详解Python中xlsxwriter库的基本操作

import xlsxwriter

# 创建一个新的Excel文件
workbook = xlsxwriter.Workbook('example.xlsx')

# 添加一个名为"Sheet1"的工作表
worksheet = workbook.add_worksheet("Sheet1")

# 在工作表中写入数据
worksheet.write('A1', '姓名')
worksheet.write('B1', '年龄')
worksheet.write('A2', '张三')
worksheet.write('B2', 25)
worksheet.write('A3', '李四')
worksheet.write('B3', 30)

# 保存并关闭Excel文件
workbook.close()

import xlsxwriter

workbook = xlsxwriter.Workbook('example.xlsx')
worksheet = workbook.add_worksheet()

# 创建一个加粗的格式对象
bold_format = workbook.add_format({'bold': True})

# 在单元格中写入数据，并应用加粗格式
worksheet.write('A1', '标题', bold_format)
worksheet.write('A2', '数据1')
worksheet.write('B2', 100)

# 设置列宽和行高
worksheet.set_column('A:B', 15)
worksheet.set_row(0, 20)

workbook.close()

import xlsxwriter

workbook = xlsxwriter.Workbook('example.xlsx')
worksheet = workbook.add_worksheet()

# 写入一些数据
data = [10, 20, 30, 40, 50]
worksheet.write_column('A1', data)

# 创建一个柱状图对象
chart = workbook.add_chart({'type': 'column'})

# 添加数据系列到图表中
chart.add_series({
    'values': '=Sheet1!$A$1:$A$5',
    'name': '数据',
})

# 将图表插入工作表中
worksheet.insert_chart('C1', chart)

workbook.close()
