python123 第四次作业答案_Python第四次作业——黄亦杨

设计题1：

设计一个本月份日历，输出格式如下：

要求：

1.初始化start_day，end_day两个日期

from datetime import datetime

start_day=datetime(2019,4,1)

end_day=datetime(2019,4,30)

其它时间数据生成要用datetime或date模块的方法编程实现

2.不能使用calendar模块生成

from datetime import datetime

start_day = datetime(2019, 4, 1)

end_day = datetime(2019, 4, 30)

a = end_day-start_day

amount = a.days + 1

first = start_day.isoweekday()

k = 1

count = 0

print("\t2019年4月\n")

print("星期日 星期一 星期二 星期三 星期四 星期五 星期六")

while k<=first:

k+=1

count+=1

print("\t", end="")

day = 1

while day <= amount:

print(day, end="\t")

day += 1

count += 1

if (count % 7 == 0):

print("\n")

设计题2：

1.参考“三国演义”词频统计程序，实现对红楼梦出场人物的频次统计。

2.(可选)

将红楼梦出场人物的频次统计结果用词云显示。
