I have a small question about f format notation.
This works for me:
print("Sample counts per class:\n{}".format(
{n: v for n, v in zip(cancer.target_names, np.bincount(cancer.target))}))
But this doesn’t:
print(f"Sample counts per class:\n {n: v for n, v in zip(cancer.target_names, np.bincount(cancer.target))}")
it gives me this error:
Traceback (most recent call last):
File "C:\Users\User\machinelearn\chapter2.py", line 13, in <module>
print(f"Sample counts per class:\n {n: v for n, v in zip(cancer.target_names, np.bincount(cancer.target))}")
NameError: name 'n' is not defined
Have been searching the internet for a while to find a solution, but cannot find anything that is comprehensible for me.
edit:
data = {n: v for n, v in zip(cancer.target_names, np.bincount(cancer.target))}
print(f"Sample counts per class:\n {data}")
This works, but is not optimally how I would like to write it.
