# Basics

`print("Hello world ")`

## variables

### Strings
`name = "poli"` this is a string
`print(name[0])`
`print(name[0:2])`

### numbers
`age = 22` this is an integer
`price = 0.99` this is a float
`age += 1` this is the same as `age = age +1`

### list
`bands = ["rammstein", "sabaton", "amaranthe"]` this is a list
`bands.append("nightwish")`

## conditions:

band = "rammstein"

if band in bands:
    print("Have it already")
else: 
    print("new band")
    bands.append(band)

meal = 'pizza'
type = 'salami'

if meal == 'pizza' and type == 'salami': 
    print("eat")
elif meal == 'foul':
    print("eat more")
else: 
    print("call ayham")

## Loops:

### for Loop

bands = ["rammstein", "sabaton", "amaranthe"]

for band in bands:
    print(band)

### while loop

number = 0 
while number <= 10:
    print(number)
    number += 1

## prime number example

def IsPrime(target):
  listNumbers = range(2, target)

  for number in listNumbers:
    if (target%number) == 0:
      print(str(target) + " is not a prime number")
      return

  print(str(target) + " is a prime number")

def AllPrimes(limit):
  listNumbers = range(2, limit+1)
  for number in listNumbers:
    print(number)
    IsPrime(number)

AllPrimes(10)
