you should almost certainly put theeval "$(pyenv init - bash)"line into.bash_profile, andnotinto.bashrc. Otherwise, you may observe strange behaviour, such aspyenvgetting into an infinite loop. See#264for details.

As we can see we are using a variablei, which represents every single element stored in the list, one by one. Our loop will run as many times, as there are elements in the lists. For example, inmyListthere are 6 elements, thus the above loop will run 6 times. 如我们所见,我们正在...

Improved: 18.161 ns per loop % Improvement: 99.8 % Speedup: 498.17x 4、跳过不相关的迭代 避免冗余计算,即跳过不相关的迭代。 # Example of inefficient code used to find # the first even square in a list of numbers def function_do_somethin...
We can also loop through a range of numbers without using the index number: num = 5 while num > 0: print(f"I will repeat myself {num} times") num -= 1 Output: I will repeat myself 5 times I will repeat myself 4 times
尽管如此,生成器在内存使用和性能方面都更好。它们允许函数避免临时再做所有的工作,当结果的列表很大或者在处理每一个结果都需要很多时间时,这一点尤其有用。生成器将在loop迭代中处理一系列值的时间分布开来。 尽管如此,对于更多高级的应用,它们提供了一个更简单的替代方案来手动将类的对象保存到迭代中的状态。 有...
图2-4:一条elif语句的流程图 如果age < 12是True并且name == 'Alice'是False,则elif子句执行。然而,如果两个条件都是False,则两个子句都被跳过。不能保证至少有一个条款会被执行。当有一串elif语句时,只有一个或没有一个子句会被执行。一旦发现其中一个语句的条件是True,其余的elif子句将被自动跳过。例如,...
