Pandas Data Series: Check inequality over the index axis of a given dataframe and a given series
Pandas: Data Series Exercise-40 with Solution
Write a Pandas program to check inequality over the index axis of a given dataframe and a given series.
Sample Solution :
Python Code :
import pandas as pd
df_data = pd.DataFrame({'W':[68,75,86,80,None],'X':[78,75,None,80,86], 'Y':[84,94,89,86,86],'Z':[86,97,96,72,83]});
sr_data = pd.Series([68, 75, 86, 80, None])
print("Original DataFrame:")
print(df_data)
print("\nOriginal Series:")
print(sr_data)
print("\nCheck for inequality of the said series & dataframe:")
print(df_data.ne(sr_data, axis = 0))
Sample Output:
Original DataFrame: W X Y Z 0 68.0 78.0 84 86 1 75.0 75.0 94 97 2 86.0 NaN 89 96 3 80.0 80.0 86 72 4 NaN 86.0 86 83 Original Series: 0 68.0 1 75.0 2 86.0 3 80.0 4 NaN dtype: float64 Check for inequality of the said series & dataframe: W X Y Z 0 False True True True 1 False False True True 2 False True True True 3 False False True True 4 True True True True
Explanation:
df_data = pd.DataFrame({'W':[68,75,86,80,None],'X':[78,75,None,80,86], 'Y':[84,94,89,86,86],'Z':[86,97,96,72,83]}); sr_data = pd.Series([68, 75, 86, 80, None])
The above code creates a Pandas DataFrame object 'df_data' containing four columns ('W', 'X', 'Y', 'Z') and five rows, and a Pandas Series object 'sr_data' containing the same values as the 'W' column of the DataFrame.
df_data.ne(sr_data, axis = 0) : Here .ne() method is used to compare the dataframe df_data with the series sr_data. ne stands for "not equal". The axis=0 parameter tells pandas to compare the rows of the dataframe and the series. The resulting dataframe will have the same shape as df_data and will contain boolean values indicating whether the corresponding elements in df_data are not equal to the values in sr_data.
