伙计们,我有一个数据,该数据在datadrame中我想将该数据转储到csv文件中,但我将所有数据都存储在一行中,但我没有如何实现它。请伙计们,它是请求不要使其重复,请在我做错的地方回答这是我的数据:
Asset_Id Asset Family Asset Name Location Asset Component
3 Nano Dial Assem NDA11 Zenoa Fusion Tank
1 Haptic Analy HAL3Technopolis Rotation Chamber Rotation Chamber
2 Hyperdome Insp HISP2 Zenoa Turbo Quantifier
4 Geometric Synth GeoSyn25 La Puente Ion Gas Diffuser
1 Haptic Analy HAL1Zenoa Tetris Measuring Unit Measurement
2 Hyperdome Insp HISP1 Technopolis Laser Column
3 Nano Dial Assem NDA14 Zenoa Wave Generator
4 Geometric Synth GeoSyn24 La Puente Progeometric Plane
“数据”包含我上面显示的值。这是我写的行,请编辑相同的代码
data = dataGen.compute(uploaded_file, recordCount)
#Output the generated data to the browser
proxy = io.StringIO()
writer = csv.writer(proxy)
writer.writerow(data.to_records(index=False))
# Creating the byteIO object from the StringIO Object
mem = io.BytesIO()
mem.write(proxy.getvalue().encode('utf-8'))
# mem.write(proxy.getvalue())
# seeking was necessary. Python 3.5.2, Flask 0.12.2
mem.seek(0)
return send_file(
mem,
as_attachment=True,
attachment_filename='test.csv',
mimetype='text/csv'
)
请帮助我如何将这些数据放入换行符,因为我将所有数据都放在一行中,或者建议进行任何编辑,请告诉我。...thnx

您似乎正在尝试将CSV文件写入内存,然后将send_file()
与内存版本一起使用。您应该可以使用df.to_csv()
直接以CSV格式写入数据,如下所示:
df = dataGen.compute(uploaded_file, recordCount)
mem = io.StringIO()
df.to_csv(mem, index=False, encoding='utf-8')
mem.seek(0)
return send_file(
mem,
as_attachment=True,
attachment_filename='test.csv',
mimetype='text/csv'
)
