从上面的小程序可以看出,当用户每一次点击OK按钮时,都会触发一次界面读写事件,于是在while True的死循环中就会循环一次,之后程序将停留在Read语句上,等待着用户的下一次输入。 可能聪明的读者这时候会有质疑:为什么这里的这个死循环和以前学习的Python中死循环不一样呢?在普通的Python程序中,一旦进入死循环,程序立刻进...
Write a while loop in Python that prints user_num divided by 2 until user_num is less than 1. Sample output for the given program: 10.0 ,5.0, 2.5 .1.25 ,0.625 Write a PYTHON program that keeps a dictionary in which both keys and values are strings -- names of students and their c...
While this answer seems straightforward, the interesting question is:can we write a more complex for loop that has a longer loop body in a single line? This is much more difficult. While it’s possible to condense complicated algorithms in a single line of code, there’s no general formula...

Note that the start value, end value and step value need not be integers, but can be floating point numbers as well. If the loop variable was previously assigned in the program, its value will be replaced by the start value, it will not be evaluated. ...
