We can reshape the Pandas series using ways like Transpose, reshape method, and melt function. A Pandas Series is a one-dimensional labeled array that can hold data of any type (integer, float, string, etc.). It is similar to a NumPy array but has an index associated with each element that can be used to access individual values. Reshaping refers to changing the shape or structure of the Pandas series for using the data in various ways. Algorithm The general algorithm to Reshape Pandas Series using different methods is as follows − Create a Pandas Series with some data. ... Read More
