Example: iteritems() example

The example below demonstrates the usage of iteritems() function.

import pandas as pd
import numpy as np

info = pd.DataFrame({
  "Salary": [25, 24, 30, 28, 25],
  "Bonus": [10, 8, 9, np.nan, 9],
  "Others": [5, 4, 7, 5, 8]},
  index= ["2015", "2016", "2017", "2018", "2019"]
)

print(info,"\n")

for label, content in info.iteritems():
  print(f'label: {label}')
  print(f'content: \n{content}')
  print()

The output of the above code will be:
