Thonny error

[Bope]

My son and I are learning python with a Pi3. Everything was working fine until we started getting errors after a simple input statement like x = input ('Name?') We are using Thonny. Here is the error we are getting

Can you post here the python code you are trying to run?

Here is the code
print ('hi')
w = input ('Name')
print (w)
