How do i read a text file without an n in python?
You can read the whole file and split lines using Show
Or you can strip the newline by hand:
Note: this last solution only works if the file ends with a newline, otherwise the last line will lose a character. This assumption is true in most cases (especially for files created by text editors, which often do add an ending newline anyway). If you want to avoid this you can add a newline at the end of file:
Or a simpler alternative is to
Or even, although pretty unreadable:
Which exploits the fact that the return value of The
Since Note: for symmetry to How to Read a File Without Newlines in Python? A newline is used to mark the end of a line and the beginning of a new one, and in this article we are going to look at how to read a file in Python without these newline breaks. To begin with we are going to create a simple newline.txt:Hello(return) my(return) name(return) is(return) Rikesh.(return)
Background: Opening and Reading a FileNow that we have our basic file= open("newline.txt", "r") file.read() # 'Hello\nmy\nname\nis\nRikesh.\n' Using this method we can see that the newline is being read by Python and represented by the A much cleaner way of opening files in Python is
using the with open("newline.txt", "r") as file: line = file.read() print(file) Output: Hello my name is Rikesh. Whilst it may appear different from the previous example, by using our print statement we have just asked Python to implement the newline code. Effectively, our output looks like this: Hello\nmy\n name\n is\n Rikesh.\n Method 1: Splitting with splitlines() and split(‘\n’)
with open("newline.txt", "r") as file: line=file.read().splitlines() print(line) # ['Hello', 'my', 'name', 'is', 'Rikesh.'] The with open("newline.txt", "r") as file: line=file.read().split("\n") print(line) # ['Hello', 'my', 'name', 'is', 'Rikesh.'] Whilst both of these methods remove the newlines, by default each of our original lines of text has been returned as a separate item in a list. This, obviously, has limited functionality unless our initial file contained individual string items we wanted to keep separate in the first place — for example, a list of numbers. In our example, with a pure text-only file the output is less useful. Method 2: Stripping with strip() and rstrip()In Python the newline_space.txt: Hello (return) my (return) name (return) is(return) Rikesh. (return) Although the actual text is the same we have added some whitespaces before and after our text entries. The final thing to note with this method is that, as it works through our file on a string by string basis, we need to iterate over our file to ensure
with open("newline_space.txt", "r") as file: newline_breaks="" for line in file: stripped_line = line.strip() newline_breaks += stripped_line print(newline_breaks) # HellomynameisRikesh. As we can see, the with open("newline_space.txt", "r") as file: newline_breaks="" for line in file: stripped_line = line.strip(‘\n’) newline_breaks += stripped_line print(newline_breaks) # Hello my name is Rikesh. Whilst the with open("newline_space.txt", "r") as file: newline_breaks="" for line in file: stripped_line = line.rstrip(‘\n’) newline_breaks += stripped_line print(newline_breaks) Hello my name is Rikesh. Method 3: SlicingAnother way to remove the newline is by slicing, but it should be noted this should be used with extreme caution as it is less targeted than our other methods. With slicing we can ask Python to remove the last character of each string, through
negative slicing with open("newline.txt", "r") as file: newline_breaks="" for line in file: stripped_line = line[:-1] newline_breaks += stripped_line print(newline_breaks) # HellomynameisRikesh. However, please bear in mind that slicing is indiscriminate – it will not care what the last character is and we can not specify this. So, although it works when our original file is consistent and has all the newline breaks in the right places, what happens if that’s not the case? Let’s change our original file to make it less consistent, and more like the kind of real-world file we are likely to be dealing with: newline_slice.txt:Hello(return) my(return) name(return) is(return) Rikesh In this file, the full stop and return at the end of the last line have been removed, so the last character for that script is with open("newline_slice.txt", "r") as file: newline_breaks="" for line in file: stripped_line = line[:-1] newline_breaks += stripped_line print(newline_breaks) # HellomynameisRikes The output has sliced (chopped-off) the last character of my name. We therefore need to be sure of the integrity and formatting of our original file before we can use this method, otherwise we risk losing data. Method 4: ReplaceThe final method we are going to look at is with open("newline.txt", "r") as file: newline_breaks = "" for line in file: stripped_line = line.replace('\n', " ") newline_breaks += stripped_line print(newline_breaks) # Hello my name is Rikesh. Whilst this has given us the most cleanly formatted of all our examples, this is only because of the formatting of our original file. However, SummaryWe have seen a number of different methods for reading a file without newlines. Each one is effective in it’s own way and does the job of removing our newlines, so there is no right answer. The correct method will depend on the original file we are working from, both in terms of content (plain text, integers) and formatting (whitespaces, consistency). If you need to keep items separated, splitting might be the best option. If you need to concatenate the output replacing or stripping could be the answer. Opening and reading the file first, without any formatting to assess the file content and structure, would be the most important step in deciding which method most suits your needs. How do you remove n from a text file in Python?Use the strip() Function to Remove a Newline Character From the String in Python. The strip() function is used to remove both trailing and leading newlines from the string that it is being operated on. It also removes the whitespaces on both sides of the string.
How do you stop reading N in Python?Linked. 342. Getting rid of \n when using .readlines(). Remove the newline character in a list read from a file.. to read line from file without getting "\n" appended at the end.. Read file into list and strip newlines.. file.readlines leaving blank lines.. Reading a txt file into a list without newlines in python.. How do I read a text file in Python?To read a text file in Python, you follow these steps: First, open a text file for reading by using the open() function. Second, read text from the text file using the file read() , readline() , or readlines() method of the file object. Third, close the file using the file close() method.
Does readline () take in the \n at the end of line?Properties of Python file readline() method
The readline() method only reads one complete line at a time. It adds a newline ( "\n" ) at the end of every line. It returns a string value if the file is opened in normal read “r” mode. This method returns the binary object if the file is opened in the binary mode “b”.
