With this code, it is possible to export every data frame in a new worksheet iterating the data frames list:
def save_xls(list_dfs, xls_path):
writer = ExcelWriter(xls_path)
for n, df in enumerate(list_dfs):
df.to_excel(writer,'sheet_dati%s' % n)
But its possible to export two or more data frames in a single worksheet?
