is_divisible(6,3) True 在函数内部,==运算符的结果是一个布尔值,因此我们可以通过直接返回它来更简洁地编写这个函数。 defis_divisible(x, y):returnx % y ==0 布尔函数通常用于条件语句中。 ifis_divisible(6,2):print('divisible') divisible 可能会想写成这样: ifis_divisible(6,2) ==True:print(...
A number is even if it is perfectly divisible by 2. When the number is divided by 2, we use the remainder operator % to compute the remainder. If the remainder is not zero, the number is odd. Source Code # Python program to check if the input number is odd or even. # A number ...

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...

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...
print('Please enter a number') # Code: https://www.py4e.com/code3/fahren2.py Python starts by executing the sequence of statements in thetryblock. If all goes well, it skips theexceptblock and proceeds. If an exception occurs in thetryblock, Python jumps out of thetryblock and execut...
for循环可以通过语句break提前中断。for循环的剩余部分可以使用语句continue跳过。 [输入] source_code/appendix_c_python/example12_break_continue.py for i in range(0,10): if i % 2 == 1: #remainder from the division by 2 continue print 'The number', i, 'is divisible by 2.' for j in ran...
输出将完全类似于本文前面看到的使用名为number_divisible_by_three的列表时的for循环的输出: 正如你在这个例子中看到的,你可以使用step参数增加到一个更高的数值。这叫做递增 用range()实现递增 如果你想实现递增,那么你需要将step设为正数。为了解这个的现实意义,键入以下代码: ...
