python - python脚本 - 调用函数的问题

问题描述

目前我正在开发一个项目，该项目是一个脚本，它从定义的列表中生成一个随机问题，并要求用户对这些问题进行加权，最后返回一个字典，显示每个问题的权重

问题是我不确定在哪里调用主函数，而且脚本返回一个空字典！

谁能帮我解决这个问题

import random

dict = {
    "easy":["q1", "q2", "q3"],
    "mid":['q4', 'q5', 'q6', 'q7'],
    "hard":['q8', 'q9', 'q10', 'q11', 'q12']
}



tamplate = []
def make_random_tamp():
    # print(random.choices(quistions))
    i = 0
    e = 0
    m = 0
    h = 0
    random_easy_q = ''
    random_mid_q = ''
    random_hard_q = ''
    while (i < 6):
        while(e < 2):
            random_easy_q = random.choices(dict["easy"])
            if random_easy_q not in tamplate:
                tamplate.append(random_easy_q)
                e+=1
                i+=1
            continue
        while(m < 2):
            random_mid_q = random.choices(dict["mid"])
            if random_mid_q not in tamplate:
                tamplate.append(random_mid_q)
                m+=1
                i+=1
            continue
        while(h < 2):
            random_hard_q = random.choices(dict["hard"])
            if random_hard_q not in tamplate:
                tamplate.append(random_hard_q)
                h+=1
                i+=1
            continue
    return tamplate



make_random_tamp()

w_quistion = {}

def wheights(tamplate, dict):
    for i in tamplate:
        j=0
        if tamplate[j] in dict["easy"]:
            w_quistion[input("please enter wheight from 1-5 to this quistion :")] = tamplate[j]
            j+=1
        elif tamplate[j] in dict["mid"]:
            w_quistion[input("please enter a wheight from 6-15 to this quistion :")] = tamplate[j]
            j+=1
        elif tamplate[j] in dict["hard"]:
            w_quistion[input("please enter a weight from 15-25 to this quistion :")] = tamplate[j]
            j+=1

    return w_quistion




print(wheights(tamplate, dict)) ```

解决方案

您的实施中有两个主要问题：

  1. 您定义tamplate为一个空列表，但函数的返回值make_random_tamp未分配给tamplate.
  2. 您的字典值是列表对象，因此您需要用于extend()在主列表中添加元素，否则它将是列表列表。
import random

def make_random_tamp():
    i = 0
    e = 0
    m = 0
    h = 0
    random_easy_q = ''
    random_mid_q = ''
    random_hard_q = ''
    tamplate = []
    while (i < 6):
        while(e < 2):
            random_easy_q = random.choices(dict_ob["easy"])
            if random_easy_q not in tamplate:
                tamplate.extend(random_easy_q)  # use extend instead of append
                e+=1
                i+=1
            continue
        while(m < 2):
            random_mid_q = random.choices(dict_ob["mid"])
            if random_mid_q not in tamplate:
                tamplate.extend(random_mid_q)
                m+=1
                i+=1
            continue
        while(h < 2):
            random_hard_q = random.choices(dict_ob["hard"])
            if random_hard_q not in tamplate:
                tamplate.extend(random_hard_q)
                h+=1
                i+=1
            continue

    return tamplate


def wheights(tamplate, dict_ob):
    w_quistion = {} # create local object here
    # other code here
    return w_quistion


tamplate = make_random_tamp()
print(wheights(tamplate, dict_ob))

除了上述问题，您应该避免使用dict对象名称等关键字，并且字典w_quistion可以在wheights()函数中声明为本地对象。

注意：为简洁起见，我删除了部分代码。
