1, break: out of the loop, no longer perform
For use in the while loop and
to terminate the loop statements, i.e., no loop condition or False Condition recursive sequence has not been fully completed, will stop the execution loop
if a nested loop, break statement stops execution of the innermost loop, and start the next line of code
2, continue: out of this cycle, the next execution time
For use in the while loop and
to skip the remaining statements in the current cycle, and then continue to the next cycle of
the cycle time to this point, perform certain operations continue here, after the expiry performed, this continues to meet the conditions layer cycle needs to be done, this layer does not terminate the cycle (just out of this one).continue statement to jump out of this cycle, and break out of the cycle.
3, exit (): End / Quit the entire program
for element in "Python":
if element == "t":
exit()
else:
print(element)
#输出:Py
4, pass: can be understood as "program by" do nothing, only play the role of placeholder
for element in "Python":
if element == "y":
pass
else:
print(element)
#输出:Pthon
Learning to finish: Python in the break, continue, exit (), pass terminate difference cycle
