python django remove trailing newline from string

python django remove trailing newline from string

fileName = "some text\n"

fileName = fileName.rstrip("\n")
This will remove more than one newline if present.

If you only want to remove one newline, use

if fileName[-1:] == '\n':
      fileName = fileName[:-1]

fileName[:-1] is all of the string except for its last character, which is useful for
removing the trailing newline from a string.

* because list exclude the last element.

fileName[-1:] ------> get last element.
fileName[:-1] -------? get all elements except last one.
