In Python, parentheses are used to enclose function arguments, and square brackets are used to access elements of a list or dictionary. Curly brackets are not used in Python. What is the difference between square brackets and curly brackets?
While Python provides a C API for thread-local storage support; the existing Thread Local Storage (TLS) API has used int to represent TLS keys across all platforms. This has not generally been a problem for officially-support platforms, but that is neither POSIX-compliant, nor portable in any...
In Python, declarations are not explicitly required for variables. Variables are dynamically typed and are created automatically when a value is assigned to them. Can I declare a constant array in Java? Yes, in Java, you can declare an array as final to create a constant array. This ensures...

fp- Use Frame Pointers for the call graph.This is the default. dwarf- Use DWARF for the call graph (adds the--call-graph dwarfargument to theperfcommand) smart- Run bothfpanddwarf, then choose the result with the highest average of stack frames count, per process. ...
False Positive (FP) False Negative (FN) Create a matrix Once the outcomes have been classified, the next step is to present them in a matrix table, to be further analyzed using a variety of metrics. Confusion matrix practical example Let’s go through a practical example to demonstrate this...

Absolutely. REPL is a fantastic tool for data analysis and exploration, especially in languages like Python with libraries like NumPy and Pandas. You can load datasets, manipulate data, and visualize results interactively. This makes it easier to understand the data, test hypotheses, and refine ana...
4. Use gen = rdkit.Chem.rdFingerprintGenerator.GetMorganGenerator(radius, fpSize) to create a Morgan generator object of a given radius and size fpSize. Then call gen.GetFingerprint(mol), gen.GetCountFingerprint(mol), gen.GetSparseFingerprint(mol), or gen.GetSparseCountFingerprint(mol) to ...
