How to Read a Text File into a Single String Variable in Python?

Reading a Text File into a String Variable Without Newlines

Many scenarios require processing text files as a continuous string, without the presence of newlines that delineate individual lines. This article explores how to accomplish this task in programming.

One approach is to utilize the open() function with the 'r' mode to read the file contents. Subsequently, the read() method can extract the entire file contents. To strip the newlines, you can employ the replace() method to substitute all occurrences of 'n' (the newline character) with an empty string.

with open('data.txt', 'r') as file:
    data = file.read().replace('\n', '')

Alternatively, if you are certain that the text file contains a single line, you can utilize the rstrip() method to remove trailing whitespace characters, including the newline:

with open('data.txt', 'r') as file:
    data = file.read().rstrip()

By implementing these methods, you can efficiently read a text file into a single-line string, effectively eliminating the presence of newlines that might otherwise impede your data processing tasks.
