Handle Exception in Python

Question

Code:

genders=[]
      for image in os.listdir('Face'):
        try:
          gender = int(image.split('_')[1])
        except ValueError:
          pass
      genders.append(gender)

Trying to add int values of string in list.
Raises Value error

ValueError: invalid literal for int() with base 10: ”

so for example : imageName_1 get that one and add to a list. but sometimes after _ there is no number. so i want to catch that image and delete it but don’t want to stop the iteration.

Answer 1

Using continue statement will allow you to continue iteration.

genders=[]
for image in os.listdir('Face'):
   try:
       gender = int(image.split('_')[1])
   except ValueError:
       continue
   genders.append(gender)

gender is defined in the try clause only, so you can’t append it to genders, and you don’t need to (because you want to delete the file), so this line should be in the try clause also:

genders=[]
for image in os.listdir('Face'):
    try:
        gender = int(image.split('_')[1])
        genders.append(gender)
    except ValueError:
        # delete file
        os.remove(image)

Maybe a small change in the code will work

genders=[]
    for image in os.listdir('Face'):
        try:
            gender = int(image.split('_')[1])
            genders.append(gender)
        except ValueError:
            pass

import os
genders=[]
for image in os.listdir('Face'):
  try:
    genders.append(int(image.split('_')[1]))
  except (ValueError, IndexError):
    try:
      os.remove(image)
    except OSError:
      pass
