Pycss

Pycss is a module that will help you to colorise your output in the terminal. This module also allows you to do a variety of logic opertations on various color formats, such as RGB and Hex color codes.

How does it work?

Pycss uses ANSI color codes. Read about the ANSI codes.

Note: This module may not work wih certain terminals as they may not support ANSI color codes.

Installation

To install the pycss module, use the following command:

pip install pycss

Import pycss with the following code snippet:

# Not pycss
import css

Documentation

Before the documentation starts, you should be familiar with css colors.

Inbuilt foreground colors

You can access the css colors by refferring to the color variables css.COLORNAME.

Note: The css colors are 3-bit and 4-bit colors. If your terminal does not support 3-bit and 4-bit colors, it will not be able to understand them.

Variable	Color
GREY	Grey
RED	Red
GREEN	Green
YELLOW	Yellow
BLUE	Blue
MAGENTA	Magenta
CYAN	Cyan
WHITE	White
NOCOLOR	Transparent
C_BLACK	Bright Black
C_RED	Bright Red
C_YELLOW	Bright Yellow
C_GREEN	Bright Green
C_BLUE	Bright Blue
C_MAGENTA	Bright Magenta
C_CYAN	Bright Cyan
C_WHITE	Bright White

Inbuilt background colors

You can access the css background colors by refferring to the background color variables css.BGCOLORNAME.

Note: The css background colors are 3-bit and 4-bit colors. If your terminal does not support 3-bit and 4-bit colors, it will not be able to understand them. css.BACKROUND_COLOR

Variable	Color
BGGREY	Grey
BGRED	Red
BGGREEN	Green
BGYELLOW	Yellow
BGBLUE	Blue
BGMAGENTA	Magenta

C_BGWHITE	Bright White

Using external foreground colors

If you want to use a specific foreground color with your text output, you can use the pycss inbiult functions to convert hex or RGB color codes to usable ANSI color codes: hex2color() or rgb2color().

Note: The ANSI color code that will be returned by the above functions is 24-bit. If your terminal does not support 24-bit colors, it will not be able to understand them.

import css

# Hex code
hex_code = "#FFF"
ansi_color_code = css.hex2color(hex_code)

# RGB color
red, green, blue = 255, 255, 255
ansi_color_code = css.rgb2color(red, green, blue)

# The ansi_color_code can also be used with the color() function.

Using external background colors

If you want to use a specific background color with your text output, you can use the pycss inbiult functions to convert hex or RGB color codes to usable ANSI color codes: hex2bgcolor() or rgb2bgcolor().

Note: The ANSI color code that will be returned by the above functions is 24-bit. If your terminal does not support 24-bit colors, it will not be able to understand them.

import css

# Hex code
hex_code = "#FFF"
ansi_color_code = css.hex2bgcolor(hex_code)

# RGB color
red, green, blue = 255, 255, 255
ansi_color_code = css.rgb2bgcolor(red, green, blue)

# The ansi_color_code can also be used with the bgcolor() function. 
# Scroll down to learn more.

Coloring the text

To color text, you use the color() function.

Parameters

1. text - The text you want colored.
2. color - Pass in the color you desire. It can either be an inbuilt foreground color or an external foreground color.

Returns:
Returns a string with your colored text.

import css

# Inbuilt color (3-bit and 4-bit color)
colored_text = css.color("Hello World!", css.RED)
print(colored_text)

# External color (24-bit true color)
hex_color = "#d62828"
ansi_color_code = css.hex2color(hex_color)
colored_text = css.color("Hello World!", ansi_color_code)
print(colored_text)

Applying background

To apply background to text, you use the bgcolor() function.

Parameters

1. text - The text you want to be colored
2. background_color - Pass in the background color you desire. It can either be an inbuilt background color or an external background color.

Note: You don't use normal strings for background colors eg: "red".USE pycss's background color!

Returns:
Returns a string with your background-applied text.

import css

# Inbuilt color (3-bit and 4-bit color)
colored_text = css.bgcolor("Hello World!", css.BGRED)
print(colored_text)

# External color (24-bit true color)
hex_color = "#d62828"
ansi_color_code = css.hex2color(hex_color)
colored_text = css.bgcolor("Hello World!", ansi_color_code)
print(colored_text)

Making text bold

To make text bold, you use the bold() function.

Parameter

1. text - The text you want bold.

Returns: It returns a string containing the bolded text.

import css

bolded_text = css.bold("Hello World!")
print(bolded_text)

Underlining text

To underline text, you use the underline() function.

Parameter

Returns: It returns a string containing the underlined text.

import css

underlined_text = css.underline("Hello World!")
print(underlined_text)

Converting color formats

pycss has functions that allows you to convert between Hex color codes and RGB color codes.

Hex to RGB

To convert hex color codes into RGB color codes, use the hex2rgb() function.

Parameter

1. hex_code - The hex code you want converted.

Returns: This function returns a tuple with the format (red, green, blue) to represent RGB.

import css

# Convert hex code
hex_code = "#ffc300"
rgb = css.hex2rgb(hex_code)

# Extract red, green, and blue from rgb
red, green, blue = rgb[0], rgb[1], rgb[2]

# Print them out
print("Red:", red)
print("Green:", green)
print("Blue:", blue)
print("RGB color code:", rgb)

Red: 255
Green: 195
Blue: 0
RGB color code: (255, 195, 0)

RGB to hex

To convert RGB color codes into hex color codes, use the rgb2hex() function.

Parameters

1. red - The red value in RGB.
2. green - The green value in RGB.
3. blue - The blue value in RGB.

Returns: This function returns a string with the converted hex code.

import css

# Convert RGB color code
red, green, blue = 255, 195, 0
hex_code = css.rgb2hex(red, green, blue)

# Print the converted hex_code out
print(hex_code)

#ffc300
