Banker's algorithm implementation in Python

The algorithm (find_safe_sequence() function) for finding the safe sequence:

1. Make a loop while the length of safe_seq_list is not equal to the no_of_job,
2. Inside the loop, make a for loop, so as to access keys (job_name) and values (need_list) over each iteration,
3. Make a flag (initialize it as True which means it resource needed is less than available CPU resources) for checking whether the resources is lesser or greater than available CPU resources.
4. Make another for loop, just to make sure the process (job_name) is not already in the safe_seq_list,
5. Check for the resources needed and available CPU available conditions if satisfy, pass it else make the flag = False
6. Outside for loop, check for flag status, if it is True , append the process (job_name) to the safe_seq_list. Update (new_cpu_available) the new CPU resources by adding the current process resources and available CPU resources. Also, delete the process (job_name) from the res_need_dict_copy dictionary, as the process is safe and has been added to the safe_seq_list.
7. Finally, outside while loop, print the safe sequence.
8. Run the above, recursively, till the safe_seq_list is equal to the no_of_jobs.

Test case:

Run the program using: python3 bankers.py
CPU Resources:
Available: 2 1 0

Number of jobs: 5
Enter currentlly allocated resources for P0: 1 1 2
Enter currentlly allocated resources for P1: 2 1 2
Enter currentlly allocated resources for P2: 4 0 1
Enter currentlly allocated resources for P3: 0 2 0
Enter currentlly allocated resources for P4: 1 1 2

Current resources dict: {'P0': [1, 1, 2], 'P1': [2, 1, 2], 'P2': [4, 0, 1], 'P3': [0, 2, 0], 'P4': [1, 1, 2]}

Enter max resource for P0: 4 3 3
Enter max resource for P1: 3 2 2
Enter max resource for P2: 9 0 2
Enter max resource for P3: 7 5 3
Enter max resource for P4: 1 1 2

Resources needed dict: {'P0': [3, 2, 1], 'P1': [1, 1, 0], 'P2': [5, 0, 1], 'P3': [7, 3, 3], 'P4': [0, 0, 0]}

No safe sequence found!
New safe seq. added: ['P1']
No safe sequence found!
No safe sequence found!
New safe seq. added: ['P1', 'P4']
New safe seq. added: ['P1', 'P4', 'P0']
New safe seq. added: ['P1', 'P4', 'P0', 'P2']
New safe seq. added: ['P1', 'P4', 'P0', 'P2', 'P3']

Safe sequence: ['P1', 'P4', 'P0', 'P2', 'P3']
