Оптимизация кода Python

Here is a good optimization trick for many:


#INSTEAD OF:
list = []
for i in range(number):
    list.append(value)
 
#USE:
list = [value for i in range(number]


#INSTEAD OF:
for i in range(len(list)):
    #Do something
   
USE:
for i, value in enumerate(list):
    #Do something
    
    
APPLYING IT:

#THIS:
matrix = [[0 for i in range(number1)] for j in range(number2)]

#IS BETTER THAN:
matrix = []
for i in range(number1):
    row = []
    for j in range(number2):
        row.append(0)
    matrix.append(row)

OPTIMIZATION FOR PYTHON: TIP 2 - 4

2 - When importing modules you can import them all in a single line:

import module_1, module_2, module_3, etc...


3 - When importing everything from a module use *:

from random import *

We imported everything from the 'random' module using *, now we dont need to use 'random.'
FUN FACT: Not using module. increases performance since module. uses the get_attr function which
decreases performance


4 - When importing only a few things from a module combine the two tips above:

from random import randint, choice

#Now we only import the things we want while also iincreasing performance and start-up time

HOW TO WRITE BETTER CODE IN PYTHON | TIP #1

1 - List comprehension
#DONT DO THIS:

list = []
for i in range(number):
    list.append(i)
    
#DO THIS:

list = [i for i in range(number)]
