What are emojis, and why are they popular?

Emojis are small pictorial representations used to express emotions, ideas, or concepts in digital communication. These became popular in the late 1990s in Japan and have since gained immense popularity worldwide. Emojis provide a visual context to our messages, making them more engaging and expressive. Emojis have become a crucial aspect of our daily conversations, thanks to the emergence of social media and instant messaging platforms.

The popularity of emojis can be attributed to their ability to convey emotions quickly and effectively. In a world where virtual communication lacks non-verbal cues like facial expressions and body language, emojis fill that gap by adding a layer of emotion to our written words. From simple smileys to elaborate illustrations, emojis cover many feelings and ideas, making them universally appealing and relatable.

Using emojis in Python

Python offers several libraries and tools to work with emojis effortlessly. One such library is the emoji library, which provides a wide range of functions to handle emojis in your Python code. We must install and import the emoji library to use emojis in Python.

Installing and importing emoji library in Python

To install the emoji library, please open your terminal or command prompt and enter the following command:

pip install emoji

Output:

Once the installation is complete, we can import the emoji library into our Python script using the following line of code:

import emoji

With the emoji library successfully imported, we can now leverage its functions to work with emojis in Python.

Python Emoji Implementation

The emoji library in Python provides basic functions to perform common emoji operations. Let’s explore some essential emoji functions and understand how to use them in our code.

1. Getting the emoji representation of a Unicode

Using the emoji.emojize() function, we can convert a Unicode representation of an emoji into its corresponding emoji character. This function takes the Unicode as a parameter and returns the emoji representation. Here’s an example:

print(emoji.emojize(':thumbs_up:'))

Output:

2. Getting the Unicode representation of an emoji

Conversely, we can use the emoji.demojize() function to convert an emoji into its Unicode representation. This function takes the emoji character as a parameter and returns its Unicode. Let’s see an example:

print(emoji.demojize(''))

Output:

3. Checking if a string contains an emoji

The emoji library provides a useful function called emoji.emoji_count() to check if a string contains any emojis. This function returns the number of emojis found in the given string. Here’s how you can use it:

emoji.emoji_count('I love Python! ❤️')

Output:

Emoji Functions in Python

Two main functions are used in the emoji module: emojis and demojize.

The emojis function is used to get or print the emoji with the help of text or description of any emoji. For example, if we want to print the smiling face emoji, we can print it using the simple text “smiling face”

The demojize function is opposite to the emojis function, which is used to get an emoji’s description or tag. For example, if we have a smiling face emoji and want to get the tag from the same, we can use the demojize function in which we can pass the emoji, and it will return the name or description of the same.

Emojis Function

Now, let us try to implement the emojis function using Python code.

Example #1

Let us print the emojis with the grinning faces.

print("Emoji with grinning faces: ")
print(emoji.emojize(":grinning_squinting_face:"))
print(emoji.emojize(":grinning_face_with_smiling_eyes:"))
print(emoji.emojize(":grinning_face_with_sweat:"))

Output:

Let us try to print some more emojis using the emojize function.

Example #2

print(emoji.emojize(":upside-down_face:"))
print(emoji.emojize(":zany_face:"))
print(emoji.emojize(":shushing_face:"))

Output:

Demojize Function

We know that the demojize function returns the title or name of the emoji that we have passed as input to the function.

Let us try to demojize some of the emojis using Python code.

Example #1

Code:

message = "I love pizza! ❤️"
print(emoji.demojize(message)

Output:

Example #2

Code:

message = ""
print(emoji.demojize(message)

Output:

List of Emoji Unicode

	U+1F61C	Face with Stuck-Out Tongue and Winking Eye

This is just a small sample of the vast array of emojis available. Refer to the official Unicode website for a comprehensive list of emojis and their corresponding Unicode representations.

Advanced Emoji Functions and Customization Options

The emoji library in Python provides advanced functions and customization options to enhance our emoji experience. Let’s explore some of these features:

Emoji Skin Tone Modification

Emojis that depict human characters often come with different skin tone options. The emoji library allows us to modify the skin tone of these emojis using the emojize() function. Here’s an example:

emoji_text = emoji.emojize(":thumbs_up::skin-tone-2:")
print(emoji_text)

Output:

In this example, the skin-tone-2 modifier is applied to the “thumbs up” emoji, resulting in a medium skin tone.

Emoji Variation Selectors

Some emojis have multiple variations, such as gender-specific or style-specific options. The emoji library provides a way to select these variations using variation selectors. Here’s an example:

emoji_text = emoji.emojize(":man_gesturing_ok_type_1_2:")
print(emoji_text)

Output:

In this example, the variation selector type_1_2 displays the male version of the “person gesturing OK” emoji with a light skin tone.

Emoji Composition

Emojis can be composed by combining multiple emojis. The emoji library allows us to achieve this composition using the emojize() function. Here’s an example:

emoji_text = emoji.emojize(":woman::speech_balloon: Hello!")
print(emoji_text)

In this example, the “woman” emoji and the “speech balloon” emoji are combined to create a composition.

Output:

Repeating emojis

The emoji.emojize() function allows us to repeat an emoji multiple times. By passing the use_aliases=True parameter, we can use the emoji’s CLDR short name instead of its Unicode representation. Here’s an example:

print(emoji.emojize(':star:') * 5)

Output:

Removing emojis

If we want to remove emojis from a string, we can use the emoji.demojize() function. The input is processed, and any emojis are substituted with their corresponding Unicode representations. Here’s an example:

print(emoji.demojize('I ❤️ Python!'))

Output:
