私は問題があります。

「表示」コマンドですべてのレコードを表示したいのですが、最後のレコードしか表示されません。

どうすれば問題を解決できますか？

私を助けてください、ありがとう！

私のコード：

initial_money = int(input('How much money do you have? ')) 

def records():
    return

def add(records):
    records = input('Add an expense or income record with description and amount:\n').split()
    global rec
    rec = records[0]
    global amt
    amt = records[1]
    global initial_money
    initial_money += int(amt)
    
def view(initial_money, records):
    print("Here's your expense and income records:") 
    print("Description          Amount")
    print("-------------------  ------")
    print('{name:<20s} {number:<6s}'.format(name = rec,number = amt))
    print('Now you have {} dollars.'.format(initial_money))

while True:
    command = input('\nWhat do you want to do (add / view / delete / exit)? ') 
    if command == 'add':
        records = add(records)
    elif command == 'view':
        view(initial_money, records)

出力

How much money do you have? 100

What do you want to do (add / view / delete / exit)? add
Add an expense or income record with description and amount:
tomato -50

What do you want to do (add / view / delete / exit)? add
Add an expense or income record with description and amount:
salary 100

What do you want to do (add / view / delete / exit)? view
Here's your expense and income records:
Description          Amount
-------------------  ------
salary               100   
Now you have 150 dollars.

私が欲しい出力：

-------------------  ------
tomato               -50
salary               100
Now you have 150 dollars.

代わりに、辞書を使用してそれらを保持します。

initial_money = int(input('How much money do you have? ')) 

mr = {}

def records():
    return

def add(records):
    records = input('Add an expense or income record with description and amount:\n').split()
    global rec
    rec = records[0]
    global amt
    amt = records[1]
    global mr
    global initial_money
    mr[rec] = int(amt)
    initial_money += mr[rec]
    
    
def view(initial_money, records):
    print("Here's your expense and income records:") 
    print("Description          Amount")
    print("-------------------  ------")
    for r,a in mr.items():
      print('{name:<20s} {number:<6s}'.format(name = r,number = str(a)))

    print('Now you have {} dollars.'.format(initial_money))

while True:
    command = input('\nWhat do you want to do (add / view / delete / exit)? ') 
    if command == 'add':
        records = add(records)
    elif command == 'view':
        view(initial_money, records)
