+
+I'll modify the script to use `argparse` for handling command-line arguments. This will allow you to pass the file path directly when running the script:
+
+```python
+import xml.etree.ElementTree as ET
+import re
+import argparse
+
+def extract_look_tags(xml_file):
+    # Read the XML file content
+    with open(xml_file, 'r') as file:
+        xml_content = file.read()
+    
+    # Find all <c:look> tags using regex
+    pattern = r'<c:look>(\d+)</c:look>'
+    matches = re.findall(pattern, xml_content)
+    
+    # Print the numbers
+    for number in matches:
+        print(number)
+
+def main():
+    # Set up argument parser
+    parser = argparse.ArgumentParser(description='Extract numbers from <c:look> tags in an XML file')
+    parser.add_argument('file_path', help='Path to the XML file')
+    
+    # Parse arguments
+    args = parser.parse_args()
+    
+    # Process the file
+    extract_look_tags(args.file_path)
+
+if __name__ == "__main__":
+    main()
+
+```
+
+Now you can run the script from the command line like this:
+
+```
+python script_name.py path/to/your/xml_file.xml
+```
+
+The script will:
+1. Use `argparse` to handle the command-line argument for the file path
+2. Parse the XML file to find all `<c:look>` tags
+3. Extract and print the numbers inside these tags
+
+This approach makes the script more user-friendly and suitable for scripting or batch processing.
