    line = line.replace("'", '')
    return line


with open("txt_file.txt", "r") as f_in:
    with open("out.txt", "w") as f_out:
        for line in f_in:
            line = transform_csv(line)
            f_out.write(line)
        f_out.close()
    f_in.close()


df = pd.read_csv('out.txt')
print(df)
