DataFrame

Constructor

DataFrame([data, index, columns, dtype, copy])

Two-dimensional size-mutable, potentially heterogeneous tabular data structure with labeled axes (rows and columns).

 

Axes

• index: row labels
• columns: column labels

DataFrame.as_matrix([columns])	Convert the frame to its Numpy-array representation.
DataFrame.dtypes	Return the dtypes in this object.
DataFrame.ftypes	Return the ftypes (indication of sparse/dense and dtype) in this object.
DataFrame.get_dtype_counts()	Return the counts of dtypes in this object.
DataFrame.get_ftype_counts()	Return the counts of ftypes in this object.
DataFrame.select_dtypes([include, exclude])	Return a subset of a DataFrame including/excluding columns based on their dtype.
DataFrame.values	Numpy representation of NDFrame
DataFrame.axes	Return a list with the row axis labels and column axis labels as the only members.
DataFrame.ndim	Number of axes / array dimensions
DataFrame.size	number of elements in the NDFrame
DataFrame.shape	Return a tuple representing the dimensionality of the DataFrame.
DataFrame.memory_usage([index, deep])	Memory usage of DataFrame columns.
