Pandas: Make a Data Frame with random floats

pandas used to have a private pd._testing.makeDataFrame() function to return a DataFrame containing random floats, but this and similar helpers in pandas._testing were removed entirely in later pandas 2.x releases. The public API equivalent is straightforward:

>>> import numpy as np
>>> import pandas as pd
>>> pd.DataFrame(np.random.randn(10, 5), columns=list("ABCDE"))
