How this nesting for loop works in Python?-CodePudding

I can't understand the second for loop:

for k in range(2, n//2   1):
    print(n%k, end=" ")

How did this formula produce such result?

CodePudding user response：

range() has multiple parameters, first is start, second is stop, third is step (which is not present in this example, so the default value is used: 1).

So your range will generate numbers from 2 to n//2 1.

CodePudding user response：

The second for loop prints the reminders of dividing n by all of the numbers from 2 to n/2.
