我试图解决一些已经存在的关于我的错误的问题,但他们都没有做到这一点。 这是我尝试运行的代码:
from random import *
location1 = randint(0,7)
location2 = location1 + 1
location3 = location2 + 1
guess = None
hits = 0
guesses = 0
isSunk = False
while (isSunk == False):
guess = raw_input("Ready, aim, fire! (enter a number from 0-6): ")
if (guess < 0 | guess > 6):
print "Please enter a valid cell number!"
else:
guesses = guesses + 1;
if (guess == location1 | guess == location2 | guess == location3):
print "HIT!"
hits = hits + 1
if (hits == 3):
isSunk = True
print "You sank my battleship!"
else:
print "MISS!"
stats = "You took " + guesses + " guesses to sink the battleship, " + "which means your shooting accuracy was " + (3/guesses)
print stats
我得到的错误是:
Traceback (most recent call last):
File "battleship.py", line 13, in <module>
if (guess < 0 | guess > 6):
TypeError: unsupported operand type(s) for |: 'int' and 'str'
我该如何解决这个问题?

在Python |
中是二进制OR。您应该使用or
运算符,就像这样
if guess == location1 or guess == location2 or guess == location3:
这条线也必须改变
if (guess < 0 | guess > 6):
到
if guess < 0 or guess > 6:
引自Binary bit-wise operator documentation,
|
运算符产生其参数的按位(包含)OR
,它必须是普通或长整数。参数将转换为通用类型。
但是,通常这句话就是这样写的
if guess in (location1, location2, location3):
此外,raw_input
返回一个字符串。所以你需要明确地将它转换为像这样的int
guess = int(raw_input("Ready, aim, fire! (enter a number from 0-6): "))
请注意,Python中不需要;
来标记语句的结尾。

您正在使用二进制OR运算符。只需更换“|”用“或”,它应该可以正常工作。
