重现Python 中 TypeError: iteration over non-sequence 现在您已经了解了 TypeError 的原因,让我们在 Python 中重新创建非序列错误的迭代。 在 Python 2 中运行以下脚本会出现TypeError: iteration over non-sequence。 classBook:def__init__(self, name, author):self.name = name self.author = authorclassColl...
查询SQL的方法错了，导致返回值的处理也不对！ [图片]

Operating on Sequence Types 序列类型上的操作 We can iterate over the items in a sequence s in a variety of useful ways, as shown in Table 4.1. Table 4.1: Various ways to iterate over sequences Python Expression Comment for item in s iterate over the items of s for item in sorted(...

Since the next iteration is going to look at index 1 (which is the 3), the 2 gets skipped entirely. A similar thing will happen with every alternate element in the list sequence.Refer to this StackOverflow thread explaining the example See also this nice StackOverflow thread for a similar...
sequence is the name of the sequence you are iterating over. In this example, the sequence name is y, which is a list of months. Therefore, this example says, “For each value in y, print the value”. The second for loop example shows how to use the range function in combination ...
This option that is different is--run, and passing on arguments after the first non-option to the created binary, so it is somewhat more similar to what plainpythonwill do. Installation For most systems, there will be packages on thedownload pageof Nuitka. But you can also install it from...
