except:
print "Error occur!"
pass

if len(sys.argv) > 1 :
for m_dir in sys.argv[1:]:
print m_dir
funCount(m_dir)
else :
funCount(".")

print "files count : ",filesCount
print "lines count : ",linesCount

raw_input("Press Enter to continue")

使用方法
1、针对本目录

代码如下:

./count.py

2、统计多个目录

代码如下:

./count.py /tmp ~
