my_variable = 10
In this example, my_variable
is a variable that holds the integer value 10
.
### Managing Variables
You can perform various operations on variables, such as:
- Reassigning Values:
python
my_variable = 20
- Performing Operations:
python
my_variable += 5 # Increment by 5
- Using with Other Variables:
python
another_variable = my_variable * 2
- Printing Values:
python
print(my_variable) # Outputs: 25
Variables in Python are dynamically typed, meaning you don't have to declare their type explicitly. You can also use various data types like strings, lists, dictionaries, etc., as variable values.

, set
, and unset
. These methods allow you to create, update, and delete variables programmatically.
2. Example Code:
python
from prefect import get_client
client = get_client()
# Set a variable
client.variables.set(name="my_variable", value="some_value")
# Get a variable
value = client.variables.get(name="my_variable")
print(value)
# Unset a variable
client.variables.unset(name="my_variable")
3. Variable Characteristics:
- Prefect variables are dynamically-named, mutable string values.
- They can store any JSON type and are cached for quicker retrieval.
- Variables are not encrypted, so avoid storing sensitive information in them.
4. Variable Naming Conventions:
- Names can have up to 255 characters and must be unique.
- They should only contain lowercase alphanumeric characters or underscores.
5. Additional Resources:
- For detailed information, you can refer to the Prefect Variables Documentation.
This should give you a good start on managing variables in Prefect using Python. If you have more specific needs or questions, feel free to ask!
