Python使用字典中的随机值填充多个列

import random

data = {'col1': random.randint(1, 100),
        'col2': random.choice(['A', 'B', 'C']),
        'col3': random.uniform(0.0, 1.0)}

import pandas as pd

df = pd.DataFrame(columns=['col1', 'col2', 'col3'])
df = df.fillna(data)

import random
import pandas as pd

data = {'col1': random.randint(1, 100),
        'col2': random.choice(['A', 'B', 'C']),
        'col3': random.uniform(0.0, 1.0)}

df = pd.DataFrame(columns=['col1', 'col2', 'col3'])
df = df.fillna(data)
