• iterrows()方法：返回行

df = pd.DataFrame([('E146', 100.92, '[-inf ~ -999998.0]'),('E138', 107.92, '[-999998.0 ~ 2]'),
                   ('E095', 116.92, '[1.5 ~ 3.5]')],columns = ['name', 'score', 'value'])
df

for row_index, row in df.iterrows():
    print(row)
    break

• iteritems()方法：返回列

for col_index, col_value in df.iteritems():
    print(col_value)
    break
