from termcolor import colored, cprint

text = colored("Hello, World!", "red", attrs=["reverse", "blink"])
print(text)
cprint("Hello, World!", "green", "on_red")

print_red_on_cyan = lambda x: cprint(x, "red", "on_cyan")
print_red_on_cyan("Hello, World!")
print_red_on_cyan("Hello, Universe!")

for i in range(10):
    cprint(i, "magenta", end=" ")

cprint("Attention!", "red", attrs=["bold"], file=sys.stderr)

# You can also specify 0-255 RGB ints via a tuple
cprint("Both foreground and background can use tuples", (100, 150, 250), (50, 60, 70))

Overrides

Terminal colour detection can be disabled or enabled in several ways.

In order of precedence:

Calling colored or cprint with a truthy no_color disables colour.
Calling colored or cprint with a truthy force_color forces colour.
Setting the ANSI_COLORS_DISABLED environment variable to any non-empty value disables colour.
Setting the NO_COLOR environment variable to any non-empty value disables colour.
Setting the FORCE_COLOR environment variable to any non-empty value forces colour.
Setting the TERM environment variable to dumb, or using such a dumb terminal, disables colour.
Finally, termcolor will attempt to detect whether the terminal supports colour.
