format() method to convert n to a string, which it then assigns to con_n. After the conversion, it confirms that con_n is a string by printing its type. Python's.format() function is a flexible way to format strings; it lets you dynamically insert variables into strings without ...
DataFrame.sparse.to_coo() should raise when the fill_value is not zero, since scipy.sparse only supports filling with 0. In [21]: df = pd.DataFrame({"A": pd.SparseArray([1, 1, 1, 2], fill_value=1)}) In [22]: df.sparse.to_coo().todense() Out[22]: matrix([[0], [0]...
