openpyxl

import openpyxl

wb = openpyxl.load_workbook('file.xlsx') 
res = len(wb.sheetnames)

pandas

import pandas as pd

xl = pd.ExcelFile('file.xlsx')
res = len(xl.sheet_names)

xlrd

import xlrd

# use on_demand=True to avoid loading worksheet data into memory
wb = xlrd.open_workbook('file.xlsx', on_demand=True)
res = len(wb.sheet_names())  # or wb.nsheets
