无效了Syntex（需要帮助！）

我想创建一个元组列表，我越来越无效了Syntex：无效了Syntex（需要帮助！）

def match_enzymes(strand, enzymes, sequences): 
'''(str, list of str, list of str) -> list of (str, list of int) tuples 

Return a list of tuples where the first item of each tuple is the name of a restriction enzyme and the second item is the list of indices of the restriction sites that the enzyme cuts. 

>>> 
>>> 
>>> 
''' 

list_of_tuples = [] 

for i in range(len(enzymes)): 
    list_of_tuples.append((enzymes[i], restriction_sites(strand, sequence[i])) 

return list_of_tuples

缩进，你会得到无效的语法。 –

[“预期的缩进块”错误？]（http://stackoverflow.com/questions/19657576/expected-an-indented-block-error） –

两个问题：

1）你缺少右括号中：

list_of_tuples.append((enzymes[i], restriction_sites(strand, sequence[i])) #<--!!!

2）如果您的代码缩进这样你的代码是不是目前
