6.Create a dataframe and print it along with their index using iteritems().
Solution :-
import pandas as pd
def df_operations():
sc_4yrs={2016:{'Virat Kohli':2595,'Rohit Sharma':2406,'Shikhar Dhawan':2378},
2017:{'Virat Kohli':2818,'Rohit Sharma':2613,'Shikhar Dhawan':2295},
2018:{'Virat Kohli':2735,'Rohit Sharma':2406,'Shikhar Dhawan':2378},
2019:{'Virat Kohli':2455,'Rohit Sharma':2310,'Shikhar Dhawan':1844}}
df=pd.DataFrame(sc_4yrs)
print(df)
print("------------------------------------------------------------------------")
for (year,runs) in df.iteritems():
print("Year:",year)
print(runs)
df_operations()
Output :-
