链接:Python中的for循环,没你想的那么简单~ 一年四季,循环往复:说到底就是一个循环的问题 for语句实际上解决的是循环问题。在很多的高级语言中都有for循环(for loop)。 for语句其实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: In computer science, a for-...

This is where a nested for loop works better. The first loop (parent loop) will go over the words one by one. The second loop (child loop) will loop over the characters of each of the words. words=["Apple","Banana","Car","Dolphin"]forwordinwords:#This loop is fetching word from...

for i in range(10): if i == 5: break print(i) This will print numbers from 0 to 4 and then break out of the loop. The continue statement for num in range(10): if num == 5: continue print(num) Here, number 5 will be skipped, printing numbers: 0 1 2 3 4 6 7 8 9 ...
