count how many times the same word occurs in a txt file

Question

Hello I am struggling with this: I have a txt file that once open looks like this:

Jim, task1\n
Marc, task3\n
Tom, task4\n
Jim, task2\n
Jim, task6\n

And I want to check how many duplicate names there are. I am interested only in the first field (i.e person name).

I tried to look for an answer on this website, but I could not find anything that helped, as in my case I don't know which name is duplicate, since this file txt will be updated frequently.

As I am new to Python/programming is there a simple way to solve this without using any dictionaries or list comprehensions or without importing modules?

Thank you

same_word_count = 0
with open('tasks.txt','r') as file2:
content = file2.readlines()
for line in content:
    
    split_data = line.split(', ')
    user = split_data[0]
    word = user

    if word == user:
            same_word_count -= 1
print(same_word_count)

Why do you not want to use dictionaries or lists? Those are essential tools that you will need to use for most of your python programming experience.

You can do the following.

word = "Word" # word you want to count
count = 0
with open("temp.txt", 'r') as f:
    for line in f:
        words = line.split()
        for i in words:
            if(i==word):
                count=count+1
print("Occurrences of the word", word, ":", count)

Or you can get list of all words occurrences

# Open the file in read mode
text = open("sample.txt", "r")
  
# Create an empty dictionary
d = dict()
  
# Loop through each line of the file
for line in text:
    # Remove the leading spaces and newline character
    line = line.strip()
  
    # Convert the characters in line to
    # lowercase to avoid case mismatch
    line = line.lower()
  
    # Split the line into words
    words = line.split(" ")
                         
  
    # Iterate over each word in line
    for word in words:
        # Check if the word is already in dictionary
        if word in d:
            # Increment count of word by 1
            d[word] = d[word] + 1
        else:
            # Add the word to dictionary with count 1
            d[word] = 1
  
# Print the contents of dictionary
for key in list(d.keys()):
    print(key, ":", d[key])

Thank you for your help. Just a question: in my case I don't know what word I will look for. I just need to find any duplicates, fi there are. This text file will be updated frequently so it might be that a word has not duplicate anymore. Thank you — Markus Pe, Jan 03 '23 at 12:04
