如果计算机随机选取某个字母,它应该返回某一行,但它只选择一个实例反复重复,即使满足打印另一个句子的条件
import random
Player_Score = 0
Computer_Score = 0
while Player_Score < 5 or Computer_Score < 5:
Player_object = input("Would you like to choose R, P, or S?")
Computer_object = str(random.sample(set(["R", "P", "S"]), 1))
if Player_object == "R" or Player_object == "r":
if str(Computer_object) == "R":
print("You have chosen " +Player_object+ " and the Computer chose " +str(Computer_object)+ ".You have tied with the Computer and neither of you have scored a point.")
elif str(Computer_object) == "P":
Computer_Score = Computer_Score + 1
print("You have chosen " +Player_object+ " and the Computer chose " +str(Computer_object)+ ". You have been beaten by the Computer and it has scored a point.")
else:
Player_Score = Player_Score + 1
print("You have chosen " +Player_object+ " and the Computer chose " +str(Computer_object)+ ".You have beaten the Computer scored a point.")
此代码返回以下结果:
Would you like to choose R, P, or S?R
You have chosen R and the Computer chose ['R'].You have beaten the Computer scored a point.
Would you like to choose R, P, or S?R
You have chosen R and the Computer chose ['P'].You have beaten the Computer scored a point.
Would you like to choose R, P, or S?R
You have chosen R and the Computer chose ['S'].You have beaten the Computer scored a point.
Would you like to choose R, P, or S?R
You have chosen R and the Computer chose ['S'].You have beaten the Computer scored a point.
Would you like to choose R, P, or S?R
You have chosen R and the Computer chose ['R'].You have beaten the Computer scored a point.
Would you like to choose R, P, or S?R
You have chosen R and the Computer chose ['P'].You have beaten the Computer scored a point.
Would you like to choose R, P, or S?
str(random.sample(set(["R", "P", "S"]), 1))
返回"['S']"
,而不是'S'
,因此代码总是进入else条件相反,请尝试
random.sample("RPS", 1)[0]
,它将返回列表的第一个(也是唯一的)元素或使用random.choice('RPS')
