Next, consider the following function definition, which includes one blank (designated by _._A___) to be filled in: \( \begin{array}{l} \text { def } f 2(\text { dct }): \\ \text { for } x \text { in dct: } \\ \text { print (_____) }\end{array} \) Fill in the blank with a Python expression that, if used to replace _-_ \( _{\text {_-_ }} \) in f2, will cause f2 to exhibit the same behavior as f1 for all input dictionaries
