from requests import get
response = get("https://api.github.com") # Autocompleted
3. Debug Visually:
`
Click line number to add breakpoint
Run → Debug
Step through code, watch variables

Tips & Tricks
1. Use Type Hints: PyCharm understands them
`python``
def greet(name: str) -> str:
return f"Hello {name}" # PyCharm knows return type
2. IDE Intentions (Alt+Enter): Quick fixes, refactorings
3. Structure View: Navigate large files
4. Diagram Tools: Visualize class hierarchies
5. Database Console: Query databases directly
6. Python Console: Interactive REPL with project imports
Performance Tips
- Exclude folders from indexing (library dependencies)
- Disable unnecessary plugins
- Increase IDE memory in vmoptions
- Use SSD for project files
PyCharm is the professional choice for Python development — combining powerful features with intelligent productivity tools that help developers write better code faster, justifying its investment through time saved and quality improved.
