Creating a Project in PyCharm

  1. Open PyCharm:


    • Launch PyCharm on your computer.


  3. Create a New Project:


    • Click on "File" > "New Project."
    • Choose the project type (Python) and location.
    • Configure project interpreter (virtual environment recommended).


  5. Project Structure:


    • PyCharm will create a default project structure with a virtual environment.


  7. Coding:


    • Start coding by creating Python files or importing existing ones.

  8. Example:
  9. print("Hello Welcome to PYCHARM")
    x=input("Enter any Number: ")
    print(x)
    import os
    print(os.getcwd())
    import sys
    print(sys.platform)
    print(sys.path)
    import platform
    print(platform.python_version())
    import keyword
    print(keyword.kwlist)

    To run the code Ctrl+Shift+F10

Debugging in PyCharm

  1. Setting Breakpoints:


    • Click in the left gutter next to the line number where you want to set a breakpoint.
    • Run your code in debug mode.


  3. Debugging Session:


    • When the code hits a breakpoint, PyCharm enters debugging mode.
    • Use the debugger toolbar to step through code, inspect variables, and more.


  5. Console and Watches:


    • Use the interactive console in the debugger to run additional commands.
    • Add watches to monitor specific variables during debugging.


  8. Resume and Stop:


    • Use the debugger toolbar to resume execution or stop the debugging session.


  10. Evaluate Expressions:


    • Right-click on variables and expressions to evaluate them during debugging.

This is a high-level overview, and PyCharm has many more features and options to explore. The steps and features might vary slightly based on the specific version of PyCharm you are using.

Certainly! Below is a simple Python code snippet that you can use in PyCharm. This code defines a basic class and demonstrates the use of a few Python concepts such as class instantiation, methods, and printing

output:

# Sample Python Code in PyCharm

class Animal:
def __init__(self, name, sound):
self.name = name
self.sound = sound

def make_sound(self): return f"The {self.name} says {self.sound}!" # Instantiate objects of the Animal class cat = Animal("Cat", "Meow") dog = Animal("Dog", "Woof") # Call the make_sound method on each object cat_sound = cat.make_sound() dog_sound = dog.make_sound() # Print the output print(cat_sound)
print(dog_sound)

To run this code in PyCharm, follow these steps:

  1. Open PyCharm and create a new Python project.
  2. Inside the project, create a new Python file (e.g., sample_code.py).
  3. Copy and paste the code into the Python file.
  4. Right-click within the file editor and select "Run 'sample_code'" or use the green run button in the toolbar.

This code defines an Animal class with a constructor (__init__ method) to initialize the name and sound attributes. The class also has a make_sound method that returns a string describing the sound the animal makes. Two instances of the Animal class (cat and dog) are created, and their make_sound methods are called and printed.

Feel free to modify and experiment with the code to explore PyCharm's features, such as code completion, debugging, and more.
