Python流程控制（Python流程控制语句有哪些）

Python流程控制

1、if条件选择

# coding:utf-8# Time:2022/6/28 20:57# Author:Yang Xiaopengnum = 23if num>2: print("dayu")if num<2: print("xiaoyu")## if elseif num>10: print("D")else: print("A")## if elif elseif num < 10: print("D")elif num < 20: print("C")elif num < 30: print("B")else: print("A")## if 嵌套if num > 10: if num>20: if num >30: print("A") else: print("B") else: print("C")else: print("D")

2、for循环

# coding:utf-8# Time:2022/6/28 20:57# Author:Yang Xiaopengfor i in (1,2,3,4,5,6,7,8): if i < 8: print(i,end="____") else: print(i)list1 = [1,2,3,4,5,6]for item in list1: if item / 2 == 1: print(item)for item in "asjhlafjhkllsadk": if item == 'k': print(item) else: print(item,end="_")

3、while循环

# coding:utf-8# Time:2022/6/28 20:57# Author:Yang Xiaopeng# 死循环"""while True: pass"""num = 1while num<10: print(num,end="_") num+=1

4、break 及 continue

break: 结束循环continue 退出本轮循环，继续下一轮循环

# coding:utf-8# Time:2022/6/28 20:57# Author:Yang Xiaopengnum = 0while num<10: num += 1 if num <=6: continue print(num, end="_")print("")num =0while num<10: num = num + 1 if num == 6: break print(num, end="_")
