如何利用 Pandas 获取比当前行值更大的数据之间的个数？

import numpy as npimport pandas as pdvalues = [[5.5, 2.5, 10.0], [2.0, 4.5, 1.0], [2.5, 5.2, 8.0],[4.5, 5.8, 4.8], [4.6, 6.3, 9.6],[4.1, 6.4, 9.0],[5.1, 2.3, 3],[5.1, 2.3, 11.1],[5.1, 2.3, 10],[5.1, 2.3, 11.1],[5.1, 2.3, 20],[5.1, 2.3, 31],[5.1, 2.3, 5]]df = pd.dataframe(values, columns=['col1', 'col2', 'col3'])count_larger = lambda x: np.sum(x > x[-1])df['col4'] = [count_larger(df[:i + 1]['col3'].values) for i in range(len(df))]print(df)
