打印当前.py文件错误行:
import sys

a = [1,2]
print a[3]
except:
s=sys.exc_info()
print "Error '%s' happened on line %d" % (s[1],s[2].tb_lineno)
 
打印execfile的打印错误行:
try:
execfile("tprint.py")
except Exception, info:
#print info[1]
print "Error '%s' happened on line %d" % (info[0], info[1][1])
 
 
利用反射机制,调用函数,打印被调用方的错误行及错误信息
try:
callfunc.callfunc(myklass,strmethod,params)
except :
print '=== STEP ERROR INFO START'
import traceback
traceback.print_exc()
print '=== STEP ERROR INFO END'
