当变量具有实际的颜色名称时，如何以颜色打印字符串？

def print_colored_string(text, color):
    colors = {
        'black': '\033[30m',
        'red': '\033[31m',
        'green': '\033[32m',
        'yellow': '\033[33m',
        'blue': '\033[34m',
        'magenta': '\033[35m',
        'cyan': '\033[36m',
        'white': '\033[37m'
    }
    reset = '\033[0m'
    
    if color in colors:
        colored_text = colors[color] + text + reset
        print(colored_text)
    else:
        print("Invalid color")

# 示例用法
print_colored_string("Hello, World!", "red")
print_colored_string("Hello, World!", "blue")
print_colored_string("Hello, World!", "green")
