Print current python file error line

During the python error debugging process, it is sometimes necessary to print the error line of the current python file. Here is a method:

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)

Print the error line of execfile:

try ; 1][1])

Use the reflection mechanism to call the function and print the callee’s error line and error message

try:

callfunc.callfunc(myklass,strmethod,params)

except :

print '= == STEP ERROR Info Start'

Import Traceback

Traceback.print_exc ()

Print '=== Step Error Info End'
