Conditions

In the previous parts, you learned about if and program control flow methods.

All of them are using Conditions. Conditions help you to handle program flow.

for example:

if <this is condition>
    # ...
endif

Here, you can learn all of condition features.

Operators

<: less than operator

This operator checks Is a value less than other value.

for example:

if 10 < 100
endif

if 900 < 5
endif

$age = 40
if $age < 70
endif

>: grater than operator

This operator checks Is a value grater than other value.

for example:

if 40 > 30
endif

if 7 > 50
endif

$age = 90
if $age > 18
endif

<= less or equals operator, >= grater or equals operator

this operator checks is a value less/grater or equals another value.

for example:

if 100 <= 100
endif

# ...

println(100 <= 100) # True
println(100 >= 200) # False
$age = 18
println($age <= 18) # True
println($age >= 18) # True
println($age >= 100) # False
# ...

== equals operator, != not equals operator

This operator checks that Is a value equals/not equals another value.

for example:

$age = 39

if $age == 39
endif

if $age != 100
endif

and & or

This is a very important and useful logic. this helps you to combination conditions.

for example:

$age = 18
$country = 'somecountry'
if $age >= 18 and $country == 'somecountry'
endif

in the above example, both of condtions should be True to result of all of condition return True. if one or both of them are false, result is false.

$age = 18
$country = 'somecountry'
if $age >= 18 or $country == 'somecountry'
endif

In the above example, if ONE OR BOTH of the conditions seprated with or are True, result is True.

Also you can use both of and and or:

if $age > 18 and $age < 50 or $name == 'manager'
endif

not keyword

The not keyword in the first of condition, reverses that.

for example:

if not $age > 18
endif

Condition order

To set order of conditions(Like math operators), you should use ().

for example:

if $x and ($y or $x)
endif

The Pashmak condition system is handled by python. You can read more about conditions here.
