03.05.2021 · Python interprets objects separated by commas as a tuple. If you were to print the type of sea, you'd get tuple.. The .split() function is for str objects.It's not applicable for tuples. Also, based on the prompt you were given, you should be using sea =input() instead of defining the numbers. This will allow the person running the program to choose the numbers.

Consider for example the following SQL statement: SELECT a, b, c FROM my_table; In this case, fetchone () will return a three-tuple. Writing value, = fetchone () you are telling Python that you are expecting a one-tuple and you want that single item placed into value. If you were expecting the three-tuple, you'd have used column_a, column_b ...

24.04.2020 · 翻译：属性错误，tuple对象没有shape属性。这往往发生在我们对一个tuple类型数据，调用成员变量shape所致（a.shape 或 a.shape[]）。所以要查看调用发生处，看看自己的数据类型是不是有错。我们看代码import numpy as npa = np.zeros([5,5])#正确使用方式：print(a)print(type(a))print(ty...
