1#1，2，3，4，組成各不相同的三位數
for i in range(1, 5):
for j in range(1, 5):
for k in range(1, 5):
if(i != j) and (i != k) and (j != k):
s = 100i+10j+k
print(s)
print(i, j, k)
2# 企業利潤
這個思想很重要，採用數軸的方式，而不是很蠢的用if else 語句來不斷的判斷
fund = int(input(「請輸入本月的利潤輸入：」))
profit = [1000000, 600000, 400000, 200000, 100000, 0]
percent =[0.01, 0.015, 0.03, 0.05, 0.075, 0.1]
r = 0
for i in range(6):
if fund>profit[i]:
*r=r+(fund-profit[i])percent[i]
fund = profit[i]
print®
3#找出完全平方數
演算法很重要，說明了詳細的推到過程
for i in range(1, 85):
if 168 % i == 0 and i % 2 == 0:
j = 168 / i
if i > j and (i+j) % 2 == 0 and (i-j) % 2 == 0:
m = (i+j)/2
n = (i-j)/2
x = n*n - 100
print(x)
4# 判斷這一天是哪一天
monthlist = [0, 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334]
youryear = int(input(「enter your year number:」))
yourmonth = int(input(「enter your month number:」))
yourday = int(input(「enter your day number:」))
cacul = 0
1# for i in range(yourmonth - 1):
1# cacul += monthlist[i]
cacul = monthlist[yourmonth-1] + yourday
leap = 0
if (youryear % 400 == 0) or ((youryear % 4 == 0) and (youryear % 100 != 0)):
leap = 1
if (leap == 1) and (yourmonth > 2):
cacul += 1
