[Solved] Money Transfer Abstract Class Problem with Python

Money Transfer Abstract Class: Create an abstract class FundTransfer with the following methods,

Note:

Create another class NEFTTransfer with the following methods:

Note: NEFTTransfer class inherits the FundTransfer class.  

Create another class IMPSTransfer with the following method,

Note: IMPSTransfer class inherits the FundTransfer class.  

Create another class RTGSTransfer with the following method,

Note: RTGSTransfer class inherits the FundTransfer class.  

In the main section, get the values of total amount type from the user. Based on the transfer type, call the corresponding class and display the corresponding output.

Note: If choice not matches with any transfer type, then print “Wrong Transfer Type“.
Note: If the transfer amount is bigger than the balance in the account, then print “Sorry!! Not Sufficient Balance“.

Note : If validate() method returns 1,then perform corresponding operation according to the selected transfer type. If validate() method returns 0, then print “Invalid Input“.

All text in bold corresponds to the input and the rest corresponds to output.

Sample Input and Output 1

Enter the Total Amount:
20000  
1.NEFT Transfer  
2.IMPS Transfer  
3.RTGS Transfer  
Enter your choice:  
1  
Enter the account number  
8672237473  
Enter the amount to be transfer  
8000  
Your Balance:11950

  Sample Input and Output 2

Enter the Total Amount:  
15000  
1.NEFT Transfer  
2.IMPS Transfer  
3.RTGS Transfer  
Enter your choice:  
2  
Enter the account number  
9876456783  
Enter the amount to be transfer  
16000  
Sorry!! Not Sufficient Balance

Sample Input and Output 3 

Enter the Total Amount:
20000  
1.NEFT Transfer  
2.IMPS Transfer  
3.RTGS Transfer  
Enter your choice:  
3  
Enter the account number
