EOF Error occurs when trying to give a user input

Question

I am learning python and have the following code in test.py:

string = input()
print(string)

Contrary to tutorials, it gives me an error:

    string = input()
EOFError: EOF when reading a line

I have no idea what I do wrong here! Any help appreciated!

You seem to have an EOFError exception when running your code. EOFError is short for "End-of-File Error." This error occurs when Python has reached the end of user input without receiving any input.

The reason that EOFError occurs is that Python attempts to print out your input in variable string when no data is given.

Generally, this error shouldn't pop up when you press your Enter key as input as it registers the variable as a string in your code. It can be manually triggered with the following keystrokes:

• Windows: Ctrl + Z -> Enter
• macOS/Linux: Ctrl + D -> Enter

I'd recommend rerunning your program with the same code as it is not likely for an EOFError to appear. Try to avoid using the above keystrokes when the program requires input so the error doesn't appear.

If you don't want to see the error in your program, try handling the error and performing another action like printing a string. The code block I've typed prints "no data provided to input function" if an EOFError exception occurs.

try:
     string = input()
     print(string)
except EOFError:
     print("no data provided to input function")

If you are a beginner, this snippet won't be needed as you start in Python. Just for a friendly tip, you should name variables relevant to their purpose (ex: naming the sum of two numbers sum1 instead of integer). Naming it after its datatype is okay for very short-term uses but AFAIK is not conventional in any coding language.
