CSV 循环遍历行

Question

像大多数人一样，我正在尝试学习 Python 以提升我的职业生涯等……作为其中的一部分，我们正在考虑在工作中部署 Cisco Meraki。由于我们将拥有大量网络，因此能够通过 API 部署来自 csv 文件的信息会非常棒。

我已经设法让下面的代码在一定程度上工作。它会成功运行，但只运行 CSV 的最后一行，而不是每一行，直到没有行为止。

CSV 包含大约 130 行子网、IP 地址和网络 ID

我很接近，但我似乎无法理解最后一点。

    # actionBatch-VlanUpdate.py

import requests
import csv

# Environment Variables
API_KEY = "xxxxxx"
org_id = xxxxx
url = f"https://api.meraki.com/api/v0/organizations/{org_id}/actionBatches"

with open('Subnets.csv', newline="\n") as csvfile:
    readCSV = csv.reader(csvfile, delimiter=',')
    for row in readCSV:
     net_id = row[3]
     V5NET = row[4]
     V5GW = row[5]
     V10NET = row[6]
     V10GW = row[7]
     V11NET = row[8]
     V11GW = row[9]



payload = {
    "confirmed": True,
    "synchronous": True,
    "actions": [
        {
            "resource": f"/networks/{net_id}/vlans",
            "operation": "create",
            "body": {
                "id": "5",
                "name": "Data",
                "applianceIp": f"{V5GW}",
                "subnet": f"{V5NET}/24",
            },
        },
        {
            "resource": f"/networks/{net_id}/vlans",
            "operation": "create",
            "body": {
                "id": 10,
                "name": "Voice",
                "applianceIp": f"{V10GW}",
                "subnet": f"{V10NET}/24",
            },
        },
        {
            "resource": f"/networks/{net_id}/vlans",
            "operation": "create",
            "body": {
                "id": 11,
                "name": "Property",
                "applianceIp": f"{V11GW}",
                "subnet": f"{V11NET}/24",
            },
        },
    ],
}

headers = {
    "X-Cisco-Meraki-API-Key": API_KEY,
    "Content-Type": "application/json",
}

response = requests.post(url, json=payload, headers=headers)
print(response.text)

根据反馈修改版本

Answer 1

在您的 for 循环中，您将覆盖之前每次迭代的结果，因此它将始终是文件中的最后一行。您可以使用 .append() 数组方法将每个循环的结果插入到各种数组的末尾。

编辑 - 看起来你在 for 循环之前声明了数组。如果你只想调用 requests 130 次，你只需要更改缩进，这样你的 requests 调用就在你的 for 循环中。

编辑 2 - 您也希望在 for 循环中获取 requests 调用。

    readCSV = csv.reader(csvfile, delimiter=',')
    for row in readCSV:
        net_id = row[3]
        V5NET = row[4]
        V5GW = row[5]
        V10NET = row[6]
        V10GW = row[7]
        V11NET = row[8]
        V11GW = row[9]
        payload = {
            "confirmed": True,
            "synchronous": True,
            "actions": [
                ...
            ],
        }

        headers = {
            "X-Cisco-Meraki-API-Key": API_KEY,
            "Content-Type": "application/json",
        }

        response = requests.post(url, json=payload, headers=headers)
        print(response.text)
