EOFError in input function

I am troubled because I do not understand the meaning of Python error message.
I'm sorry to ask you a beginner's question, but please help me.

input function of the program chap2.py 「Please enter: 」 and you will see the following in the terminal:

Please enter: I want to quit now
Traceback (most recent call last):
  File "chap2.py", line 2, in <module>
    US>parrot=input("Please enter:")
EOFError

In Python 3.7.3, you entered:

parrot=input("Please enter:")
print(parrot)
)

I changed the terminal character code to utf-8 because it was garbled by default.
Active code page: 65001

In Edit in setting json of terminal integrated shell args windows, we added the following code:

"terminal.integrated.shellArgs.windows":[
"- NoExit",
"chcp",
"65001"
],

I started the command prompt from the folder and tried it, but I got a similar error message.

I'm in a lot of trouble.Thank you very much for your instruction.
