We then create a range that we want to loop through. In this case, we want to loop repeatedly through the numbers 1-3. So we use the range() function and pass in 1-4 as the parameter. Remember that the first parameter of a range() function is inclusive while the second parameter i...
game_objects = [I, O, J, L, T] #you can create as many as you want objects_color = [(255, 255, 0), (255, 0, 0), (0, 0 , 255), (255, 255, 0), (128, 165, 0)] 由于我们已经完成了基本的起始文件,也就是说,我们已经理解并创建了我们的游戏对象,在下一节中,我们将开始为...
loop.call_soon(callback, argument): 这安排一个回调尽快被调用。当控制返回到事件循环时,call_soon()(docs.python.org/3/library/asyncio-eventloop.html)返回后调用回调。 loop.time(): 这将根据事件循环的内部时钟返回当前时间作为float值(docs.python.org/3/library/functions.html)。 asyncio.set_event_loo...
First-Class ObjectsIn functional programming, you work almost entirely with pure functions that don’t have side effects. While not a purely functional language, Python supports many functional programming concepts, including treating functions as first-class objects. This...

$(TARGET): $(OBJECTS) $(CC) $(CFLAGS) -o $@ $^ %.o: %.c $(CC) $(CFLAGS) -c -o $@ $< clean: rm -f $(OBJECTS) $(TARGET) 在上述示例中,您需要将`CC`变量设置为交叉编译工具链的编译器名称。`CFLAGS`变量用于设置编译选项。`TARGET`变量是要生成的最终可执行文件的名称。`SOURCES`变...
Now, we will discuss another function that can help us achieve a nested for loop in one line, the exec() function. The exec() function in Python is used for the dynamic execution of Python programs that are stored in strings or code objects, and It allows us to execute dynamically gener...
To summarize, a for statement is used when the maximum number of iterations is known in advance. Use a while statement when the loop should keep running until something changes. Before You Begin If you have not already done so, create a Linode account and Compute Instance. See our Getting ...
from collections import namedtuplePerson = namedtuple('Person', 'name age job')Once the template is created, you can use it to create namedtuple objects. Let’s create 2 namedtuple’s for2 Persons andprint out their representation.Person = namedtuple('Person', 'name age job')Mike = Person(...
