如何打印“和”字。 列表中的字典

Question

所以我在列表中有一本字典。 並在該字典中列出。

travel_log =[
{
    "country": "Russia",
    "visits": 2,
    "cities": ["Moscow", "Saint Petersburg"]
},
]

我想打印出來：

你去過莫斯科和聖彼得堡。

如何？

Answer 1

這會起作用：

print(f"You have been to {travel_log[0]['cities'][0]} and {travel_log[0]['cities'][0]}")

Answer 2

你可以試試這個方法

print("You've been to" + " and ".join(travel_log[0]['cities']))

Answer 3

請試試這個：

for country in travel_log:
cities = ""
cities_size = len(country["cities"]) - 1
for idx, city in enumerate(country["cities"]):
    if idx > 0:
        if cities_size == idx:
            cities += " AND "
        else:
            cities += ", "

    cities += city
    
print("You've been to "+cities+" at "+country["country"])

Answer 4

有便利的inflect package。 您需要使用pip install inflect它

import inflect

travel_log =[
{
    "country": "Russia",
    "visits": 2,
    "cities": ["Moscow", "Saint Petersburg"]
},
]

p = inflect.engine()
for journey in travel_log:
    print(f"You have been to {p.join(journey['cities'])}") 

output

You have been to Moscow and Saint Petersburg

如果超過 2 個元素，它將是，例如：

You have been to Moscow, Volgograd, and Saint Petersburg

package 還提供更方便的功能 - 正確生成復數、單數名詞、序數、不定冠詞； 將數字轉換為單詞。
