In Python, you can create a patch file using the built-in difflib module. The difflib module provides a unified_diff function that generates a patch file in the unified diff format. Here\’s an example:
import difflib
# Define the original and modified text
original_text = \’Hello, World!\’
modified_text = \’Hello, Python!\’
# Generate the patch file
diff = difflib.unified_diff(original_text.splitlines(), modified_text.splitlines(), lineterm=\’\’)
# Write the patch file to disk
with open(\’my_patch.patch\’, \’w\’) as patch_file:
patch_file.write(\’\\n\’.join(diff))
In this example, the unified_diff function takes two sequences of lines (in this case, the original and modified text split into lines) and generates a unified diff object. The lineterm argument specifies the line ending character to use in the output.
Finally, the patch file is written to disk using a with statement to automatically close the file after writing. The join method is used to concatenate the lines of the diff object into a single string, which is then written to the file.
