無法從 Jupyter Notebook 壓縮文件

Question

我嘗試壓縮文件，我使用了https://thispointer.com/python-how-to-create-a-zip-archive-from-multiple-files-or-directory/ 中的示例

with ZipFile('sample2.zip', 'w') as zipObj2:

   # Add multiple files to the zip
   zipObj2.write('sample_file.csv')

sample2.zip已創建，但它是空的。 當然， csv文件存在並且不為空。

• 我從 Jupyter Notebook 運行此代碼

編輯：我正在使用相對路徑 -

input_dir = "../data/example/" 
with zipfile.ZipFile(os.path.join(input_dir, 'f.zip'), 'a') as zipObj2: 
zipObj2.write(os.path.join(input_dir, 'f.tif'))

Answer 1

你試圖關閉 zip 文件來保存？

from zipfile import ZipFile

with ZipFile('sample2.zip', 'w') as zipObj2:
   zipObj2.write('sample_file.csv')
   zipObj2.close()

Answer 2

我對你的問題有點困惑，但如果我是對的，聽起來你是在嘗試將多個 CSV 文件放在一個壓縮文件中？ 如果是這樣，這就是您要尋找的：

#initiate files variable that contains the directory from which you wish to zip csv files
files=[f for f in os.listdir("./your_directory") if f.endswith('.csv')]

#initalize empty DataFrame 
all_data = pd.DataFrame()

#iterate through the files variable and concatenate them to all_data 
for file in files:
df = pd.read_csv('./your_directory' + file)
all_data = pd.concat([all_data, df])

然后調用您的新 DataFrame(all_data) 以驗證內容是否已傳輸。
