空while循环的Python语法

Question

我写过：

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

但我怀疑continue是不必要的？对于我想要实现的目标，正确的语法是什么？

Answer 1

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

它使用pass语句：

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