python code optimization
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)

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)]

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
