工具/原料 PYTHON 方法/步骤 1 打开JUPYTER NOTEBOOK，新建一个PY文档。2 for i in range(5): print("ok")单单只是用一个FOR LOOPS，就会自动地打印相应的次数。3 for i in range(5): print("ok")for j in range(5): print("yes")当然我们也可以同时使用两个循环。但是这样没有太多的技巧在里...

Using a for loops in Python we can automate and repeat tasks in an efficient manner. So the bottom line is using the for loop we can repeat the block of statements a fixed number of times. Let’s understand this with an example. As opposed to while loops that execute until a condition...

3.While looping, you may want to perform different actions depending on the particular item in the list. This can be achieved by combining your loops with control flow (if/elsestatements) that might resemble the following: Make sure to keep track of your indentation or you may get confused!
