One of the advantages of using the Python magic method is that it provides an easy way to make objects behave like built-in types. This means that you can avoid performing basic operations with ugly, anti-intuitive, and nonstandard methods. In some languages, this is usually done:If Instance.equals (other_instance): # do somethingYou should also do this in Python
Use try, cmdt, and else To make the Python program more "strong", using tpython
In the executed program, fatal errors may occur due to some reasons, such as input and output (for example, the input file name is incorrect and the relevant Code cannot be run .). At this time, you do not want the program to be hung up directly, but simply display some information to make
run to a maximum determined FPS value. The clock object will insert a small pause in the main game loop to ensure that our game program does not run too fast. If we don't have these pauses, our game will run as fast as the computer. It was really fast for the people who played the game. Calling the Tick () method of the clock object in the game loop will ensure that our game runs to a certain speed no matter how fast the computer runs. Create a Clock object with the following statement Fpsclock
Preface
In the previous article, we explained the installation of Anaconda in the Ubuntu environment and made a simple English word cloud.
Some students may try to change the article into Chinese, make the Chinese word cloud. I think we're going to get the results.
There are many differences between Chinese and English in coding, and when we do the English word cloud, in an article, the words are separated by a space,
but the Chinese language does

because it will soon be improved in the way that follows. More details for interested readers can read the original paper.
Now we have a bit-estimation method that is really bad. What improvements can we make? A direct idea is to use multiple independent hash functions. If each hash function outputs its own random dataset, we can record the longest leading 0-bit sequence. And then in the end we can get an average value for a more accurate estimate.
