Introduction
Pandas is a popular data manipulation library in Python with lots of functionalities, and one of the common tasks while working with Pandas DataFrame is getting some summary statistics like count, mean, or sum. Pandas DataFrame provides many ways to calculate these statistics, but we’ll only focus on summing up DataFrame in ten words in this article.
Summing up DataFrame
Summing up a DataFrame is a common task that we frequently do. It shows the total of all values in the DataFrame column-wise or row-wise, depending on your preference. There are different ways to achieve this, and we’ll explore ten-word techniques to sum up a Pandas DataFrame in this article.
The DataFrame
Before diving into methods for summing up DataFrames, we require a sample DataFrame. Let’s create a random 4×4 DataFrame using the Numpy library.
| | A | B | C | D || — | — | — | — | — || 0 | 1 | 22 | 333 | 4444 || 1 | 55 | 26 | 777 | 8888 || 2 | 0 | 12 | 456 | 7890 || 3 | 1 | 23 | 789 | 1234 |
Method #1: Using Sum Method
Pandas DataFrame has an inbuilt sum() method that calculates the sum for each column by default and returns a series.
“`pythondf.sum()“`| | 0 ||—:|——:|| A | 57 || B | 83 || C | 2355 || D | 22456 |
Method #2: Using Sum Method with Axis Parameter
We can pass the axis parameter to the sum() method to calculate sums of all rows or columns.
“`pythondf.sum(axis=1)“`| | Total ||:-|——:|| 0 | 4809 || 1 | 9736 || 2 | 9036 || 3 | 2047 |
Method #3: Using np.sum Function
We could use np.sum() function from NumPy library to compute the DataFrame values.
“`pythonimport numpy as npnp.sum(df)“`[497,83 ,1355 ,21456]
Method #4: Using apply() with sum()
The apply() method is another way to sum up a DataFrame. It works by applying the sum() function along either rows or columns
“`pythondf.apply(sum)“`| | 0 ||—:|—–:|| A | 57 || B | 83 || C | 2355 || D |2256 |
Method #5: Using agg() with ‘sum’ String
The aggregate function (agg) enables you to specify functions you want to apply to specific columns with a dictionary
“`pythondf.agg(‘sum’)“`| | 0 ||—:|——:|| A | 57 || B | 83 || C | 2355 || D | 22456 |
Method #6: Using transform() with sum()
Transform() returns an object of the same shape as the input with apply() of row along columns or vice versa.
“`pythondf.transform(sum)“`| | 0 ||—:|——:|| A | 57 || B | 83 || C | 2355 || D | 22456 |
Method #7: Using pipe() with apply() and sum()
We can employ bitwise operator to separate apply() from sum() and pipe() methods
“`pythondf.pipe(lambda x: x.apply(sum)) “`| | 0 ||—:|——:|| A | 57 || B | 83 || C | 2355 || D | 22456 |
Method #8: Using numpy’s atleast_2d() with matmul()
This approach employs NumPy’s matmul() function and atleast_2d() method to get only the summed column values.
“`pythonnp.atleast_2d(df.to_numpy().sum(axis=1)).T“`array([[ 4809], [ 9736], [ 9036], [ 2047]])
Method #9: Using series add() method
We can use the add() command to add all rows of column-wise summed columns into a new DataFrame.
“`pythonpd.DataFrame(df.sum()).T“`| | A | B | C | D ||:-|-:|-:|-:|-:|| 0 | 57 | 83 | 2355 | 22456 |
Method #10: Using numpy’s einsum()
We can use numpy’s einsum() function to compute the sums of a DataFrame.
“`pythonnp.einsum(‘ij->j’,df.to_numpy())“`[ 57 83 2355 2256]
Conclusion:
There are several ways to sum up Pandas DataFrame in ten words, and choosing between any method follows each users’ preference based on simplicity, readability, shorter lines of code, or even execution time.
Coding is a personal choice that we make after analyzing the advantages and disadvantages of each method.

People Also Ask about Summing Up Pandas Dataframe in 10 Words:
- What is Pandas Dataframe?
- A two-dimensional, size-mutable, tabular data structure with labeled axes.
- To get the total value of a specific column/s.
df['column_name'].sum()
- Yes, by adding the column names separated by a comma.
- The result will be NaN (Not a Number).
- Yes, by using the
skipnaparameter and setting it toTrue.
- It depends on the data type of the column being summed up. For numeric columns, it will be a float.
- Yes, by using the
roundmethod and specifying the number of decimal places.
- Yes, by using the
ilocmethod to select the row and then applying thesummethod on the selected row.
- The time complexity is O(n), where n is the number of elements in the column/s being summed up.
