Python循环，通过列表从请求中写入文件

Question

我正在尝试编写一个循环，通过请求从 url 获取 .json，然后将 .json 写入 .csv 文件。然后我一遍又一遍地需要它，直到我的名称列表（.txt 文件）完成（89 行）。我无法让它遍历列表，它只是选择我列表的底部名称然后退出。我需要它通过并基本上创建 89 个文件，并带有正确的 url。其他功能正常，但只执行一次。

我似乎找不到适合我的目的的循环。由于我是python的初学者，我希望我能在这里得到一些帮助并了解更多

我的代码

#Opens the file with pricelists

with open('prislistor.txt', 'r') as f:
    for i, line in enumerate(f):
        pricelists = (line.strip())

response = requests.get('https://api.example.com/3/prices/sublist/{}/'.format(pricelists), headers=headers)

#Formats it
parsed = json.loads(response.text)

listan=(json.dumps(parsed, indent=4, sort_keys=True))

#Converts and creates a .csv file.
data = parsed['Prices']

with open('listan-{}.csv'.format(pricelists), 'w') as outf:
    dw = csv.DictWriter(outf, data[0].keys())
    dw.writeheader()

    for row in data:
        dw.writerow(row)

print ("The file list-{}.csv is created!".format(pricelists))

Python 使用缩进（空格、制表符）来标记代码块，您需要将循环逻辑放在循环块内

#Opens the file with pricelists

with open('prislistor.txt', 'r') as f:
    for i, line in enumerate(f): # from here on, a looping code block start with 8 spaces
        pricelists = (line.strip())
        # Keeps the indents
        response = requests.get('https://api.example.com/3/prices/sublist/{}/'.format(pricelists), headers=headers)

        #Formats it
        parsed = json.loads(response.text)

        listan=(json.dumps(parsed, indent=4, sort_keys=True))

        #Converts and creates a .csv file.
        data = parsed['Prices']

        with open('listan-{}.csv'.format(pricelists), 'w') as outf:
            dw = csv.DictWriter(outf, data[0].keys())
            dw.writeheader()

            for row in data:
                dw.writerow(row)

        print ("The file list-{}.csv is created!".format(pricelists))

    # codes here is outside the loop but still INSIDE the 'with' block, so you can still access f here

# codes here leaves all blocks
