Documentation

pyis has lots of functions that we will name them and say an aexample for each of them.

First import it.

from pyis import *

• version for check version

print(version)

• is_set() is a function that check variable is set or not.

i = "Hello"
ii = None

is_set(i)  # Returns True
is_set(ii)  # Returns False

• is_empty() is a function that check variable is empty or not.

e = "Hey"
ee = None

is_empty(e)  # Returns False
is_empty(ee)  # Returns True

• is_number() is a function that check variable is int or not.

v1 = 18
v2 = "string"

is_number(v1)  # Returns True
is_number(v2)  # Returns False

• is_string() is a function that check variable is str or not.

v1 = "Annahita"
v2 = 3.14

is_string(v1)  # Returns True
is_string(v2)  # Returns False

• is_float() is a function that check variable is float or not.

v1 = 3.14
v2 = ['hi', 'hey', 'hello']

is_float(v1)  # Returns True
is_float(v2)  # Returns False

• is_list() is a function that check variable is list or not.

v1 = ['github', 'gitlab']
v2 = 2021

is_list(v1)  # Returns True
is_list(v2)  # Returns False

• is_bool() is a function that check variable is bool or not.

v1 = True
v2 = "false"

is_bool(v1)  # Returns True
is_bool(v2)  # Returns False

• is_positive() is a function that check variable is positive or not.

v1 = 20
v2 = 5 - 7

is_positive(v1)  # Returns True
is_positive(v2)  # Returns False

• is_negative() is a function that check variable is negative or not.

v1 = 10 - 30
v2 = 1

is_negative(v1)  # Returns True
is_negative(v2)  # Returns False

• is_zero() is a function that check variable is zero or not.

v1 = 0
v2 = 1

is_zero(v1)  # Returns True
is_zero(v2)  # Returns False

• is_function() is a function that check variable is function or not.

def hello(name):
    print(f"Hello {name}")


is_function(hello)  # Returns True

Examples

Here are some examples that you can get the point better.

Numbers, check number is float or int. Then check is positive or negative or zero

Here we use is_number to check if input is int and is_float to see input is float.

then we use functions for check value. As you know, we have:

• is_positive for check if number is more than 0.
• is_negative for check if number is less than 0.
• is_zero for check if number is exactly 0.

number = input("Give me number")

# Check number is int or not
if is_number(number):
    # Number is more than 0 function
    if is_positive(number):
        print("Number is positive")
    # Number is less than 0 function
    elif is_negative(number):
        print("Number is negative")
    # Number is equal to 0 function
    elif is_zero(number):
        print("Number is zero")
# Check number is float or not
elif is_float(number):
    # Number is more than 0 function
    if is_positive(number):
        print("Number is positive")
    # Number is less than 0 function
    elif is_negative(number):
        print("Number is negative")
    # Number is equal to 0 function
    elif is_zero(number):
        print("Number is zero")

Set or empty and talking about tuple, list and dictionary

Think there is a list or dictionary that you want to check values.

For check if var is:

• list we use is_list.
• tuple we use is_tuple.
• dict we use is_dict.

So we use is_set to check if var is set or not. For check is var is empty we use is_empty.

tpl = (1, 2, 5)
l = ['Hi', 10]
dct = {'name': None}

# Function returns ( True ). Parm is dictionary
if is_dict(dct):
    # Here is a tuple.
    if is_tuple(tpl):
        print("This is a tuple")
    # Lets check list
    if is_list(l):
        # See is it set or not. Returns ( True )
        if is_set(l[1]):
            print("This item is set")
    # Here we get ( True ). Parm is not set. It is empty
    if is_empty(dct['name']):
        print("This var is empty")

Strings and Booleans

Time of say some examples for strings and booleans.

When there is something and you want to check is it string you can use is_string. We do same for bool, is_bool for see var is boolean or not.

So we know this two functions now:

• is_string for check strings.
• is_bool to see var is boolean

lst = ['False', 'amir', True]

# Here it will returns ( True ). Why? Item is string
if is_string(lst[0]):
    print("Item 1 is string")

# Now we get ( False ). As you can see, item is string
if is_bool(lst[1]):
    print("This item is boolean")

# Nice ( True ). Item is boolean
if is_bool(lst[2]):
    print("I can see a boolean")

Functions checking

See, think there is callable var. How do you check? You can use is_function to check it.

So, how user can check functions?

• is_function for check function

def you(name, friend):
    print(f"Hello {name} and {friend}!")


# Get True or False. You is a function, so it returns ( True )
if is_function(you):
    print("Look, a function!")
