How to calculate variance in Pandas
To calculate a variance in Pandas just use a var method which Pandas is offering to you.
import pandas as pd
my_df = pd.DataFrame({"my_column1": [9, 2, 3, 5],
"my_column2": [3, 7, 6, 4],
"my_column3": [4, 8, 8, 8]})
print(f'The variance of columns:\n{my_df.var()}')
The variance of columns: my_column1 my_column2 my_column3 0 9 3 4 1 11 10 12 2 14 16 20 3 19 20 28
For more details see the documentation of var function.
