通过 ZipFile.setpassword 命令使用变量

Question

我正在为我的班级编写一个脚本来打开受密码保护的 zip 文件。我有一个需要循环访问的密码列表。

我创建了一个脚本，当我在密码字段中手动输入密码时，它可以完美地执行该功能：ZipFile.setpassword(b'12345')

但我想要做的是使用变量 passwordattempt 来代替它，因为它循环遍历我列表的每个条目，就像这个 ZipFile.setpassword (b'passwordattempt') 但是当我这样做时，它永远不会起作用，而且似乎不起作用正在使用分配给变量的密码。

我可以通过使用 print(passattempt) 看到它正确地通过了我的列表

## Create a temp list of pass  ##
## words from the allpass.txt  ##
## file                        ##
#################################

#Create a temp Library
passwordlib = []

#Open temp allpassword file to put into temp list
with open('allpass.txt', 'r+') as f:
    for line in f:
        line = line.rstrip("\n")
        #print(line)
        passwordlib.append(line)
f.close()
#End of temp list creation


#Attempt to open zip file using the list of passwords in passwordlib[]
for line in passwordlib:
        passattempt = line.strip('\n')
        try:
          zip_ref = zipfile.ZipFile("Resources/ZippedFiles/testzip.zip", 'r')
          print (passattempt) #Print to confirm passwords are cycling through
          zip_ref.setpassword(b'passattempt')            
          zip_ref.extractall("Resources/ZippedFiles/testout/")
        except:
          pass #if password is incorrect, ignore Runtime error and move to next password      
        zip_ref.close()

是的，只需使用 encode 使用默认编码 (utf-8) 将 string 转换为 bytes。

import zipfile

with open('allpass.txt', 'r+') as f:
    passwordlib = f.readlines()

# Attempt to open zip file using the list of passwords in passwordlib[]
for line in passwordlib:
    passattempt = line.strip('\n')
    with zipfile.ZipFile("file.zip", 'r') as zf:
        print(passattempt)  # Print to confirm passwords are cycling through
        zf.setpassword(passattempt.encode())
        try:
            zf.extractall("Resources/ZippedFiles/testout/")
        except RuntimeError as e:
            if 'Bad password' not in str(e):
                raise
