         Name of sheet which will contain DataFrame.
-    na_rep : string, default ''
+    na_rep : str, default ''
         Missing data representation.
-    float_format : string, optional
+    float_format : str, optional
         Format string for floating point numbers. For example
         ``float_format="%%.2f"`` will format 0.1234 to 0.12.
-    columns : sequence or list of string, optional
+    columns : sequence or list of str, optional
         Columns to write.
-    header : boolean or list of string, default True

+    header : bool or list of str, default True
+        Write out the column names. If a list of string is given it is
         assumed to be aliases for the column names.
-    index : boolean, default True
+    index : bool, default True
         Write row names (index).
-    index_label : string or sequence, optional
+    index_label : str or sequence, optional
         Column label for index column(s) if desired. If not specified, and
         `header` and `index` are True, then the index names are used. A
         sequence should be given if the DataFrame uses MultiIndex.
-    startrow : integer, default 0
+    startrow : int, default 0
         Upper left cell row to dump data frame.
-    startcol : integer, default 0
+    startcol : int, default 0
         Upper left cell column to dump data frame.
-    engine : string, optional
+    engine : str, optional
         Write engine to use, 'openpyxl' or 'xlsxwriter'. You can also set this
         via the options ``io.excel.xlsx.writer``, ``io.excel.xls.writer``, and

-    merge_cells : boolean, default True
+    merge_cells : bool, default True
         Write MultiIndex and Hierarchical Rows as merged cells.
-    encoding : string, optional
+    encoding : str, optional

         other writers support unicode natively.
-    inf_rep : string, default 'inf'
+    inf_rep : str, default 'inf'
         Representation for infinity (there is no native representation for
         infinity in Excel).
-    verbose : boolean, default True
+    verbose : bool, default True
