then can you show me how can I run this python program if I have 2 yaml files, say, 1.yaml and 2. yaml? what python commands should I use in order to print out either 1.yaml and 2.yaml are the same, or print out the difference between 1.yaml and 2. yaml? I mean I’m quite new to python

Sure, I can help you with that.

You can use the PyYAML library in Python to load and compare the contents of two YAML files. Here is some sample code to get you started:

import yaml

# Load the contents of the first YAML file
with open('1.yaml', 'r') as file:
    data1 = yaml.safe_load(file)

# Load the contents of the second YAML file
with open('2.yaml', 'r') as file:
    data2 = yaml.safe_load(file)

# Compare the two YAML files
if data1 == data2:
    print("The two YAML files are the same")
else:
    print("The two YAML files are different")

This code will load the contents of `1.yaml` and `2.yaml` into two separate variables (`data1` and `data2`), and then compare them using the `==` operator. If the two files have the same contents, it will print "The two YAML files are the same". Otherwise, it will print "The two YAML files are different".

I hope this helps! Let me know if you have any further questions.
