Updating and displaying images on pygame

Question

I'm trying to write a code in pygame that uses speech recognition and different images. The code should function as follow: The user will be shown different images of animals and will have to say what they are seeing. After that, the speech recognization will take the user's input and convert it to a string and compare it with the string associated with the shown image. And determine whether the answer is correct or incorrect and move to the other image.

The difficulty I'm having right now are uploading and updating the image each time the user provide an answer

Answer 1

Create a list of images, rather than a list of filenames:

image_list = []
for filename in glob.glob('MG/*.jpg'):
    image_list.append(pygame.image.load(filename))

Create a list of names. The list of names has to correspond to the list of images:

name_list = ['dog', 'cat', 'rat']

Find the index of the element in name_list, which matches text. There are different ways to do that. See Finding the index of an item in a list. For instance:

try:
    index = name_list.index(text)
except ValueError:
    index = -1

---

Example:

image_list = []
for filename in glob.glob('MG/*.jpg'):
    image_list.append(pygame.image.load(filename))

name_list = ['dog', 'cat', 'rat'] 

text = r.recognize_google(audio)

try:
    index = name_list.index(text)
except ValueError:
    index = -1

gameDisplay.fill(white)
if 0 <= index <= len(image_list): 
    gameDisplay.blit(image_list[index], (130,0))
pygame.display.update()

if index > 0:
    message_display('good job')
else:
    message_display('wrong')
