not define its own Equals method, it inherits the Equals method of the object class, and the implementation code for the Equals method of the object class is as follows:Boolean equals (Obejct o) {This==o;}This means that if a class does not define its own Equals method, its default Equals method (inherited from the object class) is using the = = operator, and whether the object pointed to by the two variables is the same object, using equals and using = = will get the same result. If the compar

Bash CookBook (1)-basics, bashcookbook Bash was written by brian Fox in January 10, 1988 out of Richard Stallman's suggestion. 1. Run the template: Interactive Login shell, bash reads and executes/etc/profile after login. Then read ~ /. Bash_profile ,~ /. Bash_login ,~ /. Profile, the first executable is found to be executed. When you log out, it will read and execute ~ /. Bash_logout. Interactive non-login startup will read and execute ~ /. B

Page elementsUse the Text-align property to center the text in block-level elements. When Margin-left and Margin-right are set to auto, the element is centered relative to the parent element. However, some of the newer browsers that are popular today are not able to render this appearance correctly, such as IE5 and Netscape Navigator. If you use the th element in an HTML table, the contents of the cell are centered by default. On the basis of horizontal centering, you can center vertically and n

first list (such as L[B1] 's head), as H.2 if H does not appear at the end of the other list, output it and remove it from all lists, then go back to step 1; otherwise, take the head of the next list as H and proceed with the step.3 Repeat the above steps until the list is empty, or you can no longer find out which elements to output. If this is the case, then the algorithm ends; if it is the latter case, it means that the inheritance relationship cannot be built, and Python throws an exception

1. Tuple unpacking and decompression sequence assignment　　Any sequence (or an iterative object) can be extracted and assigned to multiple variables by a simple assignment statement. The only prerequisite is that the number of variables must be the same as the number of elements in the sequence.　　1. Parallel Assignment:>>> x = (1, 2>>> A, b = x #>>> a1>>> b 22. Use the * operator to disassemble an iterative object as a function parameter:>>> Divmod (8) # 20 for the remainder of 8, 2 * 8 + 4

Python cookbook (data structures and algorithms) keeps the dictionary orderly. This example describes how to keep the dictionary in order by using Python. We will share this with you for your reference. The details are as follows: Problem:When creating a dictionary and performing iteration or serialization operations on the dictionary, you can also control the order of its elements; Solution:You can use the OrderedDict class in the collections module

Python cookbook (data structure and algorithm) is used to break down elements from any length of iteratable objects. This example describes how to use python to break down elements from iteratable objects of any length. We will share this with you for your reference. The details are as follows: N elements are extracted from an Iterated object, but the length of the iterated object may exceed N, resulting in an exception of "too many decomposition valu
