我设法在python上创建了一个无限的while循环(它不断地反复显示高分位),并且在纠正它时遇到了麻烦,有什么想法吗?
我在高分位之后添加了一个中断并停止了无限循环,但是程序会要求人们在他们估算出他们的选择后按下退出按钮,即使他们没有按下 0。
#high scores
#demonstrates list methods
scores = []
choice = None
while choice != "0":
print(
"""
High Scores
0 - Exit
1 - Show Scores
2 - Add a Score
3 - Delete a Score
4 - Sort Scores
"""
)
choice = input("Choice: ")
print()
#exit
if choice == "0":
print("Goodbye")
#list high scores table
elif choice == "1":
print("High Scores")
for score in scores:
print(score)
#add a score
elif choice == "2":
score = int(input("What score did you get?: "))
scores.append(score)
#remove a score
elif choice == "3":
score = int(input("Remove which score?: "))
if score in scores:
scores.remove(score)
else:
print(score, "isn't in the high score list.")
#sort scores
elif choice == "4":
scores.sort(reverse=True)
#some unknown choice
else:
print("Sorry, but", choice, "isn't a valid choice.")
input("\nPress the enter key to exit.")
谢谢。
