dataframe.dropna()删除行

dataframe.dropna()删除行的操作是指通过调用dropna()函数来删除dataframe中含有空值的行。在这个函数中，使用默认的参数值即可实现删除含有空值的行的操作。具体而言，dropna()函数中的axis参数设置为0或'index'，表示按行删除；how参数设置为'any'，表示该行只要有一个以上的空值就会被删除。其他参数如thresh、subset和inplace可以根据需求进行设置。通过调用dropna()函数并传入以上参数，即可实现删除dataframe中含有空值的行的操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
