python + Excel数据读取（更新）

data.xlsx 数据如下:

import xlrd

#1.读取Excel数据# table = xlrd.open_workbook("data.xlsx","r")# print("获取excel的所有标签:",table.sheets())# for sheet in table.sheets():#     print(sheet)

#2.读取第一个标签 第二个标签 ....# table = xlrd.open_workbook("data.xlsx","r")# sheetname = table.sheet_by_name("Sheet1")# print("sheetname:",sheetname)# sheetname1 = table.sheet_by_index(0)# print("sheetname1:",sheetname1)

#3.读取excel数据指定的行数和列数 nrows 行数 ncols 列数# table = xlrd.open_workbook("data.xlsx","r")# sheet1 = table.sheet_by_index(0)# print("Sheet1下面有{}行数据".format(sheet1.nrows))# print("Sheet1下面有{}列数据".format(sheet1.ncols))

#4.获取指定的行数和列数 row_values 行数  col_values 列数# table = xlrd.open_workbook("data.xlsx","r")# sheet1 = table.sheet_by_index(0)# onesheetrow = sheet1.row_values(0)# print("第一行的数据:",onesheetrow) #第一行的数据: [‘用户名‘, ‘密码‘, ‘预期结果‘]# onesheetcol = sheet1.col_values(0)# print("第一列的数据:",onesheetcol)#第一列的数据: [‘用户名‘, 18797813131.0, 18797813121.0, 18797813122.0, 18797813123.0, 18797813124.0]

#5.获取指定行和指定列的数据 cell# table = xlrd.open_workbook("data.xlsx","r")# sheet1 = table.sheet_by_index(0)# row_col = sheet1.cell(0,0)# print("第一行和第一列的数据:",row_col)# row_col1 = sheet1.cell(2,1)# print("第二行和第一列的数据:",row_col1)

#6.获取excel的用户名和密码# table = xlrd.open_workbook("data.xlsx","r")# sheet1 = table.sheet_by_index(0)# rows = sheet1.nrows# for i in range(1,rows): # 1,2,3,4,5#     print("当前的用户名为:",sheet1.row_values(i)[0],#           "密码为:",sheet1.row_values(i)[1],#           "获取的登录信息为:",sheet1.row_values(i)[2])

#7.写一个方法,输入行数,返回该行的所有数据# def read_user(nrow=0):#     """读取用户名"""#     table = xlrd.open_workbook("data.xlsx","r")#     sheet1 = table.sheet_by_index(0)#     return sheet1.row_values(nrow)[0]## def read_passwd(nrow):#     """读取密码"""#     table = xlrd.open_workbook("data.xlsx", "r")#     sheet1 = table.sheet_by_index(0)#     return sheet1.row_values(nrow)[1]## # print(read_user(1),read_passwd(1))## row_number = int(input("请输入行数"))# print("第{}行的数据是:{}".format(row_number,read_user(row_number)))

#8.读取的数据存储在List的中def readExcels():    tables = xlrd.open_workbook("data.xlsx", "r")    sheet = tables.sheet_by_index(0)    nrow = [] #定义空列表    for row in range(1,sheet.nrows):        nrow.append(sheet.row_values(row,start_colx=0,end_colx=sheet.ncols))    return nrowprint(readExcels())
