如何从TXT文件读取文本并将逗号分隔内容拆分为单个元素存入Array

Hey there! Let's get this sorted for you. The main trick here is splitting the comma-separated text into individual elements once you read the file, instead of shoving the whole thing into a single array slot.

The core idea is: read the file → split the content by commas → clean up any extra whitespace around each item.

Here's a working code snippet:

# Safely read the content of your TXT file
with open('your_file.txt', 'r') as text_file:
    # Read the entire content and strip any leading/trailing newlines/spaces
    file_content = text_file.read().strip()

# Split the string by commas, then trim whitespace from each item
target_array = [item.strip() for item in file_content.split(',')]

# Check the result
print(target_array)
# Output: ['hello', 'school', 'tommy', 'house', 'homemaking']

Key Details: #

• file_content.split(','): This breaks the entire string into a list using commas as separators. Without cleaning, you'd get elements like " school" (with a leading space).
• item.strip(): This removes any leading/trailing spaces (or tabs/newlines) from each element, giving you clean, standalone words.
• The with open(...) syntax ensures the file is automatically closed after reading, which is good practice.

If you're working with JavaScript/Node.js, here's how you'd do it:

const fs = require('fs');

// Read the file as UTF-8 text
fs.readFile('your_file.txt', 'utf8', (error, data) => {
    if (error) throw error;
    // Trim extra whitespace, split by commas, then clean each item
    const targetArray = data.trim().split(',').map(item => item.trim());
    console.log(targetArray);
    // Output: ['hello', 'school', 'tommy', 'house', 'homemaking']
});

No matter which language you're using, the core logic stays the same: split the comma-separated string and clean up each element to get your desired array.
