  • This is my code : with open("vocabulary.txt", mode = 'r') as f: words ={} while s:=f.readline(): words[list(eval(s).keys())[0]] = list(eval(s).values())[0] Commented Nov 11, 2022 at 1:55
  • Exactly as the error message indicates: eval is for expressions, not statements (such as an assignment). It cannot accept the s= part. That said: Do not ever use eval (or exec) on data that could possibly come from outside the program in any form. It is a critical security risk. You allow the author of the data to run arbitrary code on your computer. Commented Nov 11, 2022 at 1:57
  • Thank you so much Karl. Could you please explain how can overcome it please, Commented Nov 11, 2022 at 1:58
  • Please see the linked duplicate. Also consider where your data is coming from and why it looks the way it does. Commented Nov 11, 2022 at 2:01
  • Since i am a beginner in Python, I couldn't completely understand the way forward, Karl. below is my code expression and i am stuck to proceed further. Please help. with open("vocabulary.txt", mode = 'r') as f: words ={} while s:=f.readline(): words[list(eval(s).keys())[0]] = list(eval(s).values())[0] Commented Nov 11, 2022 at 2:05
