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...
Baseline: 32.158 ns per loop Improved: 16.040 ns per loop % Improvement: 50.1 % Speedup: 2.00x 可以看到使用列表推导式可以得到2倍速的提高 2、在外部计算长度 如果需要依靠列表的长度进行迭代,请在for循环之外进行计算。 # Baseline version (Ineffici...

Example 1 - Using range function to loop n times The example here iterates over the range of numbers from 1 to 10 and prints its value. However, if it reaches the number divisible by 5, it will break the loop. Note that in this case, the statement inside the else block will not be...

Example 1:Use nested for loop to print numbers in patterns Let’s use the nested for loop to print the following pattern: 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 Each number is printed a number of times corresponding to its number itself. ...
