python 一些练习 （初学）

'''temp =input("请输入一个整数：")
number = int(temp)

while number :
    i = number -1
    while i :
        print('',end="")
        i =i -1
    j = number
    while j:
        print('*',end="")
    
        j = j - 1
    print()
    number = number -1'''

############    
'''i= 0
while i <=100:
    if i % 2 !=0:
        print(i,end=" ")
        i = i+1
    else:
        i = i +1'''
        
############ 成绩分类

'''def fun(x):
    if x < 60 :
        print("成绩为：D")
    elif 60<= x <80:
        print("成绩为：C")
    elif 80 <= x < 90:
        print("成绩为：B")
    else:
        print("成绩为：A")
        
score = int(input("请输入成绩："))
fun(score)'''

# 求水仙花数
'''x=1

z=0
def fun(number):
    while 100<= number<=999:
        z=number%10
        y=(number//10)%10
        x=number//100
        if number==x**3+y**3+z**3:

############# 输入密码

'''count = 3
