This is a Python script for implementing the Banker's Algorithm for resource allocation and deadlock avoidance. It was originally written in Java for my Operating Systems class, but I wanted to convert it to Python for practice.

The program asks for a filename where the format is:

resources m, processes n

total number of resource units

next n lines, resource needs for each process

next n lines, resources allocated to each process

Example:

5,7

8,6,9,5,7

1,2,1,2,1

2,0,1,0,2

0,0,1,0,1

1,2,1,2,0

2,0,1,0,1

1,1,0,1,2

2,3,2,2,1

2,1,0,1,0

0,2,3,1,1

1,0,2,0,1

1,0,1,0,1

0,0,1,0,2

1,0,0,1,1

2,3,1,2,0

This program not only finds the greedy sequence, but finds all possible safe sequences for the given values.

Sample output:
