条件分支和循环结构

#for循环（可迭代）
for a in range(1,10):
for b in range(1,a+1):
print(b,'*',a,'=',b*a)
print()

#while循环，需要指定条件
c=0
while c<9:
c=c+1
d=0
while c>d:
d=d+1
print(d,'×',c,'=',d*c,'\t')
print('\n')

#continue结束本次循环
for e in range(15):
if e == 10:
continue
print(e)

#break结束循环体
f=0
while f<10:
f=f+1
if f==6:
break
print(f)

#循环判断结束
for a in range(3):
password = int (input('请输入数字密码：'))
if password == int('123456'):
print('密码正确')
break
else:
print('密码错误')
a+=1
