写一个程序，该程序输入一个年份，根据该年份是否是建国整十周年、建党整十周年以及是否是闰年给出不同的输出

输出样例：

2：Illegal year.

1959：Legal year、Lucky year.

1931：Legal year、Good year.

2008：Legal year、Leap year.

2011：Legal year、Common year

代码：

year = int(input())
if year <= 0:
print(‘Illegal year’)
else:
print(‘Legal year’)
if year > 1949 and (year-1949) % 10 == 0: # 建国整十周年
print(‘Lucky year’)
elif year > 1921 and (year-1921) % 10 ==0: # 建党整十周年
print(‘Good year’)
elif year % 4 == 0 and (year % 100 == 0 or year % 400 == 0 ): # 闰年
print(‘Leap year’)
else:
print(‘Common year’)
