Python循环打印

Question

我有一本这样的字典:

questions ={
'1.Who is Satoshi Nakamoto' : {'answers':{'right_answer':'Pseudonym','wrong_answer':['Bill Gate', 'Elon Musk', 'Warren Buffet']}},
'2.Who is richest' : {'answers':{'right_answer':'Pseudonym','wrong_answer':['Bill Gate', 'Elon Musk', 'Warren Buffet']}}
}

根据字典，我想打印问题和选项值。

这是我使用的代码:

for question in q:
print(question)
answers =([questions[question]['answers']['right_answer']] +questions[question]['answers']['wrong_answer'])
for answer in answers:
print(answer)

生成如下结果:

1.Who is Satoshi Nakamoto
Pseudonym
Bill Gate
Elon Musk
Warren Buffet
2.Who is richer
Pseudonym
Bill Gate
Elon Musk
Warren Buffet

但是我想打印带有项目头A, B, C, D等的选项，像这样:

1.Who is Satoshi Nakamoto
A.Pseudonym
B.Bill Gate
C.Elon Musk
D.Warren Buffet
2.Who is richer
A.Pseudonym
B.Bill Gate
C.Elon Musk
D.Warren Buffet

也许有人能帮我这个忙。非常感谢!

Answer 1

您想使用string库的ascii大写字母和zip()来枚举您的答案:

import string
answers = ['Pseudonym', 'Bill Gate', 'Elon Musk', 'Warren Buffet']
for bullet, answer in zip(string.ascii_uppercase, answers):
print(f"{bullet}. {answer}")

zip()将获取一定数量的列表(或其他集合)并将每个集合的第一个元素分组，然后是第二个，然后是第三个，依此类推。所以，zip([1,2,3], ['a','b','c'])会得到[(1, 'a'), (2, 'b'), (3, 'c')]。然后，for循环解包每个元组，并使它们可用于print语句的f-string。

这会产生以下结果:

>>> answers = ['Pseudonym', 'Bill Gate', 'Elon Musk', 'Warren Buffet']
>>> for bullet, answer in zip(string.ascii_uppercase, answers):
...     print(f"{bullet}. {answer}")
...
A. Pseudonym
B. Bill Gate
C. Elon Musk
D. Warren Buffet

Answer 2

我重新设计了questions的结构，因为我觉得它不好。制作questions列表允许我们对问题进行洗牌，这样它们就不会总是以相同的顺序出现。我把答案也打乱了，这样正确的答案就不会总是在第一个位置。

import random
import string
questions = [
{'question': 'Who is Satoshi Nakamoto',
'right_answer': 'Pseudonym',
'wrong_answers': ['Bill Gate', 'Elon Musk', 'Warren Buffet']},
{'question': 'Who is richest',
'right_answer': 'Pseudonym',
'wrong_answers': ['Bill Gates', 'Elon Musk', 'Warren Buffet']}]
random.shuffle(questions)
for i, entry in enumerate(questions, start=1):
all_answers = entry['wrong_answers'] + [entry['right_answer']]
random.shuffle(all_answers)
print(f'{i}. {entry["question"]}')
for letter, answer in zip(string.ascii_uppercase, all_answers):
print(f'  {letter}. {answer}')

可能的结果:

1. Who is richest
A. Pseudonym
B. Warren Buffet
C. Bill Gates
D. Elon Musk
2. Who is Satoshi Nakamoto
A. Elon Musk
B. Pseudonym
C. Warren Buffet
D. Bill Gate
