print(f"While loop execution time: {while_loop_time:.6f} seconds") Output: Basically both while loops and for loops have their different advantages based on the conditions: Use a while loop when the total number
The program checks if the number is 0 and returns 1(factorial of 0 is 1). Then thewhile loopchecks the condition (n >=1) to see if our n is equal to 1 or greater than 1. Each time when this condition is TRUE, our program computes the formula in the loop block Let’s use the...

上述图表在几个基准上比较了 Python(CPython 3)、PyPy、Codon 和 C++ 的性能。y 轴显示 Codon 实现相对于 CPython 实现的加速。MIT/EXALOOP/UNIVERSITY OF VICTORIA/ACM 除了基因组学,Codon 还可以应用于处理海量数据集的类似应用程序,以及基于 Python 的编译器支持的 GPU 编程和并行编程等领域。事实上,Codon...
It is arguably also one of the most intuitive ones to understand: if you think of the name of this loop, you will quickly understand that the word "while" has got to do something with "interval" or a "period of time". As you already know by now, the word "loop" refers to a ...
