如何解决无法将文件保存到不存在的目录:'{parent}'&;错误呢?

Question

我想保存'df'到'dataset'文件。

这是我的代码代码文件名为'practice.py'

import pandas as pd
df = pd.DataFrame({
    "x1": [100000, 200000, 300000],
    "x2": [400000, 500000, 600000],
    "x3": [700000, 800000, 900000]},
     index=[2019, 2021, 2020]
)
df.index.name = 'year' # set the index name
df.to_csv('dataset/covid_dataset.csv', encoding='utf-8') # save to file

我想我设置的文件路径是正确的，但是我不知道错误在哪里。

这是我的文件结构:输入图片描述

错误信息如下:

(covid_project) C:self_projectcovid_project>C:/self_project/covid_project/Scripts/python.exe c:/self_project/covid_project/covid19_project/practice.py
Traceback (most recent call last):
  File "c:self_projectcovid_projectcovid19_projectpractice.py", line 13, in <module>
    df.to_csv('dataset/covid_dataset.csv', encoding='utf-8')
  File "C:self_projectcovid_projectlibsite-packagespandascoregeneric.py", line 3563, in to_csv
    return DataFrameRenderer(formatter).to_csv(
  File "C:self_projectcovid_projectlibsite-packagespandasioformatsformat.py", line 1180, in to_csv
    csv_formatter.save()
  File "C:self_projectcovid_projectlibsite-packagespandasioformatscsvs.py", line 241, in save
    with get_handle(
  File "C:self_projectcovid_projectlibsite-packagespandasiocommon.py", line 697, in get_handle
    check_parent_directory(str(handle))
  File "C:self_projectcovid_projectlibsite-packagespandasiocommon.py", line 571, in check_parent_directory
    raise OSError(fr"Cannot save file into a non-existent directory: '{parent}'")
OSError: Cannot save file into a non-existent directory: 'dataset'

下面是期望的结果:

• 我想将'df'保存为'covid_dataset.csv'文件名在'dataset'文件中。
