3. ? Learn Object Oriented Programming (OOP)
OOP is key in software engineering, as it allows you to organize and reuse your code. Learn:
Classes and Objects:
python
Copy code
class Person:
def init(self, name):
self.name = name
p = Person("Ana")
print(p.name)
Encapsulation: Protect attributes with _private or __very_private.
Inheritance: Extend existing classes without rewriting everything.
Polymorphism: Methods with different behaviors.
? Practical exercise: Create a Vehicle class with attributes and subclasses such as Car or Motorcycle.
4. ?? Learn to use Git and GitHub
Every software engineer must master version control.

Search and sorting algorithms: binary search, merge sort.
Data structures: lists, queues, stacks, trees and graphs.
? Daily Practice:
Solve problems in LeetCode and HackerRank.
Break down big problems into smaller solutions.
8. ? Learn about Testing and code quality
Write robust code using automated tests:
Pytest: Simple and powerful framework for testing.
Doctest: Add tests in your code documentation.
Basic test example with pytest:
def sum(a, b):
return a b
def test_sum():
assert sum(2, 3) == 5
9. ? Learn about APIs and microservices
The creation of APIs allows communication between applications.
- RESTful APIs: Use Flask or FastAPI to create routes and return data in JSON.
- API consumption: Use libraries as requests.
- ? Practical exercise: Create an API that sends weather data using external data such as OpenWeatherMap.
10. ? Build real projects and create a portfolio
Apply everything learned in practical projects:
- CRUD Application: Management of tasks, users or notes.
- Automated script: For example, a bot that checks your email.
- REST API: Publish useful data and documentation (with Swagger).
- Web Portfolio: Create a portfolio using Flask or Django.
- ? Resource: Use GitHub Pages to deploy projects and show your code.
11. ? Apply and get a job
Prepare your CV and start applying for vacancies. Practice makes perfect; little by little you will improve in the interviews.
To look for a job in the IT sector, you can use a specialized portal for IT profiles such as:
- We Work Remotely
- Getonbrd
- Hireline
- Findjobit
- Wellfound
? What's next?
Once you execute these 11 steps, consider exploring:
- Cloud development (AWS, Azure).
- DevOps and automation with Docker and CI/CD.
- Distributed systems.
? Start now and advance step by step! Each line of code brings you closer to your goal: becoming a software engineer. ?

The key to dealing with API authentication is to understand and use the authentication method correctly. 1. APIKey is the simplest authentication method, usually placed in the request header or URL parameters; 2. BasicAuth uses username and password for Base64 encoding transmission, which is suitable for internal systems; 3. OAuth2 needs to obtain the token first through client_id and client_secret, and then bring the BearerToken in the request header; 4. In order to deal with the token expiration, the token management class can be encapsulated and automatically refreshed the token; in short, selecting the appropriate method according to the document and safely storing the key information is the key.

A common method to traverse two lists simultaneously in Python is to use the zip() function, which will pair multiple lists in order and be the shortest; if the list length is inconsistent, you can use itertools.zip_longest() to be the longest and fill in the missing values; combined with enumerate(), you can get the index at the same time. 1.zip() is concise and practical, suitable for paired data iteration; 2.zip_longest() can fill in the default value when dealing with inconsistent lengths; 3.enumerate(zip()) can obtain indexes during traversal, meeting the needs of a variety of complex scenarios.

To create modern and efficient APIs using Python, FastAPI is recommended; it is based on standard Python type prompts and can automatically generate documents, with excellent performance. After installing FastAPI and ASGI server uvicorn, you can write interface code. By defining routes, writing processing functions, and returning data, APIs can be quickly built. FastAPI supports a variety of HTTP methods and provides automatically generated SwaggerUI and ReDoc documentation systems. URL parameters can be captured through path definition, while query parameters can be implemented by setting default values ??for function parameters. The rational use of Pydantic models can help improve development efficiency and accuracy.

To test the API, you need to use Python's Requests library. The steps are to install the library, send requests, verify responses, set timeouts and retry. First, install the library through pipinstallrequests; then use requests.get() or requests.post() and other methods to send GET or POST requests; then check response.status_code and response.json() to ensure that the return result is in compliance with expectations; finally, add timeout parameters to set the timeout time, and combine the retrying library to achieve automatic retry to enhance stability.

In Python, variables defined inside a function are local variables and are only valid within the function; externally defined are global variables that can be read anywhere. 1. Local variables are destroyed as the function is executed; 2. The function can access global variables but cannot be modified directly, so the global keyword is required; 3. If you want to modify outer function variables in nested functions, you need to use the nonlocal keyword; 4. Variables with the same name do not affect each other in different scopes; 5. Global must be declared when modifying global variables, otherwise UnboundLocalError error will be raised. Understanding these rules helps avoid bugs and write more reliable functions.

Yes, you can parse HTML tables using Python and Pandas. First, use the pandas.read_html() function to extract the table, which can parse HTML elements in a web page or string into a DataFrame list; then, if the table has no clear column title, it can be fixed by specifying the header parameters or manually setting the .columns attribute; for complex pages, you can combine the requests library to obtain HTML content or use BeautifulSoup to locate specific tables; pay attention to common pitfalls such as JavaScript rendering, encoding problems, and multi-table recognition.

The way to access nested JSON objects in Python is to first clarify the structure and then index layer by layer. First, confirm the hierarchical relationship of JSON, such as a dictionary nested dictionary or list; then use dictionary keys and list index to access layer by layer, such as data "details"["zip"] to obtain zip encoding, data "details"[0] to obtain the first hobby; to avoid KeyError and IndexError, the default value can be set by the .get() method, or the encapsulation function safe_get can be used to achieve secure access; for complex structures, recursively search or use third-party libraries such as jmespath to handle.
