To compute the sum of columns in Pandas, use the DataFrame's `sum(~)` method.

As an example, consider the following DataFrame:

``` df = pd.DataFrame({"A":[3,4],"B":[5,6]}, index=["a","b"])df A Ba 3 5b 4 6 ```

# Summing each column

To compute the sum of the values of each column:

``` df.sum() A 7B 11dtype: int64 ```

# Summing a specific column

To compute the sum of a specific column:

``` df["A"].sum() 7 ```
