Python syntax for an empty while loop

问题

I have written this:

    while file.readline().startswith("#"):
        continue

But I suspect the continue is unnecessary? What is the correct syntax for what i'm trying to achieve?

回答1:

while file.readline().startswith("#"):
    pass

This uses the pass statement :

The pass statement does nothing. It can be used when a statement is required syntactically but the program requires no action.
