这个程序如何用Python 语言编写

Write a program that categorizes each mail message by which day of the week the commit was done. To do this look for lines that start with “From”, then look for the third word and keep a running count of each of the days of the week. At the end of the program print out the contents of your dictionary (order does not matter).

麻烦给出一个完整的程序

file = input("name: ")
with open(file,"r") as f:
    read = f.readlines()
read = [i.split() for i in read]
reee = []

for i in read:
    if i[0] == "From":
        reee.append(i)

dic = {}

for i in reee:
    if i[2] == "Mon":
        dic[i[2]] = dic.get(i[2],0)+1
    if i[2] == "Tue":
        dic[i[2]] = dic.get(i[2],0)+1
    if i[2] == "Wed":
        dic[i[2]] = dic.get(i[2],0)+1
    if i[2] == "Thu":
        dic[i[2]] = dic.get(i[2],0)+1
    if i[2] == "Fri":
        dic[i[2]] = dic.get(i[2],0)+1
    if i[2] == "Sat":
        dic[i[2]] = dic.get(i[2],0)+1
    if i[2] == "Sun":
        dic[i[2]] = dic.get(i[2],0)+1
print(dic)

dirname=r'C:\Users\Administrator\Desktop'

from collections import Counter

with open(dirname + "/xx.txt", encoding = 'utf-8') as f:
    lines =[i.split()[2] for i in f.readlines() if i.startswith('From')]
    d = dict(Counter(lines))
    print(d)

filename = input("Enter a file name:")
with open(dirname + "/" + filename, 'w', encoding = 'utf-8') as f:
    f.write(str(d))
