Reading and writing files python

Question

I am trying to write three separate line in a text document based on input obtained from a dialogue window. I am sure this is a simple fix but I can't seem to write the three lines as separate lines. Would someone mind telling me what's wrong with this bit of code?

file = open('file.txt', 'wb') 
file.write('input1')
file.write('input2')
file.write('input3')

The inputs should be on different lines but instead they come out as:

input1input2input3

Instead of:

input1
input2
input3

Answer 1

Try this:

file = open('file.txt', 'wb')
file.write('input1\n')
file.write('input2\n')
file.write('input3\n')

You are appending the newline character '\\n' to advance to the next line.

If you use the with construct, it will automatically close the file for you:

with open('file.txt', 'wb') as file:
   file.write('input1\n')
   file.write('input2\n')
   file.write('input3\n')

Also, consider using a different variable name in place of file .

Answer 2

Your issue is that you haven't included newlines. Remember, Python is outputting like a typewriter--you don't tell it to go to a new line, it won't. The way to write a newline is \\n .

So,

file.write('\n'.join([input1, input2, input3]))

Would do it.
