怎么用python command记录预定信息呢？

Question

如果要用python写一个餐桌预定系统，客人会input包括名字、电话号码、预定日期和预订人数。
我用command.split把它们分隔开，然后想记录并编码这些预订信息，可以怎么样呢？
我想要的output如下！谢谢！

Answer 1

file = input()
with open(file,'r') as f:
    lines = f.readlines()
    nums = len([line for line in lines if len(line.strip())==2])
    #print(f"Table file:\ntablefile.txt")
    print(f'Imported {nums} table(s)')
    f.close()
orders = {}
while True:
    order = input()
    if(order=='Exit'):
        break
    else:
        date = order.split('|')[3]
        if date in orders.keys():
            orders[date] = orders[date]+1
        else:
            orders[date] = 1
        print(f'Added booking. The ticket code for {date} is {orders[date]}')
print('Bye')
