Question

我编写了以下程序，列出了不同文件夹中的最后文件创建时间：

import os, os.path, time

path = raw_input("BackUp root Path: ")
folders = os.listdir(path)
report_list = dict()

for x in folders:
    if os.path.isfile(path+"\\"+x):
        folders.remove(x)

print
print
print "Last file creation time:"
for folder in folders:
    for root,dirs,files in os.walk(path+"\\"+folder):
        for filename in files:
            if not report_list.has_key(folder):
                report_list[folder]=time.strftime('%Y/%m/%d', time.gmtime(os.path.getctime(root+"\\"+filename)))
            this_file_date = time.strftime('%Y/%m/%d', time.gmtime(os.path.getctime(root+"\\"+filename)))
            if int(report_list[folder].translate(None,"/"))< int(this_file_date.translate(None,"/")):
                report_list[folder]= this_file_date

for folder in folders:
    if report_list.has_key(folder):
        print  "    {:<25}--->{:>15}".format(folder,report_list[folder])
    else:
        print  "    {:<25}--->{:>15}".format(folder,"Empty!")
print
print


my_filter = raw_input("Do you want to filter output? (y/n): ")
if my_filter== 'y':
    date=raw_input("Enter date(Example --> 2010/10/23): ")
    print
    print
    print "Filtered output:"
    for folder in folders:
        if report_list.has_key(folder):
            if int(report_list[folder].translate(None,"/"))< int(date.translate(None,"/")):
                print  "    {:<25}--->{:>15}".format(folder,report_list[folder])
        else:
            print  "    {:<25}--->{:>15}".format(folder,"Empty!")

嗯，它有时会返回错误。例如，当我将地址//10.0.0.100/shares作为输入时，我面临以下错误，表明文件不存在！

虽然文件确实在那里：

（无论如何，搜索它，意味着当我创建列表时它就在那里！）

Answer 1

问题显然是因为文件名使用波斯语字符。将您的文件名更改为英文字符，它可以工作。而且，而不是

    x+"\\"+y

使用：

    os.path.join(x,y)

我用 Python 3.5 重写程序，现在它工作正常，没有任何错误：

import os, os.path, time

path = input("BackUp root Path: ")
folders = os.listdir(path)
report_list = dict()

for x in folders:
    if os.path.isfile(path+"\\"+x):
        folders.remove(x)

print ()
print ()
print ("Last file creation time:")
for folder in folders:
    for root,dirs,files in os.walk(path+"\\"+folder):
        for filename in files:
            if not folder in report_list:
                report_list[folder]=time.strftime('%Y/%m/%d', time.gmtime(os.path.getctime(root+"\\"+filename)))
            this_file_date = time.strftime('%Y/%m/%d', time.gmtime(os.path.getctime(root+"\\"+filename)))
            if int(report_list[folder].replace("/",""))< int(this_file_date.replace("/","")):
                report_list[folder]= this_file_date

    if folder in report_list:
        print("    {:<25}{:>15}".format(folder,report_list[folder]))
    else:
        print("    {:<25}{:>15}".format(folder,"Empty!"))

print
print


my_filter = input("Do you want to filter output? (y/n): ")
if my_filter== 'y':
    date=input("Enter date(Example --> 2010/10/23): ")
    print ()
    print ()
    print ("Filtered output:")
    for folder in folders:
        if folder in report_list:
            if int(report_list[folder].replace("/",""))< int(date.replace("/","")):
                print("    {:<25}{:>15}".format(folder,report_list[folder]))
        else:
            print("    {:<25}{:>15}".format(folder,"Empty!"))

Python存在时找不到文件
