我是 python 的初學者，我正在嘗試創建一個自動備份我的文件的程序。我正在使用 shutil 制作檔案和 apscheduller 來安排備份。我想按日期命名我的備份文件，所以我使用 datetime 來獲取當前日期和時間。我在 StartUp 文件夾中有腳本，以便它在啟動時運行。這是我的代碼：now = datetime.now()date = now.strftime("%Y-%m-%d_%H-%M-%S")backup_dir = r'path/to/backups/folder/' + date + 'docs_backup'root_dir = r'C:/Users/user/'base_dir = r'documents'#This is to make the backup when the computer starts.shutil.make_archive( backup_dir, 'zip', root_dir, base_dir)@sched.scheduled_job('interval', hours=1)def zip_method(): #Make the backup archive every one hour shutil.make_archive( backup_dir, 'zip', root_dir, base_dir) print(date) print("I did a backup!")sched.start()這里的問題是日期變量被聲明一次，所以每個每小時的備份都會有一個過時的名稱。每次創建新存檔時，有什么辦法可以為日期變量分配一個新值嗎？

將文件生成名稱制作成一個函數，以便您可以隨時隨地調用它，如下所示。
ROOT_DIR = r'C:/Users/user/'
BASE_DIR = r'documents'
BACKUP_DIR = r'path/to/backups/folder/'
BACKUP_SUFFIX = 'docs_backup'
def make_backup_path():
now = datetime.now()
date = now.strftime("%Y-%m-%d_%H-%M-%S")
backup_path = BACKUP_DIR + date + BACKUP_SUFFIX
return backup_path
@sched.scheduled_job('interval', hours=1)
def zip_method():
#Make the backup archive every one hour
shutil.make_archive(
make_backup_path(),
'zip',
ROOT_DIR,
BASE_DIR)
print(date)
print("I did a backup!")
#This is to make the backup when the computer starts.
shutil.make_archive(
make_backup_path(),
'zip',
ROOT_DIR,
BASE_DIR)
sched.start()

考慮查找本地和全球范圍。如果將創建日期的代碼部分放在函數中，它會在每次調用時創建一個新日期。
#This is to make the backup when the computer starts.
shutil.make_archive(
backup_dir,
'zip',
root_dir,
base_dir)
@sched.scheduled_job('interval', hours=1)
def zip_method():
# Establish the key variables
now = datetime.now()
date = now.strftime("%Y-%m-%d_%H-%M-%S")
backup_dir = r'path/to/backups/folder/' + date + 'docs_backup'
root_dir = r'C:/Users/user/'
base_dir = r'documents'
#Make the backup archive every one hour
shutil.make_archive(
backup_dir,
'zip',
root_dir,
base_dir)
print(date)
print("I did a backup!")
sched.start()
