What mean this error?

Question

EOFError: EOF when reading a line

Answer 1

Show the code please

Answer 2

If you run it in Sololearn, you have to provide all the needed input at once, as the program only asks you once for it -- before executing the code.

You provide the input in separate lines, like this:
5
/
9

>>> (the output will be)
0.55555

Answer 3

It means the interpreter expected yet something in your code and didn't find it :)

Perhaps an open parenthesis?

Answer 4

No parentheses are closed

Answer 5

num1 = float(input("Enter first number: "))
operator = input("Enter operator: ")
num2 = float(input("Enter second number: "))

if operator == "+":
print(num1 + num2)
elif operator == "-":
print(num1 - num2)
elif operator == "/":
print(num1 / num2)
elif operator == "*":
print(num1 * num2)
else:
print("Invalid operator")
