task1-3

1 name1, age1 = 'Bill', 19
2 name2, age2 = 'Helle', 18
3 title = 'Personnel Information'
4 
5 print(f'{title:^40}')
6 print(f'name:{name1:10} age" {age1:3}')
7 print(f'name:{name2:10} age" {age2:3}')
8 print(40*'=')

实验总结

print()的常用的几种输出方式：1.用于输出单个字符串或单个变量print(' ')。2.用于输出多个数据项，用逗号隔开print(' ', ' '）
