Question

我正在用Python编写一个脚本，该脚本提示您提出问题，并分析AskReddit的subreddit并给您答复。我的代码是：

import requests
import json
import random
 
#The main function that will grab a reply
def grab_reply(question):
    #Navigate to the Search Reddit Url
    r = requests.get('https://www.reddit.com/r/AskReddit/search.json?q=' + question + '&sort=relevance&t=all', headers = {'User-agent': 'Chrome'})
    
    answers = json.loads(r.text)    #Load the JSON file
    
    Children = answers["data"]["children"]
 
    ans_list= []
 
    for post in Children:
        if post["data"]["num_comments"] >= 5:   #Greater then 5 or equal  comments
            ans_list.append (post["data"]["url"])
        
    #If no results are found return "I have no idea"
    if len(ans_list) == 0:
        return "I have no idea"
    
    #Pick A Random Post
    comment_url=ans_list[random.randint(0,len(ans_list)-1)] + '.json?sort=top'  #Grab Random Comment Url and Append .json to end
 
    #Navigate to the Comments
    r = requests.get(comment_url, headers = {'User-agent': 'Chrome'})
    reply= json.loads(r.text)
    
    Children = reply[1]['data']['children']
    
    
    reply_list= []
 
    for post in Children:
        reply_list.append(post["data"]["body"]) #Add Comments to the List
    
    if len(reply_list) == 0:
        return "I have no clue"
        
    #Return a Random Comment
    return reply_list[random.randint(0,len(reply_list)-1)]
 
 
 
#Main Loop, Always ask for a question
while 1:
    input("Ask me anything: ")
    q=q.replace(" ", "+")   #Replace Spaces with + for URL encoding
    print(grab_reply(q))    #Grab and Print the Reply

在终端中运行脚本后，得到以下响应：

NameError: name 'q' is not defined

我已经设法从脚本中消除了大多数错误，但这使我发疯。帮助我，堆栈溢出。

Answer 1

这可能会帮助

while True:
    q = input("Ask me anything: ")

Answer 2

input("Ask me anything: ")

应为：

q = input("Ask me anything: ")

因此，您没有将输入的结果分配给任何变量。 q未定义。

Answer 3

q尚未定义。您应该在使用q之前定义它。

Python-NameError：名称“ q”未定义
