This makes it ideal for scenarios where you need to handle different data types within a single function while maintaining a clean control flow.
from ovld import ovld
@ovld
def process(x: int):
return x * 2
@ovld
def process(x: str):
return x.upper()
print(process(5)) # 10
print(process("auto")) # AUTOUsing Ovld for Python function overloading in automation ensures your code remains maintainable as your workflows scale. For more details, check out the Ovld documentation.
