Is it possible to print using different colors in ipython's Notebook?

Question

Is it somehow possible to have certain output appear in a different color in the IPython Notebook? For example, something along the lines of:

 print(\"Hello          


        

Answer 1

Not with raw Python print. You will have to define a _repr_html_ on an object and return it or call IPython.lib.display(object_with_repr_html).

I guess you could overwrite the built-in print to do it automatically...

You could inspire from http://nbviewer.ipython.org/5098827, code in a gist on github, ML discussion here.

Here's a quick hack:

from IPython.display import HTML as html_print

def cstr(s, color='black'):
    return "<text style=color:{}>{}</text>".format(color, s)

left, word, right = 'foo' , 'abc' , 'bar'
html_print(cstr(' '.join([left, cstr(word, color='red'), right]), color='black') )

[out]:

If you just want a single color: html_print(cstr('abc', 'red'))

You can use this library termcolor and you can get all other official libraries of python in PyPi.

1. pip install termcolor
2. then goto ipython

Code

from termcolor import colored
print(colored('hello', 'red'), colored('world', 'green'))
print(colored("hello red world", 'red'))

Output:

hello world
hello red world

The first argument is what you want to print on console and second argument use that color.

See the documentation in pypi.python.org for more information

Answer 4

There is the colored library (pip install colored), which you can use to modify a string to get color codes to modify how it is printed. Example use:

import colored
print(colored.bg("white") + colored.fg("red") + "Hello world!")

Answer 5

Taken from: Standard for ANSI Colors in Terminals

This snippet can show you all the colors in one row:

RESET = "\x1b[0m"
print("To reset attributes: \\x1b[0m\n")
for i in range(0, 8):
    print("\x1b[1;3{0}m\\x1b[1;3{0}m{1} \x1b[0;3{0}m\\x1b[0;3{0}m{1} "
          "\x1b[1;4{0};3{0}m\\x1b[1;3{0};4{0}m{1}".format(i, RESET))

Answer 6

In the Jupiter notebook, we can use a color marker to print the output in different colors There are three ways that we can use a color marker.

let's see how to print a yellow color in a notebook.

1. print('\033[93m output')
2. print('\033[93m' 'output')
3. print('\033[93m' + 'output')

Some of the colors are :

• yellow = '\033[93m'
• green = '\033[92m'
• red = '\033[91m'
• blue = '\033[94m'
• pink = '\033[95m'

you can change the last number and get other colors as well.
