实验任务1: task1_2.py 1 x1, y1 = 1.2, 3.57 2 x2, y2 = 2.26, 8.7 3 print('{:-^40}'.format('输出1')) 4 print('x1 = {}, y1 = {}'.format(x1, y1)) 5 print('x2 = {}, y2 = {}'.format(x2, y2)) 6 print('{:-^40}'.format('输出2')) 7 print('x1 = {:.1f}, y1 = {:.1f}'.format(x1, y1)) 8 print('x2 = {:.1f}, y2 = {:.1f}'.format(x2, y2)) 9 print('{:-^40}'.format('输出3')) 10 print('x1 = {:<15.1f}, y1 = {:<15.1f}'.format(x1, y1)) 11 print('x2 = {:<15.1f}, y2 = {:<15.1f}'.format(x2, y2)) 12 print('{:-^40}'.format('输出3')) 13 print('x1 = {:>15.1f}, y1 = {:>15.1f}'.format(x1, y1)) 14 print('x2 = {:>15.1f}, y2 = {:>15.1f}'.format(x2, y2))
实验任务1: task1_3.py: 1 name1, age1 = 'Bill', 19 2 name2, age2 = 'Hellen', 18 3 title = 'Personnel Information' 4 print(f'{title:=^40}') 5 print(f'name: {name1:10}, age: {age1:3}') 6 print(f'name: {name2:10}, age: {age2:3}') 7 print(40*'=') print()用于输出的几种常用用法:1、输出字符串,使用单引号或双引号; 2、数字,直接输出即可; 3、print()输出后会自动换行,用英文逗号隔开可以不换行。
实验任务2: task2_1.py: r1 = eval('1 + 2') print(type(r1), r1) r2 = eval('[1, 6, 7.5]') print(type(r2), r2) r3 = eval('"python"') print(type(r3), r3) r4 = eval('7, 42') print(type(r4), r4)
实验任务2: task2_2.py: x, y = eval(input('Enter two oprands: ')) ans = x + y print(f'{x} + {y} = {ans}') print(f'{type(x)} + {type(y)} = {type(ans)}')
实验任务3: task3.py: 1 ans1 = 0.1 + 0.2 2 print(f'0.1 + 0.2 = {ans1}') 3 from decimal import Decimal 4 ans2 = Decimal('0.1') + Decimal('0.2') 5 print(f'0.1 + 0.2 = {ans2}')
实验任务4: task4.py: 1 print(chr(0x1f600), end = " ") 2 print(chr(0x1f601), end = " ") 3 print(chr(0x1f602), end = " ") 4 print(chr(0x1f603), end = " ") 5 print(chr(0x1f604)) 6 print(chr(10000), end=" ") 7 print(chr(0x025b), end=" ") 8 print(chr(0x2708), end=" ") 9 print(chr(0x00A5), end=" ") 10 print(chr(0x266b)) 11 print(ord('a'), end = " ") 12 print(ord('b'), end = " ") 13 print(ord('c')) 14 print(ord('A'), end = " ") 15 print(ord('B'), end = " ") 16 print(ord('C')) 17 print(ord('0'), end = " ") 18 print(ord('1'), end = " ") 19 print(ord('2'))
实验任务5: task5_1.py: 1 from math import sqrt 2 n = float(input('输入一个数:')) 3 ans1 = sqrt(n) 4 ans2 = n**0.5 5 print('%.2f的平方根是: %.2f' %(n, ans1)) 6 print('{:.2f}的平方根是: {:.2f}'.format(n, ans2)) 7 print(f'{n:.2f}的平方根是: {ans2:.2f}')
实验任务5: task5_2.py: 1 from math import pi 2 text=''' 3 好奇心是人的天性。 4 理想情况下,学习新东西是让人愉快的事。 5 但学校里的学习似乎有点像苦役。 6 有时候,需要画一个大饼,每次尝试学一些新鲜的,才会每天变得更好一点点。 7 ''' 8 print(text) 9 r=float(input('给学习画一个大饼,大饼要做的很大,半径要这么大:')) 10 circle=2*pi*r 11 print(f'绕起来,大饼的圆周有这么长,{circle},够不够激发你探索未知的动力...')
实验任务6: 1 x=eval(input('输入一个数x:')) 2 y=x**365 3 print('x的365次方:',y)
1 T0=eval(input('输入一个温度:')) 2 p=1.038 3 c=3.7 4 k=5.4*10**(-3) 5 M=67 6 Tw=100 7 Ty=70 8 n=0.76 9 from math import pi 10 a=pi 11 from math import log 12 t=(M**(2/3)*c*p**(1/3))/(k*a**2*(4*a/3)**(2/3))*log(n*(T0-Tw)/(Ty-Tw)) 13 print('T0=',T0,'摄氏度',',','t=',int(t/60),'分',t-60*int(t/60),'秒')
