检查单词在文本文件中出现的次数 (Python)

Question

我在 python 工作，试图找到在文本文件中找到输入的次数，但 output 始终显示文本文件的字母数，而不是单词在文件中出现的次数。 我不确定是什么导致它变成 output 字母计数。

def occurrenceChecker(query):
    wordInFile = 0 
    file = open("C:\Users\Noah\Desktop\1000words.txt") 
    documentText = file.read

    for query in documentText():
        wordInFile +=1
    
    if wordInFile == 0:
        print("Your argument occurred " + str(wordInFile) + " times, none.")
    if wordInFile >= 1 and wordInFile <= 5:
        print("Your argument occurred " + str(wordInFile) + " times, low.")
    if wordInFile >= 6 and wordInFile <= 10:
        print("Your argument occurred " + str(wordInFile) + " times, medium.")
    if wordInFile >=11:
        print("Your argument occurred " + str(wordInFile) + " times, high.")

Output：

Please enter an argument that you are searching for in the file: stuck
Your argument occurred 4875 times, high.
Your argument occurred 4875 times, high.

当您不想成为时，您正在呼叫 function，而当您想要成为时，您却没有呼叫 function。

for query in documentText(): for query in document_text:

将document_text = file.read更改为document_text = file.read()

def occurrenceChecker(query):
    word_in_file = 0 
    file = open("C:\Users\Noah\Desktop\1000words.txt") 
    document_text = file.read()

    for query in document_text:
        word_in_file +=1
    
    if word_in_file == 0:
        print("Your argument occurred " + str(word_in_file) + " times, none.")
    if 1 <= word_in_file <= 5:
        print("Your argument occurred " + str(word_in_file) + " times, low.")
    if 6 <= word_in_file <= 10:
        print("Your argument occurred " + str(word_in_file) + " times, medium.")
    if word_in_file>=11:
        print("Your argument occurred " + str(word_in_file) + " times, high.")

既然你已经有了，我们现在需要解决递增的问题。 代替

for query in document_text:
        word_in_file +=1

你实际上想做这样的事情：

occurrences = document_text.count(query)

然后当然你应该有一个main()并在所述main()中调用你的 function

def main():
    occurrenceChecker(input())

if __name__ == "__main__":
    main()
