我创建了一个Python脚本，用于构建日历（.xlsx文件），并指派人员重写和改革我的大学教授的课程。
然而，代码相当“罗嗦”，而且几乎可以肯定，没有优化。我该怎么办？你有什么建议（包括我可以阅读的任何文字以增加我的知识）吗？
这是我的剧本：

#use xlsxwriter functions to initializate\create .xlsx file
workbook = xlsxwriter.Workbook('test.xlsx')
worksheet = workbook.add_worksheet()

settimana = [1, 2, 3, 4 , 5] #array that defines working days
i=0
f=open('test.txt') #inside this file we have the names (one per line) of people that is going to be in the calendar
lines=f.readlines()
array = [] #void array that is going to be "the excel table"
array.append(["data", "ora", "sbobinatore", "controllore"])
