SyntaxError：语法无效（Python 3.2）

Question

我有一个函数，它将在字符串元组中插入空格，以便所有字符串的len相等。我还有一个函数，可以处理字符串元组和一些格式化信息，并将它们组合为一个字符串元组

#code for equal string length

def insertSpace(self,content):

    max = 0

    for string in content:

        temp = len(string)

        if temp > max:

            max=temp

    retstring = ("",)

    for string in content: 

        retstring = retstring + (" "*(max - len(string)+1,)

    return self.combine(retstring,content,bold=False,newline=False)

#code for combine

def combine(self,leftside,rightside,bold=False,newline=False):

    if bold is True:

        bold = '<B>'

        boldend = '</B>'

    else:

        bold = ''

        boldend = ''

    if newline is True:

        newlinechar = '<br>'

    else:

        newlinechar = ''

    return tuple((bold +"{0}"+boldend+"{1}"+newlinechar).format(x,y) for x,y in zip(leftside,rightside))

执行此脚本会导致

File "mypythonfile.py", line 108

return self.combine(retstring,content,bold=False,newline=False)

     ^

SyntaxError: invalid syntax

我试图将值存储在变量中，但没有任何改变。大概有点简单，但我看不到。

您错过了)此行的结束语：retstring = retstring + ("&nbsp;"*(max - len(string)+1,))&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ^&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; |&nbsp;编辑：在您的代码：>>> 'retstring = retstring + ("&nbsp;"*(max - len(string)+1,)'.count("(")3>>> 'retstring = retstring + ("&nbsp;"*(max - len(string)+1,)'.count(")")2
