Arithmetic operation

# create test dataframe
test_df = pd.DataFrame([
['A3', 0, -1, 0, 'si'],
['B1', 1, None, 0, 'no'],
['B3', 4, None, 0, 'no'],
['B3', 5, 1, 0, 'si'],
['A1', 4, 0, None, None],

, ['A3', 1, 2, 1, 'si'],
['C2', 4, 1, 1, 'no']],
columns=['A', 'B', 'C', 'D', 'E'],
index=[f'R{i}' for i in range(7)]
)
test_df


A B C D E

R0 A3 0 -1.0 0.0 si

R1 B1 1 NaN 0.0 no

R2 B3 4 NaN 0.0 no

R3 B3 5 1.0 0.0 si

R4 A1 4 0.0 NaN None

R5 A3 1 2.0 1.0 si

R6 C2 4 1.0 1.0 no



#add 10 to column D
test_df['D'] + 10

R0 10.0
R1 10.0
R2 10.0
R3 10.0
R4 NaN
R5 11.0
R6 11.0
Name: D, dtype: float64


# subtracting a value from column D
test_df['D'] - 10
test_df['D'].sub(10)

R0 -10.0
R1 -10.0
R2 -10.0
R3 -10.0
R4 NaN
R5 -9.0
R6 -9.0
Name: D, dtype: float64


#the above operations will not update the dataframe
