How to calculate SUM if cells not equal to something ?

formula -->

=SUMIF($D$5:$D$29,H5,$E$5:$E$29)

=SUMIFS($E$5:$E$29,$D$5:$D$29,H5)

import pandas as pd

print(); print(df.columns)
print(); print(df.shape)
print(); print(df.head(5))
print(); print(df.tail(5))

print(); print("Print the dataset: ")
print(); print(df)
