用户可以在运行之前检查 shell 脚本,甚至可以使用git checkout锁定特定的修订版本。 遗憾的是,pyenv 不能在 Windows 上运行。 安装pyenv 后,将其与运行的 shell 集成在一起是很有用的。我们通过向 shell 初始化文件(例如,.bash_profile)添加以下内容来实现这一点: ...
if [condition to check]: [instruction set to execute if condition is true] 鉴于Python 的可读性,你可能已经猜到条件语句的工作原理:当给定程序的执行达到条件语句并检查if语句中的条件时,如果条件为真,则将执行缩进的指令集在if语句内部;否则,程序将简单地跳过这些指令并继续执行。 在if语句内部,我们可以检...
This function does a quicker # prime number check before calling rabinMiller(). if (num < 2): return False # 0, 1, and negative numbers are not prime. 当num不小于2时,我们也可以使用LOW_PRIMES列表作为测试num的快捷方式。检查num是否能被所有小于 100 的质数整除不会明确地告诉我们这个数是否是...
print(is_even(42)) print(is_even(31)) Output: True False I have executed the above example code and added the screenshot below. In this code, theis_evenfunction takes a number as input and uses the modulo operator to check if it is divisible by 2. If the remainder is 0, the func...
# When finding factors, you only need to check the integers up to # MAX_KEY_LENGTH: for i in range(2, MAX_KEY_LENGTH + 1): # Don't test 1: it's not useful. if num % i == 0: factors.append(i) otherFactor = int(num / i) if otherFactor < MAX_KEY_LENGTH + 1 and ...
在这段代码中,使用if语句来判断上述条件,如果同时为真,则显示相应的消息。 类图表示 这段代码的逻辑可以用类图表示,尽管我们并没有使用类,但可以简化地将其表示为: NumberChecker+ number: int+ is_divisible_by_3: bool+ ends_with_3: bool+check_conditions() ...
