python - ubuntu下eclipse+pydev报错

Question

程序源码如下：

<code>#coding =utf-8

def vowels_count(string):
    ret = 0
    for c in string:
        if c in "dskfhkfh":
            ret +=1
    return ret
s = "kjfhkjlf"
print vowels_count(s)
print range(len("hello world"))
</code>

在ubuntu下的eclipse+pydev环境下，会在第10行，即

<code>print vowels_count(s)
</code>

处提示有错。错误信息为(这个错误信息是显示在行号前)：

<code>Encountered "vowels_count" at line 10, column 7. Was expecting one of:     <NEWLINE> ...     "(" ...
 "[" ...     ";" ...     "," ...     "." ...     "+" ...     "-" ...     "*" ...     "/" ...     "//" ...     "<<" ...     ">>" ...     "%" ...     "^" ...
 "|" ...     "&" ...     "=" ...     ">" ...     "<" ...     "==" ...     "<=" ...     ">=" ...     "!=" ...     "+=" ...     "-=" ...     "*=" ...
 "/=" ...     "//=" ...     "%=" ...     "&=" ...     "|=" ...     "^=" ...     "<<=" ...     ">>=" ...     "**=" ...     "or" ...     "and"
 ...     "not" ...     "is" ...     "in" ...     "if" ...     ";" ...     "," ...
</code>

但是run还会有正确结果

<code>output:
5
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

</code>

既然能够正常运行，那么这只是 IDE 的 bug 而已（Python 是动态语言，因此 IDE 的静态分析很难完全做对）。如果你嫌烦，可以不用功能过于强大的 IDE，或者关掉这种提示。

又看了一下，也有可能是强制代码风格的信息（也就是代码风格问题）。
