Nov 6, 2017 · To get the number of rows of a DataFrame or get the length of a Series, use the len function. An integer will be returned. To get the total number of elements in the DataFrame or Series, use the size attribute. For DataFrames, this is the product of the number of rows and the number of columns.

Nov 28, 2021 · In this article, we will discuss how to get the size of the Pandas Dataframe using Python. Method 1 : Using df.size. This will return the size of dataframe i.e. rows*columns. Syntax: dataframe.size. where, dataframe is the input dataframe. Example: Python code to create a student dataframe and display size

Apr 11, 2013 · len(df.columns) ## Here: # df is your data.frame # df.columns returns a string. It contains column's titles of the df. # Then, "len()" gets the length of it. Getting the number of rows: len(df.index) # It's similar.

6 days ago · df.size is used to return the total number of elements in a DataFrame or Series. If we’re working with a DataFrame it gives the product of rows and columns or if we’re working with a Series it just returns the number of elements (rows). Return : Size of dataframe/series.

pandas.DataFrame.size# property DataFrame. size [source] # Return an int representing the number of elements in this object. Return the number of rows if Series. Otherwise return the number of rows times number of columns if DataFrame.

The size property returns the number of elements in the DataFrame. The number of elements is the number of rows * the number of columns. In our example the DataFrame has 169 rows and 4 columns: 169 * 4 = 676

pandas.DataFrame# class pandas. DataFrame (data = None, index = None, columns = None, dtype = None, copy = None) [source] # Two-dimensional, size-mutable, potentially heterogeneous tabular data. Data structure also contains labeled axes (rows and columns). Arithmetic operations align on both row and column labels.

May 9, 2023 · This article explains how to get the number of rows, columns, and total elements (size) in pandas.DataFrame and pandas.Series.

Nov 28, 2024 · Creating DataFrame from dict of ndarray/lists: To create DataFrame from dict of narray/list, all the narray must be of same length. If index is passed then the length index should be equal to the length of arrays. If no index is passed, then by default, index will be range (n) where n is the array length. Output:

The size of a dataframe in pandas is the total number of objects (or cells) in the dataframe whereas the length of a dataframe is the total number of rows in the dataframe. You can use the built-in len() function in Python or the first value in the tuple returned by the shape property to get a dataframe’s length.
