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. |
