Print the current Python file error line

In the Python error debugging process sometimes need to print the current Python file error line, below to describe the method:

Import Sys

Try

A = [+]

Print A[3]

Except

S=sys.exc_info ()

Print "Error '%s ' happened on line%d"% (S[1],s[2].tb_lineno)

Print error line for printing execfile:

Try

ExecFile ("tprint.py")

Except Exception, info:

#print Info[1]

Print "Error '%s ' happened on line%d"% (Info[0], info[1][1])

Use reflection mechanism, call function, print the wrong line of callee 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 '
