7 Code style

To make your programs easier to read and understand, both for yourself (especially when revisiting your code later) and for others, follow these guidelines:

Organize your code into reusable blocks, such as functions.
Use short but descriptive names for functions, parameters, and variables, following the snake_case style.
```
# Bad
N, temp, currentScore

# Good
student_count, temperature, current_score
```

Separate functions with two empty lines.

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


def multiply(a, b):
    return a * b

Optionally, use a single empty line to separate larger parts of the code.

Document your code using comments (#) and docstrings:

def calculate_area(radius):
    """
    Calculate the area of a circle given its radius.

    Parameters:
        radius (float): The radius of the circle.

    Returns:
        float: The area of the circle.
    """
    return np.pi * radius**2

Always use 4 spaces per indentation level.

# Bad indentation
for i in range(10):
 print(i)
 if i % 2 == 0:
       print("Even number")

# Good indentation
for i in range(10):
    print(i)
    if i % 2 == 0:
        print("Even number")

Tip: In Jupyter notebooks (and many other Python editors), pressing Tab inserts 4 spaces automatically.

Avoid overly long lines. Python’s style guide (PEP 8) suggests a maximum of 79 characters per line.

Follow the Whitespace in Expressions and Statements section of PEP 8. A few examples:

# Bad
result=3+4*5

# Good
result = 3 + 4 * 5

# Bad: no spaces after commas
numbers = [1,2,3,4,5]
names = ["Alice","Bob","Charlie"]

# Good: spaces after commas improve readability
numbers = [1, 2, 3, 4, 5]
names = ["Alice", "Bob", "Charlie"]

# Bad: cramped keywords
if(a>0 and a<10):
    print("It is between 1 and 9")
while(i<5):
    print(i)

# Good: spaces improve readability
if a > 0 and a < 10:
    print("It is between 1 and 9")
while i < 5:
    print(i)

# Bad: no spaces after commas, a space after the function name
def greet(name,age):
    print (f"Hello {name}, you are {age} years old")

# Good: space after commas, no space after the function name
def greet(name, age):
    print(f"Hello {name}, you are {age} years old")

Use tools such as Pylint and Black to check or fix code that violates PEP 8.
