python xlsxwriter

这篇文章主要介绍了关于python调用xlsxwriter创建xlsx的方法,有着一定的参考价值,现在分享给大家,有需要的朋友可以参考一下

通过pip安装xlsxwriter

pip install xlsxwriter
Copy after login
Copy after login

下面进行基本的操作演示:

1. 首先创建一个excel的文档

workbook = xlsxwriter.Workbook(dir)
Copy after login
Copy after login

2. 在文档中创建表

table_name = 'sheet1'
worksheet = workbook.add_worksheet(table_name) # 创建一个表名为‘sheet1'的表,并返回这个表对象
Copy after login
Copy after login

3. 创建表后,就可以在表格上面进行写入操作

worksheet.write_column('A1', 5) # 在A1单元格写入数字5
Copy after login
Copy after login

有时候,我们想修改输入内容的格式,例如设置字体颜色加粗,斜体,日期格式等,这时候,就可以通过使用xlsxwriter提供的格式类。

具体可见:http://xlsxwriter.readthedocs.io/format.html

下面以写入一个粗体的红色的日期类为例

import datetime
# 需要先把字符串格式化成日期
date_time = datetime.datetime.strptime('2017-1-25', '%Y-%m-%d')
# 定义一个格式类,粗体的红色的日期
date_format = workbook.add_format({'bold': True, 'font_color': 'red', 'num_format': 'yyyy-mm-dd'})
# 写入该格式类
worksheet.write_column('A2', date_time, date_format)
Copy after login
Copy after login


4. xlsxwriter支持很多图表格式的插入

具体可以参见:http://xlsxwriter.readthedocs.io/chart.html

这里摘抄一段图标类型的介绍:

excel定义的图分两级类别描述,第一级分别有九大类,如下所示

area: 面积图
bar: 转置直方图
column: 柱状图
line: 直线图
pie: 饼状图
doughnut: 环形图
scatter: 散点图
stock: 股票趋势图
radar: 雷达图

第二级则是描述是否有连线,是否有平滑曲线等细节调整。

 percent_stacked
column

scatter
 straight_with_markers
 straight
 smooth_with_markers

下面举例绘制一个散点图。

chart1 = workbook.add_chart({'type': 'scatter', 'subtype': 'straight'})
chart1.set_title({'name': '图1'})
chart1.add_series({
 'name': '系列1',
 # 集合范围
 'categories': '=sheet1!$A$1:$A$89',
 # 数值范围
 'values': '=sheet1!$B$1:$B$89'),
 # 是否连线
 'line': {'none': True},
 # 默认图格式
 'marker': {'type': 'automatic'},
})
# 设置y轴的范围
chart1.set_y_axis({'max': 1.1, 'min': 0})
chart1.set_size({'x_scale': 2, 'y_scale': 2})
# 把图例插入到表中的C2位置,并且设置横轴偏移量为25,纵轴偏移量为10
worksheet.insert_chart('C2', chart1, {'x_offset': 25, 'y_offset': 10})
Copy after login
Copy after login
