In the special case that all variables are of the same type, much of this information is redundant: it can be much more efficient to store data in a fixed-type array. This imports just the package numpy, and renames it to np so that you can dereference it by using the dot operator on np. simply change int64 to "int64" inside your dtype dictionary. This means that every Python object is simply a cleverly-disguised C structure, which contains not only its value, but other information as well. But what this type-flexibility also points to is the fact that Python variables are more than just their value; they also contain extra information about the type of the value. 587), The Overflow #185: The hardest part of software is requirements, Starting the Prompt Design Site: A New Home in our Stack Exchange Neighborhood, Temporary policy: Generative AI (e.g., ChatGPT) is banned, Testing native, sponsored banner ads on Stack Overflow (starting July 6).
