python UNIVERSAL_CODE_VALIDATOR_V3.py-
Put your Python files in a folder
/storage/emulated/0/MyPythonProjects/ ├── script1.py ├── script2.py └── UNIVERSAL_CODE_VALIDATOR_V3.py -
Navigate to that folder (in Termux)
cd /storage/emulated/0/MyPythonProjects -
Run the validator
python UNIVERSAL_CODE_VALIDATOR_V3.py
-
Choose what to scan
Enter file or directory path (or '.' for current): .- Type
.→ Scans all Python files in current folder - Type
script1.py→ Scans only that file - Leave blank → Same as
.(scans current folder)

- Console output shows summary
- HTML report saved in same folder
- JSON report also generated
Method 1: File Manager
- Open your file manager
- Navigate to the folder
- Tap on
code_analysis_YYYYMMDD_HHMMSS.html - Choose your browser to open it
Method 2: Termux (using termux-open)
# Install termux-api (if not installed)
pkg install termux-api
# Open HTML in browser
termux-open code_analysis_*.htmlMethod 3: Pydroid 3
- In Pydroid file browser

- Choose your browser
# Grant storage permission
termux-setup-storage
# Access your phone's storage
cd ~/storage/downloads # Downloads folder
cd ~/storage/dcim # Camera photos
cd ~/storage/shared # Shared storageAdd this to ~/.bashrc:
alias validate='python ~/storage/downloads/UNIVERSAL_CODE_VALIDATOR_V3.py'Then you can just type:
validate# Scan project 1
cd /storage/emulated/0/Project1
python path/to/UNIVERSAL_CODE_VALIDATOR_V3.py .
# Scan project 2
cd /storage/emulated/0/Project2
python path/to/UNIVERSAL_CODE_VALIDATOR_V3.py .Create a check_all.sh:
#!/bin/bash
for dir in /storage/emulated/0/MyProjects/*/; do
echo "Analyzing $dir"
cd "$dir"
python /path/to/UNIVERSAL_CODE_VALIDATOR_V3.py .
done# In Termux
termux-setup-storage
# Tap "Allow" when prompted- Make sure Pydroid 3 is fully installed
- Try reinstalling from Play Store
# Check current directory
pwd
# List files
ls -la
# Navigate to correct folder
cd /storage/emulated/0/YourFolder- Make sure you have a browser installed
- Try downloading a different file manager
- Copy HTML content to an online HTML viewer
- This is normal for complex codebases
- Android devices may take longer than desktops
- Consider analyzing smaller chunks
/storage/emulated/0/ → Main storage
/storage/emulated/0/Download/ → Downloads
/storage/emulated/0/Documents/ → Documents
/storage/emulated/0/DCIM/ → Camera
/data/user/0/ru.iiec.pydroid3/ → Pydroid 3 internal
~/storage/ → Termux storage shortcuts
# Create a test file first
echo 'print("Hello")' > test.py
# Analyze it
python UNIVERSAL_CODE_VALIDATOR_V3.py test.py- Week 1: Analyze simple scripts
- Week 2: Fix HIGH priority issues
- Week 3: Improve maintainability scores
- Week 4: Tackle CRITICAL issues
# Create intentionally bad code
# bad_example.py
def very_long_function_name_that_does_too_many_things():

if True:
if True:
if True:
if True:
pass # Too much nesting!
# Run validator
python UNIVERSAL_CODE_VALIDATOR_V3.py bad_example.py
# See what issues are found
# Practice fixing them!- Keep files organized in clear folder structures
- Run validator frequently - before committing code
- Use the HTML reports for detailed analysis
- Learn from issues - read the suggestions
- Start with INFO/LOW severity issues for practice
- Progress to CRITICAL issues as you improve
