python实现对Excle表格的读写[Python基础]

python

1、使用xlrd模块读取数据

# 将excel表格内容导入到tables列表中

def import_excel(tab):

# 创建一个空列表,存储Excel的数据

tables = []

for rown in range(1, tab.nrows):

array = {"设备名称": "", "": "", "": "", "端口": "", "onuid": "", "认证密码": "", "load": "", "checkcode": ""}

array["设备名称"] = tab.cell_value(rown, 0)

array[""] = tab.cell_value(rown, 1)

array[""] = tab.cell_value(rown, 2)

array["端口"] = tab.cell_value(rown, 3)

array["onuid"] = tab.cell_value(rown, 4)

array["认证密码"] = tab.cell_value(rown, 9)

array["load"] = tab.cell_value(rown, 10)

array["checkcode"] = tab.cell_value(rown, 11)

tables.append(array)

return tables

# 导入需要读取Excel表格的路径

data = xlrd.open_workbook(r"G: est.xlsx")

table = data.sheets()[0]

for i in import_excel(table):

print(i)

2、使用xlwt和openpyxl进行写出

import pandas as pd

# 要事先下载好xlwt和openpyxl模块

def export_excel(tab):

# 将字典列表转换为DataFrame

pf = pd.DataFrame(list(tab))

# 指定字段顺序

order = ["设备名称", "", "", "端口", "onuid", "认证密码", "load", "checkcode"]

pf = pf[order]

# 将列名替换为中文

columns_map = {

"设备名称": "设备名称",

"": "",

"": "",

"端口": "端口",

"onuid": "onuid",

"认证密码": "认证密码",

"load": "load",

"checkcode": "checkcode"

}

pf.rename(columns=columns_map, inplace=True)

# 指定生成的Excel表格路径

file_path = pd.ExcelWriter("G: est1.xlsx")

# 替换空单元格

pf.fillna("", inplace=True)

# 输出

pf.to_excel(file_path, encoding="utf-8", index=False)

# 保存表格

file_path.save()

export_excel(tables)

 

3、使用xlsxwriter写出

def export_excel(data, fileName):  # xlsxwriter库储存数据到excel

workbook = xw.Workbook(fileName) # 创建工作簿

worksheet1 = workbook.add_worksheet("sheet1") # 创建子表

worksheet1.activate() # 激活表

title = ["设备名称", "", "", "端口", "onuid", "认证密码", "load", "checkcode"] # 设置表头

worksheet1.write_row("A1", title) # 从A1单元格开始写入表头

i = 2 # 从第二行开始写入数据

for j in range(len(data)):

insertData = [data[j]["设备名称"], data[j][""], data[j][""], data[j]["端口"], data[j]["onuid"], data[j]["认证密码"],

data[j]["load"], data[j]["checkcode"]]

row = "A" + str(i)

worksheet1.write_row(row, insertData)

i += 1

workbook.close() # 关闭表

export_excel(import_excel(table), "G: est1.xlsx")

网上有人说第三种写入速度快,本人亲测貌似没啥其区别,根据个人爱好写吧,但是xlsxwriter模块只能写入,无法修改貌似
