pandas 2.2.1 支持 xlsxwriter 3.2.0。
以下是使用 pandas 和 xlsxwriter 的详细步骤:
安装 pandas 和 xlsxwriter
确保你已经安装了 pandas 和 xlsxwriter,你可以使用以下命令来安装它们:
pip install pandas==2.2.1 pip install xlsxwriter==3.2.0
导入所需的库
在 Python 脚本中,你需要导入 pandas 和 xlsxwriter 库:
import pandas as pd from openpyxl import Workbook
创建 Pandas DataFrame
接下来,你可以创建一个 Pandas DataFrame,并将其保存为一个 Excel 文件,这里我们使用一个简单的示例数据:
data = {'Name': ['John', 'Emma', 'Mike'], 'Age': [25, 28, 31], 'City': ['New York', 'London', 'Paris']} df = pd.DataFrame(data)
将 DataFrame 写入 Excel 文件
现在,我们可以使用 xlsxwriter 将 DataFrame 写入一个名为 "output.xlsx" 的 Excel 文件中:
创建一个工作簿对象 workbook = Workbook() worksheet = workbook.active 将 DataFrame 转换为字典格式并逐行写入工作表 for r in dataframe_to_rows(df, index=False, header=True): worksheet.append(r) 保存工作簿到文件 workbook.save("output.xlsx")
在上面的代码中,dataframe_to_rows
是一个辅助函数,用于将 DataFrame 转换为逐行的字典列表,你可以通过运行 pip install openpyxl
命令来安装 openpyxl,它包含了这个函数。
完整示例代码
下面是一个完整的示例代码,演示了如何使用 pandas 2.2.1 和 xlsxwriter 3.2.0,并将一个包含姓名、年龄和城市的 DataFrame 保存到一个名为 "output.xlsx" 的 Excel 文件中:
