Detection of the word working randomly

[TroTro]

Hi everyone,

I am a begginer of python and I start a project for myself. This project is for Pokemon games, and i need to get the name of pokemon i am fighting against. 
The problem is that sometimes it works very well and if i try another time it detects the empty string.
For instance, this is the picture i capture to extract the pokemon name. It should extract "cadoizo" and even if it is not accurate, I coded something to select the most similar pokemon name. 
I just don't want an empty string. Do you have some solution? 

That's the part of my code doing it:

# Spécifiez les coordonnées de la région de l'écran à capturer (x, y, hauteur, largeur)

region = (300, 70, 280, 68)

screenshot = pyautogui.screenshot(region=region)

# Convertissez la capture d'écran en une image Pillow

image = Image.frombytes("RGB", screenshot.size, screenshot.tobytes())

image.show()

# Utilisez pytesseract pour extraire du texte de l'image

text = pytesseract.image_to_string(image)

morceaux = text.split(' ', 1)

text = morceaux[0]

# Affichez le texte extrait

print("Texte extrait de l'image:", text)
