pip install python-dotenv

EnvServ - Model view for easy Python development

Example №1:

# file: .env
FirstVar = Hello, world!
SecondVar = 42
ThirdVar = 23

from envserv import EnvBase

class MyEnv(EnvBase):
    __envfile__ = '.env'

    FirstVar:str
    SecondVar:int
    ThirdVar:float

env = MyEnv()

print(env) # EnvServ(FirstVar:<class 'str'> = Hello, world!, SecondVar:<class 'int'> = 42, ThirdVar:<class 'float'> = 23.0)
print(env.FirstVar, env.SecondVar,env.ThirdVar) # Hello, world! 42 23.0
print(type(env.FirstVar), type(env.SecondVar), type(env.ThirdVar)) # <class 'str'> <class 'int'> <class 'float'>

Example №2:

from envserv import EnvBase

class MyEnv(EnvBase):
    __envfile__ = '.env'

    FirstVar:str

env = MyEnv()

env.FirstVar = "New variable value" # Also changes a variable in the .env file

print(env) # EnvServ(FirstVar:<class 'str'> = New variable value)
print(env.FirstVar) # New variable value
print(type(env.FirstVar)) # <class 'str'>

Example №3:

# file: .env
pass = 100

from envserv import EnvBase, variable

class MyEnv(EnvBase):
    __envfile__ = '.env'
    
    pass_:int = variable(alias='pass',overwrite=False)

env = MyEnv()

print(env) # EnvServ(pass_:<class 'int'> = 100)
print(env.pass_) # 100
print(type(env.pass_)) # <class 'int'>

env.pass_ = 1 # envserv.errors.EnvVariableError: Error overwriting variable pass_: It cannot be overwritten

Example №4:

# file: .env
A = Text
ERR = this is error
C = [1, 2, 3, 4, 5]
D = {1: 2, 3: 4}
E = null
F = {1,2,3,4,5}

from envserv import EnvBase, Variable

class MyEnv(EnvBase):
    __envfile__ = '.env'
    
    A:str
    B:int = Variable(alias="ERR", error=False)
    C:list
    D:dict
    E:None
    F:set
    not_in:str = "test"


env = MyEnv()
print(env.all())
print(env.all(toString=True))

# Вывод:
# {'A': 'Text', 'B': 'this is error', 'C': [1, 2, 3, 4, 5], 'D': {1: 2, 3: 4}, 'E': None, 'F': {1, 2, 3, 4, 5}, 'not_in': 'test'}
# {'A': 'Text', 'B': 'this is error', 'C': [1, 2, 3, 4, 5], 'D': {1: 2, 3: 4}, 'E': None, 'F': [1, 2, 3, 4, 5], 'not_in': 'test'}
