使用文件中的新行创建.TXT文件

Question

I am having issues when writing the file that within the txt file it does not place the second message to the next line. (When it prints to the screen it work as I intend it to work, but not in the file itself)

Note: My python version is 2.7.3

import os.path

home = os.path.expanduser("~")
check1 = os.path.exists(home + '/test.txt')

if check1 == False:
f = open(home + '/test.txt', 'a')
f.write("First line\n")
f.write("Second line")
f.close()

elif check1 == True:   
with open(home + '/test.txt') as f:
for line in f:
print line
f.close()

this is the basis for my code.

Thank you, Stuart

You used a Unix style line ending and then used a Windows specific text viewer to look at it. Notepad doesn't recognize a \\n as a newline character; it requires Windows style line endings: \\r\\n .

Go read up about line endings and how different OSes have different defaults. Increase your awareness and your knowledge of this issue. Then do this:

1. Put import os at the top.
2. f.write("First line" + os.linesep)
