python报错 ValueError: dictionary update sequence element #0 has length 1； 2 is require

字符串转字典要用eval（），这个方法很多书上都没有介绍， 有关eval（）的用法，传送门： ss = ['a','bc','def']>>> dict(ss)Traceback (most recent call last): File "", line 1, in ValueError: dictionary update sequence element #0 has length 1; 2 is required>>> eval(ss)Traceback (most recent call last): File "", line 1, in TypeError: eval() arg 1 must be a string, bytes or code object>>>>>> ss = ['aa','bc','def']>>> dict(ss)Traceback (most recent call last): File "", line 1, in ValueError: dictionary update sequence element #2 has length 3; 2 is required>>> ss = ['a','bc','de']>>> dict(ss)Traceback (most recent call last): File "", line 1, in ValueError: dictionary update sequence element #0 has length 1; 2 is required>>> ss = ['aa','bc','de']#改为2个字符就好啦！>>> dict(ss){'a': 'a', 'b': 'c', 'd': 'e'}>>> ss = ['awed','webc','wede']>>> dict(ss)Traceback (most recent call last): File "", line 1, in ValueError: dictionary update sequence element #0 has length 4; 2 is required>>>

这个仅仅是因为，需要转换的字符串不是2位!
