# Basics :
# Print
print("Hello, world!")  # it prints the text then puts a back line
import hello  # this lib just prints "Hello, world!"
print()  # this prints a blank line with a back line at the end

# Mathematical operators
print(1+1)
print(3-4)
print(2*3)
print(6/2)
print(3^2)  # this is the power
print(math.abs(-5))  # the absolute value
print(1e10)  # 1*10^10
print()

# Variables
var some_text = "Hello, world!"  # no need to put the variable type
var a = var b = 3  # you can use variable definitions in other expressions

print(some_text); print(a * b)  # the ';' is like a back line

var a ++
var b --
print(str(a)+str(b))  # 42
print(reverse(str(a)+str(b)))  # 24

# the following two lines are an example in the doc (Built-in variables)

print("You use " + __os_name__ + " " + __os_release__ + " " + __os_version__)

print(None)  # like Python's 'None'

print(var b === 3)  # like `var b = (b==3)`
print(var b <== 3)  # like `var b = (b<=3)`
print(var b <<= 3)  # like `var b = (b<3)`
print(var b >== 3)  # like `var b = (b>=3)`
print(var b >>= 3)  # like `var b = (b>3)`

# Strings
# examples of using the backslash
