在很多的高级语言中都有for循环(for loop)。for语句是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to beexecutedrepeatedly。(作用:介绍了f...
A for-loop has two parts: a header specifying the iteration, and a body which is executed once per iteration. (for循环是什么构成的?) 是什么:在计算科学中,是针对特殊迭代对象的控制流语句,能够重复执行 怎么构成:一个头部(是可迭代对象)+ 每个对象的执行 本文的主要内容如下,其他Python入门内容请参考:...
x=x-(total_width-width)/2labels=['Trial 1','Trial 2','Trial 3']plt.bar(x,a,width=width,yerr=a_SD,tick_label=labels,label='Control')plt.bar(x+width,b,width=width,yerr=b_SD,tick_label=labels,label='Experimental')plt.legend()plt.show()exit ...
我们可以看到,这里的控制变量“i”用于等于0,也就是说while后面的条件永远为True,这个循环将会永远进行下去,你的屏幕上会不停地显示一行又一行的“In the loop...”,根本停不下来,而最后的Goodbye永远也不会被输出。唯一能终止程序的方法就是手动了,点击PyCharm的停止按钮或者control+C来外力终止程序。

In a for loop, the integer mentioned inside the range function is the range or the number of times the control needs to loop and execute the code in the for loop's clause. Note that the range() function's count starts from 0 and not from 1. That means that, in the above example,...
