Python Valideer class library document download
Python Valideer is a Python class library for data verification.It can help developers easily verify the input data in the application, thereby improving the accuracy and reliability of the data.Python Valideer provides a set of powerful verifications, including type verifications, range verifications, and custom verifications to meet various verification needs.
The main functions of this type of library include:
1. Type verification: The type of data can be verified, such as string, integer, floating point number, etc.
2. Scope verification: It can verify whether the data is within the specified range, such as whether the number is within the specified interval.
3. Must -fill item verification: It can verify whether the data exists to ensure that the required items are not empty.
4. Custom verification: You can define customized verification rules according to actual needs.
The following is a simple example code that demonstrates how to use Python Valideer for data verification:
python
import valideer
# Definition verification rules
schema = {
"name": {
"type": str,
"required": True
},
"age": {
"type": int,
"min": 0,
"max": 120
}
}
# To verify data
data = {
"name": "Alice",
"age": 25
}
# Data verification
try:
valideer.validate(data, schema)
Print ("Data Verification Pass!")
except valideer.ValidationError as e:
Print ("Data verification failed:", e)
In the above example, we first define a verification rule SCHEMA, including verification rules for Name and Age.Then define the data data to be verified, and call the valueer.Validate method for data verification.If the data verification is passed, print the "data verification pass!", Otherwise print the relevant information about the failure of the verification.
In addition to the above basic verification functions, Python Valideer also provides rich verifications and highly flexible configuration options, which can meet various complex verification needs.You can learn more about Python Valideer through reading detailed documents.
