get random sample from dataframe python code example

Example 1: pandas sample seed

>>> df.sample(frac=0.5, replace=True, random_state=1)
      num_legs  num_wings  num_specimen_seen
dog          4          0                  2
fish         0          0                  8

Example 2: pandas random sample

# n: number of rows to be extracted randomly
# random_state fixed for reproducibility
# replace = True for extraction with replacement

df.sample(n=3, random_state=42, replace=False)
