How to print the updated output

I need help with my code because it doesn’t print the updated output

For example:

Enter First name: Cid
Enter Middle name: RAZOR
Enter Last name: Kamisato
Enter number of subjects: 1
Please enter this valid subjects: ['CC1', 'CC2', 'CC3', 'CC4', 'CC5']
Please enter the subject: cc1
**** This is your info *****
First name is: Cid
Middle name is: RAZOR
Last name is: Kamisato
Your Selected Subjects are: ['cc1']
Do you want to change anything?(Y/N): y
1. Change First name
2. Change Middle name
3. Change Last name
4. Change number of subjects & change the subjects 
5. Exit
What do you want to change?: 1
Enter First name: CID
****** This is your updated info *******
First name is: CID
Middle name is: RAZOR
Last name is: Kamisato
Number of subjects: 1
Your Selected Subjects are: ['cc1']
Do you want to change anything?(Y/N): y
1. Change First name
2. Change Middle name
3. Change Last name
4. Change number of subjects & change the subjects 
5. Exit
What do you want to change?: 2
Enter Middle name: razor
****** This is your updated info *******
This is your first name: Cid
Middle name is: razor
Last name is: Kamisato
Number of subjects: 1
Your Selected Subjects are: ['cc1']

I want the updated CID name to be printed in the updated output and so on.
