测试SD卡，直到失败的Python程序

Question

在这里急需一些帮助。

我一直在尽力想出一个简单的程序，该程序将承担以下任务：

不幸的是，我

是一个完全的编程新手，我做的最多的是BASIC程序，所以无论如何，这就是我迄今为止所拥有的一切：

import filecmp
import os
import shutil
count = 0
while (count < 2):
    if os.listdir ("E:\Test") ==[]:
        shutil.copy2("\UsersAndrewDesktopTest.txt","E:TestTest.txt")
        filecmp.cmp("\UsersAndrewDesktopTest.txt","E:TestTest.txt")
        count = count + 1
        break
else:
    shutil.rmtree("E:\Test")
    os.mkdir("E:\Test")

我在没有 While 循环的情况下运行了这个，但现在我完全困惑它只是无限循环。任何帮助都会很棒，谢谢！

对于那些感兴趣的人，这就是完成的程序的样子。

import filecmp
import os
import shutil
from datetime import datetime
#Imported all of the neccessary items for running the script
count = 0
read = 0
write = 0
copys = 0
fail = 0
delete = 0
data = shutil.disk_usage("E:\")
free = (data[2])
with open ("\Users\Andrew\Desktop\SD Card Testing\Test.txt","wb") as fout:
    fout.write(os.urandom(int(free)))
file = os.path.getsize("\Users\Andrew\Desktop\SD Card Testing\Test.txt")
start = datetime.now()
while (fail == 0):
#While the fail count is == 0 then do:
    if os.listdir ("E:\Test") ==[]:
        read = read + 1
#Check if the Dir is empty
        shutil.copy2("\Users\Andrew\Desktop\SD Card Testing\Test.txt","E:TestTest.txt")
        copys = copys + 1
        write = write + 1
        print ((file*copys)/(1048576*1024),"GB")
        if filecmp.cmp("\Users\Andrew\Desktop\SD Card Testing\Test.txt","E:TestTest.txt",shallow=False) == True:
            print(filecmp.cmp("\Users\Andrew\Desktop\SD Card Testing\Test.txt","E:TestTest.txt",shallow=False))
            read = read + 2
#If the result of the file check is true print
        else:
            fail = fail + 1
            print ("Fail:",fail)
#If the result of the file check is false fail and break
    else:
        shutil.rmtree("E:\Test")
        delete = delete + 1
        os.mkdir("E:\Test")
        write = write + 2
        print ("Deletes:",delete)
#If the folder is not empty then remove it and replace
    count = count + 1
    print (count)
    end = datetime.now()
    print ("Duration: {}".format(end-start))
#When the loop breaks print the number of read/writes
print ("Read:",read)
print ("Write:",write)

我相信人们将能够提供有关改进的建议，但我目前有两组SD卡测试，大约2.5 TB写入256 mB分区。
