Python List Methods

1. sort()
2. Math Modules
3. Random Modules
4. Datetime

 sort()

Math Module

• Remainder() or %

import math
print (26%5)

• sqrt()

import math
numbers = 144
print (math.sqrt(numbers))

Random Module

• random()

import random
print (random.randint(0, 9))

 

Python Operators

First_name = 'Reemaz'
second_name = 'alaa'
print (First_name*3)

First_name = 'Reemaz'
second_name = 'alaa'
print (First_name + second_name)

Note: To add a space between them, add a " "

First_name = 'Reemaz'
second_name = 'alaa'
print (First_name + ' ' + second_name)

For Example

import datetime
date = datetime.date(2020, 2, 13)
