EOF?

Question

So I just finished the second part of the python course and I tried making a calculator on my PC and it works perfectly but on my phone it tells me that there an EOF ERROR what does that mean?

Answer 1

End Of File Error. Trying to access more values from a file or input than is there

Answer 2

yeah I think I figured it out: on my PC it would tell me to input one at the time but on my phone it wants me to input all together.
like on my PC it asks: select ADD SUBTRACT MULTIPLY OR DIVIDE then it asks me for First number and then second but on my phone i have to pick everything at the same time and write it down like this:
ADD
