DataFrame写入excel不同的sheet

直接上代码

初始化2个dataframe

df1 = pd.DataFrame(
    {
        'Name':['Jack', 'Kate', 'Jim', 'Steve'],
        'Gender':['M','F','M','M'],
        'Height':[17,15, 22, 18]
    }
)

df2 = pd.DataFrame(
    {
        'Name':['Jack', 'Kate', 'Jim', 'Steve'],
        'Gender':['M','F','M','M'],
        'Height':[17,15, 22, 18]
    }
)

准备输出写文件

write = pd.ExcelWriter('./output.xls')
df1.to_excel(excel_writer=write,sheet_name='df1_sheet', header=True, encoding="utf-8", index=False)
df2.to_excel(excel_writer=write,sheet_name='df2_sheet', columns=['Name', 'Gender'], header=True, encoding="utf-8", index=False)
write.save()
write.close()

执行结果
