Pandas: First Steps

bookThe `sample()` Method

The sample() method returns a random row from the DataFrame by default.

There are two optional named parameters which can be used to specify how many random rows to fetch:

  • n: Specifies the exact number of random rows to fetch;
  • frac: Specifies the fraction or percentage of the total rows to fetch. For example, frac=0.2 will return 20% of the total rows;

              
123456789101112

            
import pandas as pd

# Sample DataFrame
df = pd.DataFrame({
    'Coffee': ['Espresso', 'Latte', 'Cappuccino', 'Americano', 'Macchiato'],
    'Price': [2.5, 3.5, 3.0, 2.8, 3.2],
    'Availability': ['Yes', 'Yes', 'Yes', 'Yes', 'No']
})

print("Get 2 random rows from the DataFrame:")
random_rows = df.sample(n=2)
print(random_rows)
copy
