Question

ST = 5
statAdd = 5

我输入的内容更多，但没有一个是相关的，所以我只是复制了它。

while statAdd > 0:
    addStat = raw_input("""You may distribute %s points to your base stats. Which do you add to?
""" %(statAdd))
    if addStat == 'strength':
            pointDeduction = raw_input("How many points do you wish to add to Strength? (Up to %s points)" %(statAdd))
            if pointDeduction <= statAdd:
                    ST += pointDeduction
                    statAdd -= pointDeduction
            else:
                    print "You do not have that many points to distribute to Strength."

你会认为它应该添加积分，但我一直得到同样的错误＆＃34;你没有那么多积分来分配力量＆＃34;当我明显这样做的时候我在这里做错了什么？

Answer 1

尝试将输入转换为int？否则它是一个字符串，对它进行算术运算会导致意想不到的结果。

     while statAdd > 0:
    addStat = int(raw_input("""You may distribute %s points to your base stats. Which do you add to?  """ %(statAdd)))
    if addStat == 'strength':
            pointDeduction = int(raw_input("How many points do you wish to add to Strength? (Up to %s points)" %(statAdd)))
            if pointDeduction <= statAdd:
                    ST += pointDeduction
                    statAdd -= pointDeduction
            else:
                    print "You do not have that many points to distribute to Strength."

Answer 2

raw_input返回一个字符串。

如果存在prompt参数，则将其写入标准输出而不带尾随换行符。然后该函数从输入中读取一行，将其转换为字符串（剥离尾随换行符），然后返回该行。

您的if pointDeduction <= statAdd:语句正在进行此比较：

"5" <= 5

这将返回False

要解决此问题，您需要使用int包装输入语句（如果您只允许整数）。

addStat = int(raw_input("""You may distribute %s points to your base stats. Which do you add to?  """ %(statAdd)))

在python 2.x中，raw_input()返回一个字符串，因此在其上执行的操作就像不能工作一样。你应该使用普通input()代替（在第二个），它在Python 2.x中自动对输入执行eval：

while statAdd > 0:
addStat = raw_input("""You may distribute %s points to your base stats. Which do you add to?""" %(statAdd))
if addStat == 'strength':
        pointDeduction = input("How many points do you wish to add to Strength? (Up to %s points)" %(statAdd))
        if pointDeduction <= statAdd:
                ST += pointDeduction
                statAdd -= pointDeduction
        else:
                print "You do not have that many points to distribute to Strength."

这应该可行。注意，在Python 3.x中，input（）返回一个字符串，而eval（input（））将返回int。
