Basically this module is for saving data specially variables including other data like images or text files outside your code so that you never ever lose them.
Let's say you've created a game with pygame. There is a high score system and you want to save the highest score in an online database so that users all over the world can see the highest score. Here comes the usage of PyDataman. Yes you can also do it without PyDataman, but you've to write more to do so.
Again, let's say you don't want a variable to be reset everytime you run your code, here you must use PyVariable. Using PyDataman, you can save a variable in your drive (offline) or in an online database. It's really simple enough.

One more feature, you can save any of your files in an online databse and download from any device whenever and wherever you need them.

Installing the module is quite easy ;)
Simple open your terminal and enter pip install pydataman.

Note: If you are having any problem with the installation, feel free to contact me in Gmail and in facebook

Save your variables outside your code so that whenever you restart your code, you won't lose them. Here's how to do it -

Simply import the module. Call the save(var_name, value) method with the name and the value of a variable as argument to store your data locally and call read(var_name) to read the value. The value will already be in your desired data type, no need to covert again.

Also, call exists() method with name of a variable as argument to check if the variable exists.
Note: It will return True or False.

Here is a sample code -

import pydataman

pydataman.save("Name", "John")  # This will store the variable Name with the value John
LocalName = pydataman.read("Name")  # This will read the value of Name from files and store in LocalName
print(LocalName)  # This will print John

Another example of checking if a variable exists -

import pydataman

if pydataman.exists("X"):  # The method returns true if the variable exists in your folder
      print("The variable X exists")
else:
      print("The variable X doesn't exist")

Store your variables online so that everytime you restart your code, you don't lose the values. Even you can create a variable from a device and access it's value from another. Here's how to do these -

{
  "rules": {
    ".read": "true",
    ".write": "true",
  }
}

Everything is now ready. Simply call the save() method with the name and the value of a variable as argument to store your data online and call the read() method with the name of your variable as argument to read the value of it.
Note: The returned value will automatically be in your desired data type.
Also, call exists() method with name of a variable as argument to check if the variable exists.It will return True or False.

Here is a sample code -

import pydataman

data = pydataman.CloudVariable(The_Url_You_Copied)

data.save("Name", "John")  # This will store the variable Name with the value John
LocalName = data.read("Name")  # This will read the value of Name from your database and store in LocalName
print(LocalName)  # This will print John

Another example of checking if a variable exists -

import pydataman

data = pydataman.CloudVariable(The_Url_You_Copied)

if data.exists("X"):  # The method returns true if the variable exists in your database
      print("The variable X exists")
else:
      print("The variable X doesn't exist")

Store your files online like variables, and here is how to do it -

• The dictionary you recently copied.
• The directory of you private key file

Everything is now ready. Create an object of the class NewFile() with the directory of your file (in your local device) as argument. To upload your file, call the upload method of NewFile() instance, and call the download() method to download the file.
