1. 100個例子
expamle1: 有四個數字:1、2、3、4,能組成多少個互不相同且無重複數字的三位數?各是多少?
我的程式碼:
num={1,2,3,4} for i in num: bnum=list(num) bnum.remove(i) for b in bnum: cnum=list(bnum) cnum.remove(b) for c in cnum: print i,b,c
官方程式碼:
for i in range(1,5): for j inrange(1,5): for k in range(1,5): if( i != k ) and (i != j) and (j != k): print i,j,k
總結:
可以使用range與判斷
expamle2:企業發放的獎金根據利潤提成。利潤(I)低於或等於10萬元時,獎金可提10%;利潤高於10萬元,低於20萬元時,低於10萬元的部分按10%提成,高於10萬元的部分,可提成7.5%;20萬到40萬之間時,高於20萬元的部分,可提成5%;40萬到60萬之間時高於40萬元的部分,可提成3%;60萬到100萬之間時,高於60萬元的部分,可提成1.5%,高於100萬元時,超過100萬元的部分按1%提成,從鍵盤輸入當月利潤I,求應發放獎金總數?
我的程式碼:
I=raw_input("please input i:") I=int(I) print I bonus=0 if(I<=100000): bonus=I*0.1 elif(I<200000): bonus=100000*0.1+(I-100000)*0.075 elif(I<400000): bonus = 100000 * 0.1 + 100000 * 0.075+200000*0.05 elif(I<600000): bonus = 100000 * 0.1 + 100000 * 0.075 + 200000 * 0.05+200000*0.03 elif (I < 1000000): bonus = 100000 * 0.1 + 100000 * 0.075 + 200000 * 0.05 + 200000 * 0.03+400000*0.015 else: bonus = 100000 * 0.1 + 100000 * 0.075 + 200000 * 0.05 + 200000 * 0.03+400000*0.015+(I-1000000)*0.01 print bonus
官方程式碼
i = int(raw_input('淨利潤:')) arr = [1000000,600000,400000,200000,100000,0] rat = [0.01,0.015,0.03,0.05,0.075,0.1] r = 0 for idx in range(0,6): if i>arr[idx]: r+=(i-arr[idx])*rat[idx] print (i-arr[idx])*rat[idx] i=arr[idx] print r
example3:輸入某年某月某日,判斷這一天是這一年的第幾天?
MonthArray=[31,28,31,30,31,30,31,31,30,31,30,31] date=raw_input("please input the date:") datearray=date.split("-") year=datearray[0] month=datearray[1] day=datearray[2] result=0 if (int(month)>1): for i in range(int(month)-1): result=result+MonthArray[i] result=result+int(day) if(int(year)%4==0): result=result+1 else: result=day print result
官方程式碼:
year = int(raw_input('year:\n')) month = int(raw_input('month:\n')) day = int(raw_input('day:\n')) months = (0,31,59,90,120,151,181,212,243,273,304,334) if 0 < month <= 12: sum = months[month - 1] else: print 'data error' sum += day leap = 0 if (year % 400 == 0) or ((year % 4 == 0) and (year % 100 != 0)): leap = 1 if (leap == 1) and (month > 2): sum += 1 print 'it is the %dth day.' % sum
example4:輸入三個整數x,y,z,請把這三個數由小到大輸出
我的程式碼:
x=int(raw_input("x=")) y=int(raw_input("y=")) z=int(raw_input("z=")) array=[x,y,z] test=sorted(array) print test
官方程式碼:
l = [] for i in range(3): x = int(raw_input('integer:\n')) l.append(x) l.sort() print l
