python 输入总费用和聚餐人员，计算人均费用

save.py

def savetofile(memberlist, avgfee):
    with open(‘record.txt‘,‘a‘,encoding=‘utf8‘) as f:
        recordlist = [f‘{member}:{avgfee}‘ for member in memberlist]
        f.write(‘ | ‘.join(recordlist)+‘\n‘)
aa.py

from save import savetofile
fee = input(‘请输入午餐费用：‘)
members = input(‘请输入聚餐人姓名，以英文逗号,分隔：‘)
# 将人员放入一个列表
memberlist = members.split(‘,‘)
# 得到人数
headcount = len(memberlist)
# 计算人均费用
avgfee = int(fee)/headcount
print(avgfee)
savetofile(memberlist,avgfee)

主要是里面含有循环的嵌套
