Here is how to read a file line-by-line into a list in Python.

# Open the file in read mode
with open('file.txt', 'r') as file:
    # Read all the lines of the file into a list
    lines = file.readlines()

# Print the list of lines
print(lines) 

Copy & Run

To read a file line-by-line into a list in Python, you can use the readlines() method of the file object. 

Alternatively, you can also use a for loop to iterate over the lines of the file and append them to a list. Here is an example of how to do this:

# Open the file in read mode
with open('file.txt', 'r') as file:
    # Create an empty list to store the lines
    lines = []

    # Iterate over the lines of the file
    for line in file:
        # Remove the newline character at the end of the line
        line = line.strip()

        # Append the line to the list
        lines.append(line)

# Print the list of lines
print(lines)
