Back to all questions 10
Question Write code that just produces single True/False as a result for the presence of missing values in whole DataFrame namely df.
import pandas as pd
data = {'A': [1, 2, None, 4], 'B': [None, 5, 6, 7], 'C': [8, 9, 10, 11]}
df = pd.DataFrame(data)
has_missing_values = False
for column in df.columns:
for value in df[column]:
if pd.isnull(value):
has_missing_values = True
break
print(has_missing_values)True
import
