Python’s for loops are quite flexible and powerful, and you should generally prefer for over while if you need to iterate over a given collection. However, translating the for loop into a while loop, like above
Definite Iteration: When we know how many times we wanted to run a loop, then we use count-controlled loops such as for loops. It is also known as definite iteration. For example, Calculate the percentage of 50 students. here we know we need to iterate a loop 50 times (1 iteration fo...
A nested loop is a loop inside the body of the outer loop. The inner or outer loop can be any type, such as awhile looporfor loop. For example, the outerforloop can contain awhileloop and vice versa. The outer loop can contain more than one inner loop. There is no limitation on ...
In the above example the loop is terminated when x becomes 5. Here we use break statement to terminate the while loop without completing it, therefore program control goes to outside the while - else structure and execute the next print statement. Flowchart: Previous:Python For Loop Next:Pytho...
message ='And now for something completely different' 当你执行赋值语句时,没有输出。Python 会创建变量并赋予它一个值,但赋值语句没有可见的效果。然而,在创建变量后,你可以将其作为表达式使用。因此我们可以这样显示message的值: message 'And now for something completely different' ...
