贝果皮科弗米错误？

Question

当前代码的bug可能比我目前看到的要多，但我试图修复的是get_guess（）函数。目前，我已经将其编码为在“范围内的I…”中打印I，因为每当我输入猜测时，它会自动假定I=0并打印“您只能猜测数字”。我不确定为什么，因为0是它应该检查的数字列表的一部分。有没有办法解决这个问题？ 旁注，事情是正确的缩进，我只是不习惯这个网站的格式

我认为这可能是因为您正在函数中声明num_list generate_number(length)

因此，当您在函数外部请求num_list时，python不知道num_list是什么。将其声明为全局变量可以解决您的问题（但尚未测试） 是的，i=0，因为它是迭代器，而不是你猜到的数字。如果你想看看你的猜测，就写吧

print(guess[i],"You can only guess numbers.")

我会小心处理一些事情，不是吗 1.指定输入必须是字符串。如果输入一个不带引号的int，它将崩溃（至少对我来说是崩溃的），或者在将其传递给函数之前将其转换为string。它在尝试访问数组guess[i]时崩溃 2.注意以0开头的数字（例如02）。如果不另行指定，则强制转换为int会将其转换为2
