String concatenation takes place on the next line in python

Python has a simple concatenation using the + operator. But I am observing something unusual.

I tried :

final_path = '/home/user/' + path + '/output'

Where path is a staring variable I want to concatenate.

print final_path

gives me:

/home/user/path
/output

Instead of /home/user/path/output

Why is going to the next line. Is the forward slash causing the issue. I tried using the escape character as well. but It does not work.

As victor said, your path variable has '\n' added at the end implicitly, so you can do such a trick to overcome the problem:

final_path = '/home/user/' + path.strip('\n') + '/output'

This happens when path is from another file for example a .txt where you are importing the data. I solved this by adding path.strip() which removes whitespaces before the str and after for the newline which is being generated. Just add .strip() to your variable.

maybe it depends on which string is contained in the variable path. If it ends with a carriage return ('\n'), this could explain why string variable final_path is printed on 2 lines.

From the looks of your code, it may be the variable path that is the problem. Check to see if path has a new line at the end. Escape characters start with a backslash \ and not a forward slash /.
