pandas每列最大值

要找到pandas中每列的最大值，可以使用DataFrame的max()方法。以下是一个示例代码:

import pandas as pd

df = pd.DataFrame({
    'id': ['x', 'y', 'z'],
    'a': [3, 4, 2],
    'b': [0, 5, 7],
    'c': [1, 0, 1]
})

max_values = df.max()

在这个例子中，`max_values`将会包含每列的最大值。你可以通过索引来访问每列的最大值。例如，`max_values['a']`将会返回列'a'的最大值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
