How to Specify New Lines on Python, When Writing on Files

Writing string to a file on a new line every time

Use "\n":

file.write("My String\n")

See the Python manual for reference.

Write newline character explicitly in a file

Just replace the newline character with an escaped new line character

text = "where are you going?\nI am going to the Market?"
with open("output.txt",'w', encoding="utf-8") as output:
    output.write(text.replace('\n','\\n'))

How do I specify new lines in a string in order to write multiple lines to a file?

It depends on how correct you want to be. \n will usually do the job. If you really want to get it right, you look up the newline character in the os package. (It's actually called linesep.)

Note: when writing to files using the Python API, do not use the os.linesep. Just use \n; Python automatically translates that to the proper newline character for your platform.

I can't add a new line when writing a file in Python

I think what you want is appending to the file, instead of writing (truncating the file if it already exists):

    # ...

    else:
        taken.append(file_name)
        file = open('logs.txt', 'a+')  # 'a+' mode instead of 'w' mode
        file.write(file_name + '\n')
        file.close()
    # ...

How to write in new line in file in Python

You can just use f.write(str(word)+"\n") to do this. Here str is used to make sure we can add "\n".

If you're on Windows, it's better to use "\r\n" instead.

python file.write() does not create new line

Try adding \n at the end of the string

How to type on a new line?

if you want to format the output you can use \n wherever you need the output to go to a newline.

data = {'sku: ***'+sku0+'*** Size: ***'+size0+'*** Stock: ***'+stock0+'***\n'

if you want to format the code I would suggest using a variables holding each line and then use + to add all of them together

Correct way to write line to file?

This should be as simple as:

with open('somefile.txt', 'a') as the_file:
    the_file.write('Hello\n')

From The Documentation:

Do not use os.linesep as a line terminator when writing files opened in text mode (the default); use a single '\n' instead, on all platforms.

Some useful reading:

The with statement
open()
- 'a' is for append, or use
- 'w' to write with truncation
os (particularly os.linesep)
