实验1 python开发环境使用和编程初体验

#task1_1.py
print('hey, u')

print('hey', ' u')
x,y,z = 1,2,3
print(x, y, z)
print('x = %d, y = %d, z = %d' %(x,y,z))
print('x = {}, y = {}, z = {}'.format(x,y,z))
print(f'x = {x}, y = {y}, z = {z}')
print(x)
print(y)
print(z)
print(x, end=' ')
print(y, end=' ')
print(z)

　　运行结果：

#task1_2.py

x1, y1 = 1.2, 3.57
x2, y2 = 2.26, 8.7
print('{:-^40}'.format('输出1')) 
print('x1 = {}, y1 = {}'.format(x1, y1))
print('x2 = {}, y2 = {}'.format(x2, y2))
print('{:-^40}'.format('输出2'))
print('x1 = {:.1f}, y1 = {:.1f}'.format(x1, y1))
print('x2 = {:.1f}, y2 = {:.1f}'.format(x2, y2))
print('{:-^40}'.format('输出3'))
print('x1 = {:<15.1f}, y1 = {:<15.1f}'.format(x1, y1))
print('x2 = {:<15.1f}, y2 = {:<15.1f}'.format(x2, y2))

print('x2 = {:>15.1f}, y2 = {:>15.1f}'.format(x2, y2))

　　运行结果：

#task1_3.py
name1, age1 = 'Bill', 19
name2, age2 = 'Hellen', 18
title = 'Personnel Information'
print(f'{title:=^40}')
print(f'name: {name1:10} age: {age1:3}')
print(f'name: {name2:10} age: {age2:3}')
