如何为DataFrame列的每个浮点值生成相同的随机数？

import numpy as np
import pandas as pd

df = pd.DataFrame({'A': [1.0, 2.0, 3.0, 4.0, 5.0]})

random_number = np.random.rand()

df['A'] = random_number

import numpy as np
import pandas as pd

df = pd.DataFrame({'A': [1.0, 2.0, 3.0, 4.0, 5.0]})
random_number = np.random.rand()
df['A'] = random_number
