Which function in pandas is used to randomly sample fractions of rows from a DataFrame?sample()random()frac()choose()

The function used in pandas to randomly sample fractions of rows from a DataFrame is sample(). Here is how you can use it:

1. First, import pandas library:

import pandas as pd

2. Create a DataFrame:

df = pd.DataFrame({'A': range(1, 6), 'B': range(10, 60, 10)})

3. Use the sample() function to randomly sample fraction of rows. For example, to sample 50% of the data:

df_sample = df.sample(frac=0.5)

In the above code, frac=0.5 means it will return 50% of the data. If you want to return n number of items from the dataframe, use n parameter. For example, df.sample(n=3) will return 3 random rows from the dataframe.

Note: The random(), frac(), and choose() are not functions used to sample data in pandas.
