TypeError: 'range' object doesn't support item deletion

python 是个逐步迭代开发的过程,他不是向下兼容的,更不是向上兼容,版本不一致,好端端的程序就是不能运行了。

下面是在python 2中能运行,在Python 3中不能运行的代码。其实也很简单。但是这些边边角角的东西着实让人头疼。

>>> a=range(10)
>>> a
range(0, 10)
>>> del[a[1]]
Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    del[a[1]]
TypeError: ‘range‘ object doesn‘t support item deletion

报这个错:

其实只要这样修改下就OK了、

>>> a=list(range(10))
>>> a
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> del[a[1]]
>>> a
[0, 2, 3, 4, 5, 6, 7, 8, 9]
>>>

TypeError: &#39;list&#39; object cannot be interpreted as an integer

TypeError: 'list' object cannot be interpreted as an integer 类型错误,不能将list对象转换为一个整数. 错误代码,例如如下例子: args = [3,6] print(list(range(args))) range函数本应该需求,一个整数,或者一对范围,或者三个整数类型,才能构造一个iterable,这里直接将args这个列表传递给它是不行的,需要通过解压缩机制,更正后代码为: args = [3,6] print(list(ra

TypeError:&#39;dict&#39; object is not callable

TypeError:'dict' object is not callable 出现这种错误有两种可能: 1. 代码里重新定义了dict,比如 dict= {...},这时调用的是代码里定义的dict而不是python内置类型 2. 取字典内容时用了()而不是[].比如sdict("content_id"),应该是sdict["content_id"] TypeError:'dict' object is not callable
