.py", line 5
SyntaxError: Non-ASCII character '\xe2' in file pysys.py on line 5, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
[root@localhost code]#

EDIT:

[root@localhost code]# cat pysys.py
#!/usr/bin/python
import subprocess;

def sysinfo():
        subprocess.call("uname –a",shell=True)
def diskinfo():
        subprocess.call("df –h",shell=True)
def main():
        sysinfo()
        diskinfo()
main()

[root@localhost code]# python pysys.py
  File "pysys.py", line 5
SyntaxError: Non-ASCII character '\xe2' in file pysys.py on line 5, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
[root@localhost code]#

Am I missing anything ? Please let me know.

Thank you.

Answer 1

Your quotes look weird, use shift-2 and nothing else, ie a "

ascii 34, hex 22, octal 042

If you are using vim as your editor, you can check value under cursor using ga

Answer 2

It seems you are using non-ASCII character.( – / ' ). It usually happens when you copy content from somewhere.

So modify your code as below:

#!/usr/bin/python
import subprocess;

def sysinfo():
        subprocess.call("uname -a",shell=True)
def diskinfo():
        subprocess.call("df -h",shell=True)
def main():
        sysinfo()
        diskinfo()
main()

The difference is just - . You are using – .
