引导版本应该是 PyPy,而不是 PyPy3。PyPy 是用 Python 2 方言编写的。这是唯一一种不用担心贬值的情况,因为 PyPy 是 Python 2 方言解释器。PyPy3 是 Python 3 方言的实现,通常更适合在生产中使用,因为大多数包都在慢慢放弃对 Python 2 的支持。 最新的 PyPy3 支持 Python 的 3.5 特性,以及 f 字符串。然...

For example, say that you want to code a function that takes a number from 0 to 2 and return the strings "rock", "paper", or "scissors". Instead of writing the function right away, you start writing the following tests: Python test_game.py import unittest from game import rock_paper...
# Python程序:打印所有介于1和50之间且不可被2或3整除的整数foriinrange(1,51):ifi%2!=0andi%3!=0:print(i) Python Copy 在上面的代码中,我们使用了for循环遍历1到50之间的每一个整数,在循环体内部使用if条件语句来判断该整数是否可以被2或3整除。如果不能...
如果我们不能破解这个密文,我们可以假设密钥长度为 2 或 8 再试一次。 因为密钥是循环加密明文的,所以密钥长度为 4 意味着从第一个字母开始,密文中的每四个字母使用第一个子密钥加密,从明文的第二个字母开始的每四个字母使用第二个子密钥加密,依此类推。使用这些信息,我们将从由同一个子密钥加密的字母的密文中...

In this code snippet, the minus sign (-) in the first example is a unary operator, and the number 273.15 is the operand. In the second example, the same symbol is a binary operator, and the numbers 5 and 2 are its left and right operands....
