实验1_Python语法及控制结构

.课程名称Python程序设计课程类型必修课实验名称Python语法及程序控制结构实验目的：1. 掌握Python基本的语法和数据类型；2. 掌握函数定义及调用方法；3. 掌握条件控制语句if.else的用法；4. 掌握循环控制语句While、for的用法；实验内容：1. 输入一个温度值，进行转换，要求能进行摄氏温度和华氏温度之间的互转。2. 输入x,y，判断属于第几象限。3. 输入一个年份，判断是否是闰年。（能被400整除，或者能被4整除但不能被100整除）4. 定义一个函数将给定的一个成绩对应的转换成等级（A：100-85、B：84-70、C：69-60、D：59-0）5. 完成7.1、7.3、7.5、7.6、7.7、7.8、7.96. 补充：(1) 求出100以内的所有素数(2) 所有三位水仙花数(3) 求N的阶乘(4) 求出1000以内所有奇数之和(5) 打印输出fibonacii数列前20项(6) 打印九九乘法表 要求给出完整的程序和测试运行结果。温度转换t=raw_input(Please input a temprature:)if t-1=C or t-1=c: F=float(t:-1)*1.8+32.0 print The converted temprature is %.1fF%Felif t-1=F or t-1=f: C=(float(t:-1)-32.0)/1.8 print The converted temprature is %.1fC%Celse:printinput is wrong! = RESTART = Please input a temprature:32cThe converted temprature is 89.6F = RESTART = Please input a temprature:37fThe converted temprature is 2.8C = RESTART = Please input a temprature:34dinput is wrong!象限判断(x,y)=input(Please input two numbers:)if x0: if y0: a=(%d,%d)在第一象限%(x,y) else: a=(%d,%d)在第四象限%(x,y)else: if y0: a=(%d,%d)在第二象限%(x,y) else: a=(%d,%d)在第三象限%(x,y)print a = RESTART = Please input two numbers:(7,8)点(7,8)在第一象限 = RESTART = Please input two numbers:(-2,3)点(-2,3)在第二象限 = RESTART = Please input two numbers:(-34,-43)点(-34,-43)在第三象限 = RESTART = Please input two numbers:(23,-45)点(23,-45)在第四象限 闰年判断a=input(Please input a year:)if (a%400=0)or(a%4=0 and a%100!=0): print%d 是闰年%aelse:print%d 是平年%a = RESTART = Please input a year:20142014 是平年 = RESTART = Please input a year:20372037 是平年 = RESTART = Please input a year:20082008 是闰年：等级转换a=input(Please input your grade:)if a=85: print成绩：%d，等级：A%aelif a=70: print成绩：%d，等级：B%aelif a=60: print成绩：%d，等级：C%aelse: print成绩：%d，等级：D%a = RESTART = Please input your grade:67成绩：67，等级：C = RESTART = Please input your grade:87成绩：87，等级：A 7.1：def double_preceding(values): if values=: pass else: for i in range(len(values)-1,0,-1): valuesi=2*valuesi-1 values0=0 print valuesif _name_=_main_: values=2,3,4double_preceding(values) = RESTART = 0, 4, 67.3for i in range(33,50,1):print i, = RESTART = 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 497.5sum=0count=0for i in range(2,23,1): sum+=i count+=1 average=float(sum/count)print average = RESTART = 12.07.6def remove_neg(num_list): new_list= for item in num_list: if item=0: new_list.append(item) return new_listif _name_=_main_: list=1,2,3,-3,6,-1,-3,1 print remove_neg(list) = RESTART = 1, 2, 3, 6, 1 7-7 for i in range(1,8,1): for j in range(1,i+1): print T,print = RESTART = TT TT T TT T T TT T T T TT T T T T TT T T T T T T7.9i=0while i = RESTART = TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT1-100间的素数for i in range(1,101): flay=True for j in range(2,i): if i%j=0: flay=False break if flay: print i, = RESTART = 1 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97三位数的水仙花数for i in range(100,1000): a=i/100 b=i/10%10 c=i%10 if i=pow(a,3)+pow(b,3)+pow(c,3): print i, = RESTART = 153 370 371 407N的阶乘n=input(Please input n:)for i in range(1,n+1): fac=1 for j in range(i,i+1): fac=fac*j print %d的阶乘是：%d%(i,fac) = RESTART = Please input n:71的阶乘是：12的阶乘是：23的阶乘是：34的阶乘是：45的阶乘是：56的阶乘是：67的阶乘是：7 1-1000间的所有奇数的和sum=0for i in range(1,1001,2): sum+=iprint sum = RESTART = 250000 斐波那契f1=1f2=1print f1,f2,for i in range(3,21): f3=f1+f2 f1=f2 f2=f3print f3, = RESTART = 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 6765乘法表for i in range(0,10): print%4dt%i,printfor i in range(1,10): print%4dt%i, for j in range(1,i+1): print%d*%d=%dt%(i,j,i*j), print = RESTART = 0 1 2 3 4 5 6 7 8 9 11*1=1 22*1=22*2=4 33*1=33*2=63*3=9 44*1=44*2=84*3=124*4=16 55*1=55*2=105*3=155*4=205*5=25 66*1=66*2=126*3=186*4=246*5=306*6=36 77*1=77*2=147*3=217*4=287*5=357*6=427*7=49 88*1=88*2=168*3=248*4=328*5=408*6=488*7=568
