    for item in adv:

你有幾件事要發生在這里：

1. 您將響應保存到名為r的變量，而不是response ，因此未定義。
2. 您對price沒有做任何事情（不確定它是否只是留在您的示例代碼中）。
3. r.json()["data"]返回一個列表（一個數組），這意味着您需要選擇一個數字索引來訪問adv 。

例如

import requests

headers = {...

data = {...

r = requests.post(
    'https://p2p.binance.com/bapi/c2c/v2/friendly/c2c/adv/search', headers=headers, json=data)
print(r.text)

def main():
    val = r.json()["data"][0]["adv"] # notice im referring 'r' and im adding the [0] index before ["adv"]
    print(val)

if __name__ == '__main__':
    main()
