I am using python to interact with a kubernetes cluster. I am trying to retrieve the number of releases by using the following code:

number_of_releases = subprocess.getoutput(f"helm history myRelease --namespace myNamespace -o json | jq length")

When I run print(number_of_releases) I get 2 (which is my expected result from using normal kubectl) and running print(type(number_of_releases)) shows that this is a string. However, when I try to use int(number_of_releases) I get an error saying invalid literal for int() with base 10.

I have tried no_whitespace_variable = number_of_releases.strip() but curiously the length of the variable no_whitespace_variable turns out to be 205. Does anyone know what might be happening, or have any further suggestions for troubleshooting?
