File handling such as editing a file, opening a file, and reading a file tin can easily be carried out in Python. Reading a file in Python is a very common task that any user performs earlier making whatsoever changes to the file.

While reading the file, the new line character \n is used to denote the end of a file and the beginning of the next line. This tutorial volition demonstrate how to readline without a newline in Python.

Use the strip() and the rstrip() Methods to Read a Line Without a Newline in Python

The strip() method in Python helps in omitting the spaces that are present at the get-go (leading) and at the end (trailing). Besides white spaces, the strip() method besides includes the newline characters.

Hither's an instance you tin follow.

              with open("randomfile.txt", "r") equally file:     newline_break = ""     for readline in file:          line_strip = readline.strip()         newline_break += line_strip     print(newline_break)                          

The open() is used to open up the file. Note that the strip() method will get rid of the newline and the whitespaces at the beginning and the cease in the example in a higher place. To proceed the whitespaces and just omit the newline, the \n command is passed equally an argument or a parameter to the strip() method.

We can also use the rstrip() method because the strip() method omits both the leading and the trailing spaces. On the other manus, the rstrip() method but removes the trailing spaces or characters. This method is useful because the newline is present at the stop of every string. Nosotros can also mention the newline character past \n.

Follow this example below.

              with open up("randomfile.txt", "r") as file:     newline_break = ""     for readline in file:         line_strip = line.rstrip('\due north')         newline_break += line_strip     print(newline_break)                          

Utilize the splitlines and the dissever() Methods to Read a Line Without a Newline in Python

The splitlines() method in Python helps split a set of strings into a listing. Each string in the ready of the string is an chemical element of the listing. Thus, the splitlines() method splits the string wherever the newline is present.

              with open("randomfile.txt", "r") as file:     readline=file.read().splitlines()     print(readline)                          

Here, note that the point where the split takes identify is not mentioned. So, to mention the point where the split should accept identify manually, the split() method is used. This method performs the same task equally the splitlines() method, only information technology is a petty more than precise.

              with open("randomfile.txt", "r") as file:     readline=file.read().dissever("\northward")     print(readline)                          

Use slicing or the [] Operator to Read a Line Without a Newline in Python

The slicing operator in Python helps in accessing different parts of a sequence or cord separately. The slicing operator is defined as: string[starting index : ending index : step value].

Here's an case you can follow.

              with open up("randomfile.txt", "r") as file:     newline_break = ""     for readline in file:          line_strip = line[:-1]         newline_break += line_strip     impress(newline_break)                          

Note that in the instance to a higher place, we removed the last grapheme of every string with the assist of negative slicing, for case, [:-i].

Use the replace() Method to Read a Line Without a Newline in Python

As the proper noun suggests, the replace() is a congenital-in Python function used to return a string in which a substring with all its occurrences is replaced by some other substring.

Follow this example below.

              with open("randomfile.txt", "r") equally file:     newline_break = ""     for readline in file:         line_strip = line.supervene upon('\n', " ")         newline_break += line_strip     print(newline_break)
