编写大熊猫DataFrame的最快方法

import pandas as pd

data = {'列名1': [值1, 值2, 值3, ...],
        '列名2': [值1, 值2, 值3, ...],
        '列名3': [值1, 值2, 值3, ...],
        ...}

df = pd.DataFrame(data)

import pandas as pd

data = [[值1, 值2, 值3, ...],
        [值1, 值2, 值3, ...],
        [值1, 值2, 值3, ...],
        ...]

columns = ['列名1', '列名2', '列名3', ...]

df = pd.DataFrame(data, columns=columns)
