A brief analysis of break continue exit () pass in Python

1. Break

Break is to terminate this cycle, such as you many while loop, you write a break in one of the while loop, satisfies the condition, only terminates this while inside the loop, the program jumps to the upper layer while loops continues to go down

Example with a simple for loop

For I in range (10):
    Print ("-----%d-----"%i)
    For j in Range (10):
        If J > 5:
            Break
        Print (j)
When we meet j>5, the second layer of for does not loop, continue to jump to the previous layer of the loop

2, continue
Continue is the time to loop to this point, to perform some of the operations continue here, after the execution, continue to loop to meet the conditions of this layer of the loop need to do, do not terminate this layer of loop
The above example makes a change

For I in range (10):
    Print ("-----%d-----"%i)
    For j in Range (10):
        If J > 5 and J <= 8:
            Print ("I am continue special")
            Continue
        Print (j)
The loop here will print out what J needs to do between 5-8, but will not terminate the second loop, do not satisfy the number between 5-8, and then loop on the following things to do

3, exit ()  exit the whole program, very good understanding
4, pass  is just a placeholder, what do not do
