在Pandas DataFrame中创建一列，对所有大于或小于当前行的行进行计数

import pandas as pd

data = {'A': [1, 2, 3, 4, 5],
        'B': [6, 7, 8, 9, 10]}
df = pd.DataFrame(data)

df['Count'] = 0

for i, row in df.iterrows():
    count = 0
    for j, val in row.iteritems():
        if j != 'Count':
            if val > row[j]:
                count += 1
            elif val < row[j]:
                count -= 1
    df.at[i, 'Count'] = count

print(df)
