Are Python Series mutable?

Series is value-mutable but size-immutable. DataFrame is a 2-dimensional (2D) table of data with index labels and column labels. Each column in a DataFrame is a Series . DataFrame is value-mutable and size-mutable (mutable in terms of the column number).

Is a series object is value-mutable?

Series Objects are value-mutable but size-immutable objects.

Is DataFrame size mutable?

All pandas data structures are value-mutable (the values they contain can be altered) but not always size-mutable. The length of a Series cannot be changed, but, for example, columns can be inserted into a DataFrame.
