I have a file path as a string and trying to remove the last '/' from the end.
my_file_path = '/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg/'
I've been trying it with regex but it just keeps removing all the '/'. Is there any easier way to just remove the last character without regex?
The easiest is
as @greggo pointed out
string="mystring";
string[:-1]
As you say, you don't need to use a regex for this. You can use rstrip.
my_file_path = my_file_path.rstrip('/')
If there is more than one / at the end, this will remove all of them, e.g. '/file.jpg//' -> '/file.jpg'. From your question, I assume that would be ok.
Answering the question: to remove the last character, just use:string = string[:-1].
If you want to remove the last '\' if there is one (or if there is more than one):
while string[-1]=='\\':
string = string[:-1]
If it's a path, then use the os.path functions:
dir = "dir1\\dir2\\file.jpg\\" #I'm using windows by the way
os.path.dirname(dir)
although I would 'add' a slash in the end to prevent missing the filename in case there's no slash at the end of the original string:
dir = "dir1\\dir2\\file.jpg"
os.path.dirname(dir + "\\")
When using abspath, (if the path isn't absolute I guess,) will add the current working directory to the path.
os.path.abspath(dir)
You could use String.rstrip.
result = string.rstrip('/')
For a path use os.path.abspath
import os
print os.path.abspath(my_file_path)
os.path.abspath() will also turn all forward slashes into backslashes on Windows platforms, so it may not always be the right solution.
abspath() is appropriate here.The simplest way is to use slice. If x is your string variable then x[:-1] will return the string variable without the last character. (BTW, x[-1] is the last character in the string variable) You are looking for
my_file_path = '/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg/'
my_file_path = my_file_path[:-1]
To remove the last character, just use a slice: my_file_path[:-1]. If you only want to remove a specific set of characters, use my_file_path.rstrip('/'). If you see the string as a file path, the operation is os.path.dirname. If the path is in fact a filename, I rather wonder where the extra slash came from in the first place.
No need to use expensive regex, if barely needed then try-
Use r'(/)(?=$)' pattern that is capture last / and replace with r'' i.e. blank character.
>>>re.sub(r'(/)(?=$)',r'','/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg/')
>>>'/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg'
stringvar[:-1]
