打印当前python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'
