How to set only one word in a specific color using Click.secho

Question

I'm using the click module.

pip install click

This gives me red text

import click
click.secho('Error: This error is ...xx', fg='red')

Now I want that only 'Error:' is shown in red. How can I do this using click.secho?

Answer 1

Use click.echo with click.style

click.echo(click.style("Error", fg="red") + ": This error is...")

Answer 2

You can use the built in secho command with the nl (new line) flag.

In your specific use case it would look like

click.secho('Error', fg='red', nl=False) # This will prevent the secho statement from starting a new line
click.echo(': This error is ...xx')

This will give you the output you wanted

Answer 3

From click documentation for the echo method

In addition to that, if colorama is installed, the echo function will also support clever handling of ANSI codes.

From colorama documentation

print('\033[31m' + 'some red text')
print('\033[30m') # and reset to default color

Thus, combining, you should have something like the following

click.echo('\033[31m' + 'Error:' + '\033[30m' + ' This error ... ')

to get what you were looking for.
