为什么“其他”是“其他”？给出无效语法错误的行？
我遇到此错误：
File "zzz.py", line 70
else:
^
SyntaxError: invalid syntax
导致问题的行在代码中用注释标记：
def FileParse(self, table_file):
vars={}
tf = open(table_file, 'r')
for line in tf:
if line.startswith("#") or line.strip() == "": pass
elif line.startswith("n_states:"):
self.n_states = str(line[9:].strip())
elif line.startswith("neighborhood:"):
self.neighborhood = str(line[13:].strip())
elif line.startswith("symmetries:"):
self.symmetries = str(line[11:].strip())
elif line.startswith("var "):
line = line[4:]
ent = line.replace('=',' ').\
replace('{',' ').\
replace(',',' ').\
replace(':',' ').\
replace('}',' ').\
replace('\n','').split()
vars[ent[0]] = []
for e in ent[1:]:
if e in vars: vars[ent[0]] += vars[e]
else:
vars[ent[0].append(int(e))]
else:
rule = line.strip().split(",")
for k in vars.keys():
if k in rule:
for i in vars[k]:
change = rule.replace(k, i)
change = [int(x) for x in change]
w.rules.append(Rule(change[:5],change[5])
else: # line which causes the problem
rule = [int(x) for x in rule]
w.rules.append(Rule(rule[:5],rule[5]))
tf.close()
self.parse_status "OK"
return w.rules
w.rules 是分配给“World”类的变量。
老实说，我不知道为什么我会得到这个。之前一切都很好，现在在其他缩进块中添加一些额外的指令后出现错误。
有什么想法吗？
I'm having this error:
File "zzz.py", line 70
else:
^
SyntaxError: invalid syntax
The line which causes the problem is marked with a comment in the code:
def FileParse(self, table_file):
vars={}
tf = open(table_file, 'r')
for line in tf:
if line.startswith("#") or line.strip() == "": pass
elif line.startswith("n_states:"):
self.n_states = str(line[9:].strip())
elif line.startswith("neighborhood:"):
self.neighborhood = str(line[13:].strip())
elif line.startswith("symmetries:"):
self.symmetries = str(line[11:].strip())
elif line.startswith("var "):
line = line[4:]
ent = line.replace('=',' ').\
replace('{',' ').\
replace(',',' ').\
replace(':',' ').\
replace('}',' ').\
replace('\n','').split()
vars[ent[0]] = []
for e in ent[1:]:
if e in vars: vars[ent[0]] += vars[e]
else:
vars[ent[0].append(int(e))]
else:
rule = line.strip().split(",")
for k in vars.keys():
if k in rule:
for i in vars[k]:
change = rule.replace(k, i)
change = [int(x) for x in change]
w.rules.append(Rule(change[:5],change[5])
else: # line which causes the problem
rule = [int(x) for x in rule]
w.rules.append(Rule(rule[:5],rule[5]))
tf.close()
self.parse_status "OK"
return w.rules
w.rules is variable which is assigned to "World" class.
To be honest I have no idea why I get this. Before everything was fine and now that error shows up after adding some extra instructions in other indented blocks.
Any ideas?

因为你遗漏了一个右大括号
Because you left out a closing brace
上一行
w.rules.append(Rule(change[:5],change[5])缺少右括号。The previous line,
w.rules.append(Rule(change[:5],change[5]), is missing a close paren.当你这样做时，还有另一个错字。您可能想要：

While you're at it, there is another typo. You probably want:

删除多余的空格/行并重新缩进 if/else 语句。这对我有用。
（我在这里尝试了其他解决方案，但没有一个有效。我的牙套很好。）
Remove extra spaces/lines and re-indent the if/else statements. This worked for me.
(I tried the other solutions here but none worked. My braces were fine.)
