如何将文件中的“\n”文本作为换行符读取？

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

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadFile {
    public static void main(String[] args) {
        try (BufferedReader br = new BufferedReader(new FileReader("file.txt"))) {
            String line;
            while ((line = br.readLine()) != null) {
                line = line.replace("\\n", "\n");
                System.out.println(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

#include <iostream>
#include <fstream>
#include <string>

int main() {
    std::ifstream file("file.txt");
    if (file.is_open()) {
        std::string line;
        while (std::getline(file, line)) {
            size_t pos = line.find("\\n");
            while (pos != std::string::npos) {
                line.replace(pos, 2, "\n");
                pos = line.find("\\n", pos + 1);
            }
            std::cout << line << std::endl;
        }
        file.close();
    }
    return 0;
}
