Fix IndentationError in Susceptibility Predictor.py preventing Streamlit app startup

[Copilot]

Problem

The myproject/pages/Susceptibility Predictor.py file contained a critical IndentationError that prevented the Streamlit application from starting. The error occurred in the load_resources() function where there was missing indentation and a missing for loop.

Error Details

# Before (lines 136-146) - BROKEN:
        # Check if files exist
            missing_files = []  # ← Incorrect indentation
        file_paths = [
            (model_path, "EarthquakePredictor.pkl"),
            (scaler_fd_path, "fault_density_scaler.pkl"),
            (scaler_hd_path, "hubdist_scaler.pkl"),
            (scaler_mag_path, "mag_scaler.pkl"),
            (data_path, "EarthquakeFeatures.csv")
        ]
            if not os.path.exists(path):  # ← Missing for loop, incorrect indentation
                missing_files.append(name)

This caused a Python IndentationError: unexpected indent on line 136, preventing the app from running entirely.

Solution

Fixed the indentation and added the missing for loop to properly iterate through file paths:

# After (lines 136-147) - FIXED:
        # Check if files exist
        missing_files = []
        file_paths = [
            (model_path, "EarthquakePredictor.pkl"),
            (scaler_fd_path, "fault_density_scaler.pkl"),
            (scaler_hd_path, "hubdist_scaler.pkl"),
            (scaler_mag_path, "mag_scaler.pkl"),
            (data_path, "EarthquakeFeatures.csv")
        ]
        
        for path, name in file_paths:
            if not os.path.exists(path):
                missing_files.append(name)

Changes Made

• Line 136: Fixed indentation of missing_files = [] (removed extra 4 spaces)
• Line 145: Added missing for path, name in file_paths: loop
• Lines 146-147: Existing if statement and append call are now properly indented within the for loop

Impact

• ✅ Critical Fix: Application can now start successfully
• ✅ Syntax Valid: Python syntax check passes
• ✅ Streamlit Ready: streamlit run works without errors
• ✅ Minimal Changes: Only 3 lines modified, no functional logic changed

Verification

• Confirmed with python -m py_compile - no syntax errors
• Verified with streamlit run - app starts successfully
• Tested AST parsing - file is valid Python code

The Susceptibility Predictor page is now accessible without syntax errors and the application can run as intended.

Problem Description

The myproject/pages/Susceptibility Predictor.py file contains a critical IndentationError that prevents the Streamlit application from running. The error occurs in the load_resources() function where there is missing indentation and a missing for loop.

Current Problematic Code (lines 136-146)

        # Check if files exist
            missing_files = []  # ← Incorrect indentation
        file_paths = [
            (model_path, "EarthquakePredictor.pkl"),
            (scaler_fd_path, "fault_density_scaler.pkl"),
            (scaler_hd_path, "hubdist_scaler.pkl"),
            (scaler_mag_path, "mag_scaler.pkl"),
            (data_path, "EarthquakeFeatures.csv")
        ]
            if not os.path.exists(path):  # ← Missing for loop, incorrect indentation
                missing_files.append(name)

Required Fix

The code needs proper indentation and a missing for loop to iterate through the file paths:

        # Check if files exist
        missing_files = []
        file_paths = [
            (model_path, "EarthquakePredictor.pkl"),
            (scaler_fd_path, "fault_density_scaler.pkl"),
            (scaler_hd_path, "hubdist_scaler.pkl"),
            (scaler_mag_path, "mag_scaler.pkl"),
            (data_path, "EarthquakeFeatures.csv")
        ]
        
        for path, name in file_paths:
            if not os.path.exists(path):
                missing_files.append(name)

Impact

• Critical Priority: This error prevents the entire Streamlit application from running
• Status: Blocking - application cannot start until fixed
• Error Type: IndentationError causing AST parsing failure

Files to Modify

• myproject/pages/Susceptibility Predictor.py (lines 136-146)

Expected Behavior

After the fix, the application should load successfully and the Susceptibility Predictor page should be accessible without syntax errors.
