How to Read a File Line-by-Line into a List?
You can read a file line-by-line into a list in Python using a loop to iterate over each line in the file and appending each line to a list. Here's how you can do it:
# Open the file for reading
with open('filename.txt', 'r') as file:
# Read lines from the file and store them in a list
lines = file.readlines()
# Print the list of lines
print(lines)
In this code:
'filename.txt'
is the name of the file you want to read. Replace it with the actual filename.'r'
specifies that the file should be opened in read mode.file.readlines()
reads all lines from the file and returns them as a list of strings, where each string represents one line of the file.- The list of lines is stored in the variable
lines
.
Now, the variable lines
contains a list where each element corresponds to a line from the file.
If you want to remove the newline characters ('\\n'
) from each line, you can use the rstrip()
method within a list comprehension like this:
# Open the file for reading
with open('filename.txt', 'r') as file:
# Read lines from the file, remove trailing newline characters, and store them in a list
lines = [line.rstrip('\\n') for line in file]
# Print the list of lines
print(lines)
This will give you a list where each line is stripped of any trailing newline characters.
