In other words, the above functions is just one step away from the generator. To turn the return value of the fib function into the generator, just change the 'print(b) to yield b. deffib(max): n, a, b= 0, 0, 1whilen <max:yieldb a, b= b, a +b n= n + 1 这就是定义...
The Magic Number Generator ExampleOften, when using the subprocess module, you’ll want to use the output for something and not just display the output as you have been doing so far. In this section, you’ll use a magic number generator that outputs, well, a magic number....
So before runtime, array is re-assigned to the list [2, 8, 22], and since out of 1, 8 and 15, only the count of 8 is greater than 0, the generator only yields 8. The differences in the output of g1 and g2 in the second part is due the way variables array_1 and array_...
本文展示了一个极简 GPT,它只有 2 个 token 0 和 1,上下文长度为 3; 这样的 GPT 可以看做是一个有限状态马尔可夫链(FSMC)。 我们将用 token sequence 111101111011110 作为输入对这个极简 GPT 训练 50 次, 得到的状态转移概率符合我们的预期。 例如 ...
In the command above, you tell pip to install the packages listed in requirements.txt into your current environment. The package versions will match the version constraints that the requirements.txt file contains. You can run pip list to display the packages you just installed, with their ...

An object falls into the latter category if it responds to the iter built-in with an object that advances in response to next. The generator comprehension expression we saw earlier is such an object. I’ll have more to say about the iteration protocol later in this book. For now, keep ...
