return jsonify({"message": "Hello, World!"})
if __name__ == '__main__':
app.run(debug=True)
Version Control Systems: Understanding and working with version control systems (primarily Git) is often necessary. This makes collaboration easier and keeps track of changes in the codebase.
Example Git Commands:
git init # Initialize a new git repository
git clone <repo_url> # Clone an existing repository
git add . # Stage all changes
git commit -m "message" # Commit staged changes with a message
git push # Push local changes to the remote repository
Basic Knowledge of Databases: Familiarity with SQL and basic database management (PostgreSQL, MySQL, SQLite) is often required, as many applications depend on database interactions.
Python with SQLite Example:
import sqlite3
# Connecting to SQLite database
connection = sqlite3.connect('example.db')
# Creating a cursor object
cursor = connection.cursor()
# Executing a simple query
cursor.execute('''CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, age INTEGER)''')
connection.commit()
# Closing the connection
connection.close()
Understanding of Testing: Junior developers are often responsible for writing tests to ensure code reliability. Learning to use testing frameworks like unittest or pytest is essential.
Example with unittest:
import unittest
# Simple function to convert temperature
def fahrenheit_to_celsius(fahrenheit):

Start by mastering the fundamentals of Python. Make sure you understand:
for, while) and conditionals (if, elif, else).Here’s a quick example of a Python function utilizing control flow:
def custom_greeting(time_of_day, name):
if time_of_day == 'morning':
return f"Good morning, {name}!"
elif time_of_day == 'afternoon':
return f"Good afternoon, {name}!"
else:
return f"Good evening, {name}!"
print(custom_greeting('morning', 'Alice'))
Understanding OOP principles is crucial. Learn about:
Example of a simple class:
class Dog:
def __init__(self, name, age):
self.name = name
self.age = age
def bark(self):
return f"{self.name} says woof!"
my_dog = Dog(name="Buddy", age=3)
print(my_dog.bark())
Begin by focusing on popular libraries and frameworks that are often used in entry-level positions:
Example of using the Pandas library:
import pandas as pd
data = {
'name': ['Alice', 'Bob', 'Charlie'],
'age': [25, 30, 35]
}
df = pd.DataFrame(data)
print(df)
Follow best practices to write clean, efficient, and manageable code:
unittest or pytest.Example of a simple unit test with the unittest framework:
import unittest
def add(a, b):
return a + b
class TestMathFunctions(unittest.TestCase):
def test_add(self):
self.assertEqual(add(10, 5), 15)
self.assertEqual(add(-1, 1), 0)
self.assertEqual(add(-1, -1), -2)
if __name__ == '__main__':
unittest.main()
