# @DESC    : while语句

'''
简单的while循环
'''
number=0
while number<5:
    print('当前i的值为：%i'%number)
    number=number+1

print(' = '*15)

'''
利用while循环从1累加至100
'''
index=1
total=0
while index<=100:
    total= total + index
    index= index + 1
print('0累加到100的结果是：total=%i'%total)

print(' = '*15)

'''
利用while循环打印*形图形
请注意：在调用print()时，end=''表示不换行
'''
j=0
while j<5:
    i=0
    while i<=j:
        print('*',end='')
        i=i+1
    print()
    j=j+1

print(' = '*15)

输出结果如下：

当前i的值为：0
当前i的值为：1
当前i的值为：2
当前i的值为：3
当前i的值为：4
 =  =  =  =  =  =  =  =  =  =  =  =  =  =  = 
0累加到100的结果是：total=5050
 =  =  =  =  =  =  =  =  =  =  =  =  =  =  =
