Python - IF statement inside a for loop checking on a Json File-CodePudding

Here is my code, I'm trying to scan user's input against Json file that contains a wordlist of negative words in order to get the sum of negative words in a user's input.

Note: I take the user input in a list.

current Output: No output that relates to the code below is printed.

def SumOfNegWords(wordsInTweet):
    f = open ('wordList.json')
    wordList = json.load(f)
    NegAmount = 0
    
    for words in wordsInTweet: #for words in the input

        if  wordsInTweet in wordList['negative']: 
            NegAmount  = 1
            print("The Sum of Negative Words =", NegAmount)
        
        else: print("No negative words found")

CodePudding user response：

I think the line

if wordsInTweet in wordList['negative']:

is not what you want. I think you want to check every word separately inside the for loop. So write

if words in wordList['negative']:

In the future, please specify what does the current code do and what do you want it to do.

def SumOfNegWords(wordsInTweet):
    f = open ('wordList.json')
    wordList = json.load(f)
    NegAmount = 0
    
    for words in wordsInTweet: #for words in the input

        if  words in wordList['negative']: 
            NegAmount  = 1
            print("The Sum of Negative Words =", NegAmount)
        
        else: 
            print("No negative words found")

changed it a bit... words in if condition because that's what you're iterating over and indentation in else

CodePudding user response：

In your comment, you mention that you don't see output from either print statement. This makes me think that your input to the function "wordsInTweet" may be empty. I would suggest checking that that your list of words in the tweet is non-empty.

# Checks that the list is empty or None
if not wordsInTweet:
    print("Word list was empty")

If you are new to Python, I suggest looking into using a debugger in the future. Many IDEs will have a debugger built in, but you can also use a tool such as PDB. Debuggers allow you to step through your code and inspect the contents of your variables.

Also, I would suggest closing your file after you finish reading from it. For more information, see the docs: Reading and Writing File

with open('wordList.json') as f:
    wordList = json.load(f)
# Use wordList below
