What Is Read Mode and How to Use It in Your Mi Smartphone?

What is reader mode?

Reader mode lets you view pages so that only text and accompanying images or videos display. Other page elements (banners, interactive elements, social network buttons, etc.) are hidden.

Tip. You can free up some more space for text by removing the upper browser panel from the screen. To do this, switch to the full-screen mode by pressing F11 . To exit the full-screen mode, press F11 again.

What is the readline() method in Python?

This method is going to read one line from the file and return that.

In this example, we have a text file with these two sentences:

If we use the readline() method, it will only print the first sentence of the file.

This method also takes in the optional size parameter. We can modify the example to add the number 7 to only read and print out This is:

How to Use Read Mode

  1. Launch a program such as Word and open a document with plenty of text so you can see how this alternative view handles a longer document. Note that not all Microsoft Office programs feature Read Mode or Reading Layout. 
  2. Click View > Read Mode in Office 2013 or later versions, or View > Full Screen Reading Layout in previous versions.
  3. While in this alternative mode, look for additional features. For example, in Word, you can find Tools in the upper left of the screen, such as Search with Bing (this allows you to search the web for anything you've highlighted within the document). Another example is the Find tool, which you are likely familiar with from the normal mode of Office programs. While not all editing features are available in this mode, these select tools can come in very handy. 
  4. To get out of Read Mode or Full-Screen Reading, just click View > Edit Document in Microsoft Word. In earlier versions, you can try clicking Close in the upper right of the user interface.

Which is better dark or light mode

Answered By: Gavin Brooks Date: created: Jan 18 2022

“Dark mode successfully cuts glare and reduces blue light, both of which help your eyes. However, dark mode isn’t for everyone, and in some cases, it can actually cause more vision problems than solutions.” Whether you should read in light or dark mode may depend on the time of day.

Why is night mode yellow

Answered By: Alfred Parker Date: created: Jun 05 2021

And, according to the study, the yellow tint that your phone’s night mode is using might actually be worse. The reason? Yellow light more closely imitates daylight, while blue light is similar to what we naturally experience as the sun goes down.

How is it different from e-readers?

To understand this better, let’s take an example of Amazon Kindle. While both the display mimic paper-like appearance, the e-paper display reflects light just like paper. It lacks a backlight, and hence it requires an external light source in order for you to read anything. 

On the other hand, the OnePlus 5 has a emissive (with a backlight) display. So, it just adjusts the screen’s colour to greyscale and eliminates blue light. It is quite similar to how Apple uses its True Tone feature on the iPad Pro.

Writing Files in Python

Before we can write to a file in Python, it must first be opened in a different file opening mode. We can do this by supplying the open() method with a special argument.

In Python, write to file using the open() method. You’ll need to pass both a filename and a special character that tells Python we intend to write to the file.

Add the following code to write.py. We’ll tell Python to look for a file named “sample.txt” and overwrite its contents with a new message.

Passing ‘w’ to the open() method tells Python to open the file in write mode. In this mode, any data already in the file is lost when the new data is written.

If the file doesn’t exist, Python will create a new file. In this case, a new file named “sample.txt” will be created when the program runs.

Run the program using the Command Prompt:

Python can also write multiple lines to a file. The easiest way to do this is with the writelines() method.

We can also write multiple lines to a file using special characters:

Using string concatenation makes it possible for Python to save text data in a variety of ways.

However, if we wanted to avoid overwriting the data in a file, and instead append it or change it, we’d have to open the file using another file opening mode.

Opening Other File Types

The open() method can read and write many different file types. We’ve seen how to open binary files and text files. Python can also open images, allowing you to view and edit their pixel data.

Before Python can open an image file, the Pillow library (Python Imaging Library) must be installed. It’s easiest to install this module using pip. 

With Pillow installed, Python can open image files and read their contents.

The Pillow library includes powerful tools for editing images. This has made it one of the most popular Python libraries.

Conclusion

If you want to read a text file in Python, you first have to open it.

If the text file and your current file are in the same directory (“folder”), then you can just reference the file name in the open() function.

If your text file is in a different directory, then you will need to reference the correct path name for the text file.

The open() function takes in the optional mode parameter. The default mode is the read mode.

If you want to check if a file can be read, then you can use the readable() method. This will return a True or False.

The read() method is going to read all of the content of the file as one string.

Once you are done reading a file, it is important that you close it. If you forget to close your file, then that can cause issues.

One way to ensure that your file is closed is to use the with keyword.

The readline() method is going to read one line from the file and return that.

The readlines() method will read and return a list of all of the lines in the file.

An alternative to these different read methods would be to use a for loop.
