我有一個腳本用於刪除比日期更早的圖像。如何將日期傳遞給Python中的腳本?
當我打電話來運行腳本時,是否可以將此日期作爲參數傳遞?
示例:此腳本delete_images.py
刪除舊的圖像不是日期(YYYY-MM-DD)
python delete_images.py 2010-12-31
腳本
import os, glob, time
root = '/home/master/files/' # one specific folder
#root = 'D:\\Vacation\\*' # or all the subfolders too
# expiration date in the format YYYY-MM-DD
### I have to pass the date from the script ###
xDate = '2010-12-31'
print '-'*50
for folder in glob.glob(root):
print folder
# here .jpg image files, but could be .txt files or whatever
for image in glob.glob(folder + '/*.jpg'):
# retrieves the stats for the current jpeg image file
# the tuple element at index 8 is the last-modified-date
stats = os.stat(image)
# put the two dates into matching format
lastmodDate = time.localtime(stats[8])
expDate = time.strptime(xDate, '%Y-%m-%d')
print image, time.strftime("%m/%d/%y", lastmodDate)
# check if image-last-modified-date is outdated
if expDate > lastmodDate:
try:
print 'Removing', image, time.strftime("(older than %m/%d/%y)", expDate)
os.remove(image) # commented out for testing
except OSError:
print 'Could not remove', image
