df = pd.read_excel("index300.xls", sheet_name="Directive Index")
df.dropna(axis=1, inplace=True, thresh=5)
print(df)

groupbyIndexName = df.groupby('指數中文全稱Index Chinese Name(Full)')
print(groupbyIndexName.count())
print(groupbyIndexName.mean())
print(groupbyIndexName.sum())
print(groupbyIndexName.std())
print(groupbyIndexName.describe())
print(groupbyIndexName.describe().transpose())
