Save .txt file\’s lines to Python list
To save lines from a .txt file into a Python list, you utilize file handling methods effectively. Firstly, use `open()` with the file path and mode (‘r’ for read). Employ `readlines()` on the file object to retrieve all lines as list elements. This method reads each line including newline characters. Remember to close the file using `.close()` after reading to free up system resources and maintain good practice. Here’s a succinct example:
“`python
file_path = ‘example.txt’
with open(file_path, ‘r’) as file:
lines = file.readlines()
# ‘lines’ now contains each line from ‘example.txt’ as list elements
# Specify the path to your .txt file file_path = 'example.txt' # Open the file in read mode with open(file_path, 'r') as file: # Read all lines from the file into a list lines = file.readlines() # Print out the list of lines print(lines)
print(lines)
“`
This approach efficiently loads file contents into a list, preserving line breaks. For processing large files, consider reading line by line to manage memory usage better. Handle encoding explicitly with `open()` if necessary, ensuring compatibility with file content. Post-loading, `lines` can undergo further operations like filtering, searching, or modification in Python. Understanding these fundamentals empowers effective file handling, crucial in diverse programming scenarios involving text data manipulation.
