玩家输入字符（例如火星人）后，就会发生此错误：
在第2行的文件“ C：/Users/megam/Desktop/Martians/Martians.py”
character = input（str（“ martian，plutonian，human or dog \ n >>”））＃这会询问玩家他们想玩什么角色
文件“”，第1行，位于
NameError：未定义名称“火星人”
最佳答案
首先，您应该修复意图。
其次，对于火星人，狗，冥王星和人类，您必须将if character=="martian":从:更改为==。
if character=="martian": # This makes the following only occur if the player inputs "martian"
strength += 3 #This adds 3 to the value of strength
speed +=2 #This adds 2 to the value of speed
if character=="plutonian": #This makes the following only occur if the player inputs "plutonian"
heart_rate+=7 #This adds 7 to the value of heart rate
height1+=1 #This adds 1 to the value of height
if character=="human": #This makes the following only occur if the player inputs "human"
heart_rate+=3 #This adds 3 to the heart rate value
if character=="dog":
height-=3 #This adds 3
你也应该改变
character = input(str("martian,plutonian,human or dog\n>>"))至character = raw_input(str("martian,plutonian,human or dog\n>>"))
