The main issue at hand is determining the significance of the intermediate values. When working with a series of function calls like f(g(h(x)), should h(x) or g(...) be considered as standalone entities that warrant their own names?
If they do hold value independently, it might be beneficial to break down the calls into separate variable assignments:
response = fetch(url)
process(response)
return result(response)
However, if these intermediate values are not crucial, it's best to maintain them within the same line:
y = triple(cube(sum(numbers))
PEP20 states:
It is recommended to favor flat structures over nested ones.
Sparse code is preferable to dense code.
Prioritize readability.
To adhere to these principles, we can extract function calls like this:
parentheses_result = parenthesis()
nested_result = nested(parentheses_result)
using_result = using(nested_result)
function(using_result)
However, it's important to note that there are exceptions. Sometimes, as @uʍop ǝpısdn pointed out, nesting function calls may be acceptable. The decision should be based on the clarity and comprehension of the code, whether storing intermediate results in variables enhances or hinders understanding.
