with open("FileData.txt",'r') as csvfile: reader = csv.reader(csvfile) for row in reader: print(row) (You don’t have to use the with statement here. You can open the file just as you would duringregular file handling) ['Name', 'Age', 'Gender '] ...
A full-featured operator in just 2 files: aDockerfile+ a Python file (*). Handling functions registered via decorators with a declarative approach. No infrastructure boilerplate code with K8s API communication. Both sync and async handlers, with sync ones being threaded under the hood. ...
