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。
