This is How You Color Print Out in Python

Many Python programmers depend on printing out statements on console, as a GUI isn’t always necessary. The issue sometimes is that a black and white console doesn’t help much when one has several console windows opened and running different functions. For example:

Honestly, you are not going to see what’s wrong (or right) easily when everything is just white on a black background.

So here it comes a library to help us out, fortunately! It’s called Termcolor. So let’s install it via python -m pip install termcolor command.

How to use it

It’s pretty simple. As simples as Python.

from termcolor import colored
print(colored('Hello', 'red'), colored('Medium', 'yellow'), colored('world', 'green'))

Before and after

Regular printing vs Termcolor printing

Using try and except

from termcolor import colored
try:
    int('Hello World')
    print(colored('Success!', 'green'))
except Exception as E:
    print(colored(str(E), 'red'))

Printing an exception in red

from termcolor import colored
try:
    int('10')
    print(colored('Success!', 'green'))
except Exception as E:
    print(colored(str(E), 'red'))

Printing a success try in green

Printing an exception in color and bold

from termcolor import colored, cprint
import sys
try:
    int('Hello World')
    print(colored('Success!', 'green'))
except Exception as E:
    cprint(str(E), 'red', attrs=['bold'], file=sys.stderr)

Printing an exception in red and bold

Printing try and exception in red and green backgrounds

from termcolor import colored, cprint
try:
    int('Hello World')
    print(colored('Success', 'green', attrs=['reverse', 'blink']))
except Exception as E:
    print(colored(str(E), 'red', attrs=['reverse', 'blink']))

Printing an exception in red background

from termcolor import colored, cprint
try:
    int('10')
    print(colored('Success', 'green', attrs=['reverse', 'blink']))
except Exception as E:
    print(colored(str(E), 'red', attrs=['reverse', 'blink']))

Printing a success try in green background

Conclusion

This library definitely helps us easily checking what’s going on in the code and on the console window without much effort, by just adapting the print statement a bit.
