• pd.ExcelFile(path).parse(sheet_name)
• pd.read_excel(path, sheet_name)

两者区别不大。前者可以通过.sheet_names函数获取包含所有sheet的列表
例：循环读取Excel中的sheet

>>> import pandas as pd
>>> xl = pd.ExcelFile(path)
>>> for sheet_name in xl.sheet_names:
>>>     df = pd.read_excel(xl, sheet_name)

>>> import pandas as pd
>>> xl = pd.ExcelFile(path)
>>> for sheet_name in xl.sheet_names:
>>>     df = xl.parse(sheet_name)
