我的游戏有很多变量错误没有被定义

Question

Traceback (most recent call last):
  File "\\FS2StratfordAC\ALIANWAR$\My Documents\Computing\A453 Controlled Assessment\Python\Task 3\dice game task 3 v2.py", line 52, in <module>
    print ("Your total is ", str_total)
NameError: name 'str_total' is not defined*

这是我的计划的一半。

if dice1 ==dice2:
    print (p1 +(" your skill is " + p1skill))
    print (p1 +(" your skill is " + p1str))
    print (p2 +(" your skill is " + p2skill))
    print (p2 +(" your skill is " + p2str))
if dice1 > dice2:
    str_total = (str_mod + p1str)
    skill_total=(skill_mod + p1skill)
    print (p1+ "Strength: " + str(str_val))
    print (p1+ "Skill: " + str(skill_val))
    print (p2+ "Strength: " + str(str_val))
    print (p2+ "Skill: " + str(skill_val))
if dice2 > dice1:
    str_total = (str_mod+p2str)
    skill_total=(skill_mod+p2skill)
    str_total = (str_mod+p2skill)
    str_total=(skill_mod + p1str)
    skill_total = (skill_mod - p1skill)

print ("Your total is ", str_total) 
print ("Your total is ", skill_total)

还有其他未定义的东西，如第14行和第21行，未定义。任何帮助，将不胜感激。谢谢; D。

如果dice1 == dice2为真，则您永远不会设置str_total和skill_total。

当dice2 > dice1为真时，您设置str_total和skill_total 两次。
