Question

从电子表格导入数据时遇到问题。我正在尝试创建包含所有数据的列表。但是只有最后一行添加到列表中。

from openpyxl import load_workbook

path = "excel.xlsx"
l_data = load_workbook(path)
sheet = l_data.active
c_row = sheet.max_row
c_column = sheet.max_column
out_data=[]
dict={}
for a in range(1, c_row + 1):
    for b in range(1, c_column + 1):
        ob = sheet.cell(row=a, column=b)
        dict[b] = ob.value
    out_data.append(dict)

我需要这样的输出数据： [{1：“ row1_call1”，2：“ row1_call2”}，{1：“ row2_call1”，2：“ row2_call2”}]

尝试一个：

<?php

namespace App\Security;

use App\Entity\User;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\Exception\CustomUserMessageAuthenticationException;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
use Symfony\Component\Security\Core\Exception\InvalidCsrfTokenException;
use Symfony\Component\Security\Core\Security;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Core\User\UserProviderInterface;
use Symfony\Component\Security\Csrf\CsrfToken;
use Symfony\Component\Security\Csrf\CsrfTokenManagerInterface;
use Symfony\Component\Security\Guard\Authenticator\AbstractFormLoginAuthenticator;
use Symfony\Component\Security\Http\Util\TargetPathTrait;

class LoginAuthFormAuthenticator extends AbstractFormLoginAuthenticator
{
use TargetPathTrait;

private $entityManager;
private $urlGenerator;
private $csrfTokenManager;
private $passwordEncoder;

public function __construct(EntityManagerInterface $entityManager, UrlGeneratorInterface $urlGenerator, CsrfTokenManagerInterface $csrfTokenManager, UserPasswordEncoderInterface $passwordEncoder)
{
    $this->entityManager = $entityManager;
    $this->urlGenerator = $urlGenerator;
    $this->csrfTokenManager = $csrfTokenManager;
    $this->passwordEncoder = $passwordEncoder;
}

public function supports(Request $request)
{
    return 'app_login' === $request->attributes->get('_route')
        && $request->isMethod('POST');
}

public function getCredentials(Request $request)
{
    $credentials = [
        'email' => $request->request->get('email'),
        'password' => $request->request->get('password'),
        'csrf_token' => $request->request->get('_csrf_token'),
    ];
    $request->getSession()->set(
        Security::LAST_USERNAME,
        $credentials['email']
    );

    return $credentials;
}

public function getUser($credentials, UserProviderInterface $userProvider)
{
    $token = new CsrfToken('authenticate', $credentials['csrf_token']);
    if (!$this->csrfTokenManager->isTokenValid($token)) {
        throw new InvalidCsrfTokenException();
    }

    $user = $this->entityManager->getRepository(User::class)->findOneBy(['email' => $credentials['email']]);

    if (!$user) {
        // fail authentication with a custom error
        throw new CustomUserMessageAuthenticationException('Email could not be found.');
    }

    return $user;
}

public function checkCredentials($credentials, UserInterface $user)
{
    return $this->passwordEncoder->isPasswordValid($user, $credentials['password']);
}

public function onAuthenticationSuccess(Request $request, TokenInterface $token, $providerKey)
{
    if ($targetPath = $this->getTargetPath($request->getSession(), $providerKey)) {
        return new RedirectResponse($targetPath);
    }

    // For example : return new RedirectResponse($this->urlGenerator->generate('some_route'));
    return new RedirectResponse($this->urlGenerator->generate('page_forum'));
}

protected function getLoginUrl()
{
    return $this->urlGenerator->generate('app_login');
}
}

它更改字典值的类型。因此，仅此行更改自：

from openpyxl import load_workbook

path = "excel.xlsx"
l_data = load_workbook(path)
sheet = l_data.active
c_row = sheet.max_row
c_column = sheet.max_column
out_data=[]
dict={}
for a in range(1, c_row + 1):
    for b in range(1, c_column + 1):
        ob = sheet.cell(row=a, column=b)
        dict[b] = ob.value

    out_data.append(str(dict))

print(out_data)

收件人：

out_data.append(dict)

如果您想了解更多将字典追加到列表的信息，请检查该站点： python: Appending a dictionary to a list - I see a pointer like behavior

所以这也起作用：

out_data.append(str(dict))

如何通过openpyxl将整个工作表导入列表
