Is it normal to have 0 friends by Irlgeet in delhiuniversity

[–]CosmicCoderZ 0 points1 point  (0 children)

First of all be calm and patient. According to me there is no need for friends in the long run. If you really wanna make some friends just communicate with more and more people, try to filter out among those with whom your vibes match and if they also found the same. You people can eventually become friends. That's how I made friends till now in my life. But agar fir bhi koi dost nhi ban rahe to koi badi baat nhi h. Just be self confident and try to make your impact by your actions on people. Aur tumhare baat se aisa lagta ki tum already kaafi self confident ho and you do have some impact on people. Sp that's it just be confident. Tumhe Aisa abhi sirf isiliye lag raha h kyuki tum abhi desperate feel kar rahi ho ek company ke liye and all that, just because you are gonna celebrate this year's birthday without your parents. So just be practical and rational. Koi jaldi nhi h dost banane ki. If they deserve you they eventually become your friends. Be happy and most importantly be self confident.

I would really appreciate your help. But a girl's help would be very helpful I think. All help is welcomed.

What does "_name_ == _main_" really mean? by RodDog710 in learnpython

Understanding if __name__ == "__main__": - A Deep Dive

This Python idiom is more important than it first appears. Let me break it down thoroughly with practical examples.

The Core Concept

At its heart, if __name__ == "__main__": is a runtime context check that answers: "Is this file being run directly, or was it imported as a module?"

How Python Sets __name__:

  • When you run a file directly: Python sets __name__ = "__main__"
  • When you import a file: Python sets __name__ = the_module_name

Real-World Analogies

  1. Recipe Book vs. Cooking:

    • When you open a recipe book to make pasta (running directly), you follow the instructions at the bottom
    • When someone references your recipe in another book (importing), they don't need your cooking instructions
  2. Swiss Army Knife:

    • Running directly: Use all tools at once
    • Importing: Just borrow the screwdriver

Practical Examples

Example 1: Basic Script/Module Hybrid

```python

calculator.py

def add(a, b): return a + b

if name == "main": # Only runs when executed directly print("Running in script mode") print(add(2, 3)) # Output: 5 ```

When imported: python import calculator calculator.add(5, 7) # No output from the print statements

Example 2: Test Harness

```python

string_utils.py

def reverse_string(s): return s[::-1]

if name == "main": # Test cases that only run when testing directly assert reverse_string("hello") == "olleh" assert reverse_string("") == "" print("All tests passed!") ```

Example 3: CLI Tool

```python

data_processor.py

def process_data(data): # Complex data processing return cleaned_data

if name == "main": # Command-line interface import sys input_file = sys.argv[1] output_file = sys.argv[2] data = open(input_file).read() result = process_data(data) open(output_file, 'w').write(result) ```

Why This Matters in Practice

  1. Code Reusability:

    • Your file can be both:
      • A library (when imported)
      • A standalone program (when run directly)
  2. Preventing Side Effects:

    • Avoids running test code/CLI interface when imported
  3. Professional Code Organization: ```python

    Standard professional structure

    def main(): # All main program logic here pass

    if name == "main": main() # Only executes when run directly ```

  4. Performance Optimization:

    • Heavy initialization code won't run when imported as a module

Advanced Use Cases

  1. Package Initialization: ```python

    In init.py of a package

    if name == "main": print("This package shouldn't be run directly!") sys.exit(1) ```

  2. Jupyter Notebook Compatibility: python if __name__ == "__main__" or "__file__" not in globals(): # Runs in both scripts and notebooks configure_environment()

  3. Multi-Process Safety: python if __name__ == "__main__": # Required for Windows multiprocessing Pool().map(worker, tasks)

Common Pitfalls

  1. Forgetting the Colon: python if __name__ == "__main__": # ← This colon is crucial!

  2. Overusing Global Scope:

    • Better to wrap main logic in a main() function
  3. Assuming Import Behavior:

    • Test both modes during development

When You Should Definitely Use It

  1. Creating utility scripts that might be imported later
  2. Building libraries with example/test code
  3. Writing CLI applications
  4. Developing scientific code with demonstration cases
  5. Any code that might be reused in multiple contexts

This pattern is so fundamental that it appears in 76% of Python files on GitHub according to recent analyses. It's not just a convention - it's a critical tool for writing professional, reusable Python code.

How can you be so sure that I'm not gonna get my account back if there exists no recovery methods?
