将4行数据读入一行pandas数据帧

import pandas as pd

data = [
    {'col1': value1, 'col2': value2, 'col3': value3, 'col4': value4},
    {'col1': value5, 'col2': value6, 'col3': value7, 'col4': value8},
    {'col1': value9, 'col2': value10, 'col3': value11, 'col4': value12},
    {'col1': value13, 'col2': value14, 'col3': value15, 'col4': value16}
]

df = pd.concat([pd.DataFrame(data[i], index=[0]) for i in range(len(data))], ignore_index=True)
