我想将颜色随机化,并每隔几秒钟更改文本的颜色,所以我想确保我不使用相同的颜色。我怎么知道当前的文字颜色?

您可以定义颜色的set,并使用组和当前颜色的差异来获得仅包含不同颜色的组。然后将其转换为列表,并使用random.choice
选择一种新颜色。
import random
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
# Define a set of the colors.
COLORS = {RED, GREEN, BLUE}
color = RED # Current color.
for _ in range(50):
# The difference of `COLORS` and the set `{color}` is
# a set that doesn't contain `color`.
difference = COLORS - {color}
# Then you need to convert this set into a list in order
# to use `random.choice`.
color = random.choice(list(difference))
print(color)
