Pandas DataFrame: squeeze() function

DataFrame - squeeze() function

The squeeze() function is used to squeeze 1 dimensional axis objects into scalars.

Series or DataFrames with a single element are squeezed to a scalar. DataFrames with a single column or a single row are squeezed to a Series. Otherwise the object is unchanged.

Syntax:

DataFrame.squeeze(self, axis=None)

Parameters:

Name	Description	Type/Default Value	Required / Optional
axis	A specific axis to squeeze. By default, all length-1 axes are squeezed.	{0 or ‘index’, 1 or ‘columns’, None} Default Value: None	Required

This method is most useful when you don’t know if your object is a Series or DataFrame, but you do know it has just a single column. In that case you can safely call squeeze to ensure you have a Series.

Returns: DataFrame, Series, or scalar
The projection after squeezing axis or all the axes.
