List data types and common operations of python, and list data types of python A list is the most common Python data type. It can appear as a comma-separated value in square brackets. Each element in the list is assigned a number-its location, or index. The first index is 0,

the C language, Python's long Integer does not refer to the positioning width, i.e. python does not limit the size of long integer values, but in fact, because of the limited machine memory, we use a long integer value can not be infinite.Note that, since Python2.2, Python automatically converts integer data to long integers if an integer overflows, so it does not cause any serious consequences if you do not add the letter L after long integer data.F

Reply to discussion (solution) is not a combination of other types.Is the most basic, and is the type of PHP comes with. Wher

Sometimes, you may face the issue of not knowing how many variables there will be in the data in the future, and write all the variables at once, or when you are faced with variables, it is obviously not a good method to constantly modify the class source code to expand new data records. at this time, you can use the index + binding method to solve the problem: the data
