import xlrd
"""读取包含耽搁sheet的excel数据"""
workbook = xlrd.open_workbook("test.xlsx")  # 打开工作表
sheet0 = workbook.sheet_by_index(0)  # 获取工作簿
nrows = sheet0.nrows  # 获取总行数
for i in range(nrows):
    each_data = sheet0.row_values(i)

import xlrd
"""读取包含多个sheet的excel数据"""
workbook = xlrd.open_workbook("test.xlsx")  # 打开工作表
sheets = workbook.sheet_names()  # 获取所有工作簿
nums = excel_content.nsheets  # 获取sheet总个数
for i in range(nums):  # 遍历每个sheet
    sheet = excel_content.sheets()[i]  # 获取sheet[i]工作簿
    nrows = sheet.nrows  # 获取sheet[i]总行数
    for j in range(nrows):
        each_data = sheet.row_values(j)
        print(each_data)
