<p>안녕하세요.</p>
<p>melt 후에 아래와 같이 변수에 지정해 주어야 하는데 해당 과정이 누락되었어요.</p>
<p>아래와 같이 시도해 보세요!</p>
<p><span style="color: #000000;"><span style="background-color: #ffffff; font-family: 'Noto Sans KR'; font-size: 15px; letter-spacing: -0.3px; white-space: pre-wrap;"><span style="color: #ba372a;"><strong>df_first_melt</strong></span> = </span><span style="font-family: 'Noto Sans KR'; font-size: 15px; letter-spacing: -0.3px; white-space: pre-wrap; background-color: #ffffff;">df_first.melt(id_vars="지역", var_name="기간", value_name="평당분양가격")</span></span></p>
