Structuring Python Programs
In this tutorial, we are going to see some best practices for structuring the Python programs. Let's see one by one
Use a tab for indentation
Using a tab for indentation in the code make code more readable instead of using random spaces for multiple functions and methods. You can set the number of spaces for a tab in any code editors' settings.
Example
# example def sample(random): # statement 1 # statement 2 # ... return random
Don't write more than 79 characters in a line
Writing more than 79 characters in a line is not recommended Python. Avoid this by breaking line into multiple lines using the escape character (). See the example below.
Example
# example def evaluate(a, b, c, d): return (2 ** (a + b) / (c // d) ** d + a - d * b) \ - (3 ** (a + b) / (c // d) ** d + a - d * b)
If you have to check multiple conditions in if statement, then it will be more than 79 characters. Use any one of the following methods.
Example
if (
a + b > c + d and
c + d > e + f and
f + g > a + b
):
print('Hello')
if a + b > c + d and \
c + d > e + f and \
f + g > a + b:
print('Hello')Using docstrings
Use docstring in the functions and classes. We can use the triple quotes for the docstrings. some examples below.
Example
def sample(): """This is a function""" """ This is a function """ class Smaple: """This is a class""" """ This is a class """
