python - 如何使用嵌套字典遍历列表？

Question

所以我有一个包含嵌套字典的列表，我想做的是从字典中读取 View 的值并将它们放入乘法器。

video_ads=({'title': 'Healthy Living', 'company': 'Health Promotion 
Board','views': 15934},
{'title': 'Get a ride, anytime anywhere', 'company': 'Uber', 'views': 
923834},
{'title': 'Send money with GrabPay', 'company': 'Grab', 'views': 23466},
{'title': 'Ubereats now delivers nationwide', 'company': 'Uber', 'views': 
1337},
{'title': 'Get cabs now with UberFlash', 'company': 'Uber', 'views': 90234})

所以我想做的是将标题与由某个因素乘以的 View 结合起来，这就是我到目前为止所写的内容

def payment_for_views(x):
    for x in range(0,5):
        x = x+1

        if video_ads[x]['views'] >= 50000:
            payment = video_ads[x]['views']*0.55
        elif views <50000 and video_ads[x]['views'] >=10000:
            payment=video_ads[x]['views']*0.68
        else:
            payment = video_ads[x]['views']*0.82
    #print(x)
    print(video_ads[x]['title'] + ': $'+ str(payment))
    print(video_ads[x]['title'] + ': $'+ str(payment))
    print(video_ads[x]['title'] + ': $'+ str(payment))
    print(video_ads[x]['title'] + ': $'+ str(payment))
    print(video_ads[x]['title'] + ': $'+ str(payment))

但它似乎只打印一行，例如:

 Get cabs now with UberFlash: $49628.700000000004
 Get cabs now with UberFlash: $49628.700000000004
 Get cabs now with UberFlash: $49628.700000000004
 Get cabs now with UberFlash: $49628.700000000004
 Get cabs now with UberFlash: $49628.700000000004

这就是我得到的全部。我需要 5 行，所有这些都有不同的标题和不同的数量。帮助!!!并提前致谢!

video_ads=({'title': 'Healthy Living', 'company': 'Health Promotion Board','views': 15934},
           {'title': 'Get a ride, anytime anywhere', 'company': 'Uber', 'views': 923834},
           {'title': 'Send money with GrabPay', 'company': 'Grab', 'views': 23466},
           {'title': 'Ubereats now delivers nationwide', 'company': 'Uber', 'views': 1337},
           {'title': 'Get cabs now with UberFlash', 'company': 'Uber', 'views': 90234})

def payment_for_views(item):
    if item >= 50000:
        payment = item * 0.55
    elif item < 50000 and item >= 10000:
        payment = item * 0.68
    else:
        payment = item * 0.82
    return payment

[print(per_ad['title'], ': $' + str(payment_for_views(per_ad['views']))) for per_ad in video_ads]

输出:

Healthy Living : $10835.12

Get a ride, anytime anywhere : $508108.70000000007

Send money with GrabPay : $15956.880000000001

Ubereats now delivers nationwide : $1096.34

Get cabs now with UberFlash : $49628.700000000004
