我正在尝试编写单词搜索/查找单词生成器，但我遇到了一些问题。此代码的目的是从用户输入中获取维度和单词，并生成随机单词搜索/查找单词。
问题是这些字母偶尔会相互覆盖。为了尝试阻止这种情况，我的函数中有这行代码：
lines[0][randCoO[0] - (i)][randCoO[1]] == '-':
该行属于函数 U
它旨在测试空间是否为空（由 ' - ' 填充）
我知道我应该尽量避免将我的整个代码放入其中，因为它可能很长而且读起来很烦人，但是请尝试帮助我
这是我的代码：
try:
dim=int(raw_input('How many letters high and long do you want your find-a-word? (It has to be <= 79) '))
except ValueError:
raise SystemExit, 'Dude, thats not a number!'
if dim > 79:
raise SystemExit, "\n That number is bigger than 79. It won't print to well. \n"
count=0
allwords = raw_input('What words do you want in your find-a-word?\n(Enter them all together seperated by a comma)')
allwords = allwords.upper()
allwords = allwords.split(', ')
nowords = len(allwords)
