    打印当前.py文件错误行:
    import sys
    try:
    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'
