The complete definition of a program is as follows:

Write a program to accept transaction details in dictionary form and display updated balance.

So as per the questions given, we need the following variables:

2. A dictionary accepts the transaction details where transaction type (D for Debit and C for Credit) as a key and amount as a value
3. i for traversing a dictionary in for loop

Steps

1. Declare a variable for initial balance. In our program its bal = 50000
2. Print the initial balance
3. Prompt for transaction detail using eval(inut())
4. Take a for loop to traverse a dictionary
5. Now apply if condition for the appropriate function as per the transaction
6. Check the key, if it is ‘D’ deduct value from bal
7. If the key is ‘C’ add the value into bal
8. Print the updated closing balance

Code

Observe the code for the program:

'''Write a program to accept transaction details
in dictionary form and display balance.'''
#For example:
#Enter transaction:{'D':5000}
#Output should be:
'''Initial Balance - 50000
Closing Balance after transaction - 45000'''

#Step 1 Initiate Balance
bal=50000

#Input transaction details
tr=eval(input("Enter transaction detail:"))

#Printing Initial Balance
print("Initial Balance - ",bal)

#Traversing Dictionary to perform the transaction
for i in tr:
  #Checking if transaction for debit and update balance
  if i=='D':
    #Update balance
    bal-=tr[i]
  #Checking if transaction for credit and update balance
  if i=='C':
    bal+=tr[i]
