In the preceding code block, you first import theFlaskobject from theflaskpackage. You then use it to create your Flask application instance with the nameapp. You pass the special variable__name__that holds the name of the current Python module. It’s used to tell the instance where it’...
To be a valid tag library, the module must contain a module-level variable named register that is a template.Library instance, in which all the tags and filters are registered. So, near the top of your module, put the following: from django import template register = template.Library() ...
subset() on a categorical variable A better way to do this is to use the subset() function to select the rows where the name column is equal to Dan. Notice that their needs to be a double equals sign, known as a relational operator. # This works, but is not informative nor robust ...
automatically created when you first run a program, and you’ll never need to change them. This chapter primarily covers shell startup files, which are the ones you’re most likely to modify or rewrite from scratch. Let’s first look at how much care you need to take when working on ...

Again, we know from our previous post that those should be the first two 32-bit words in our binary, so we just need to dereference those addresses using the __approm_start__ variable from our memory map. /* bootloader.c */ #include <inttypes.h> #include "memory_map.h" int main(...
All of the variables are continuous and generally in the range of 0 to 1. The output variable is a string “M” for mine and “R” for rock, which will need to be converted to integers 1 and 0. By predicting the class with the most observations in the dataset (M or mines) the ...
The name arrayName is just like naming any other variable. It can be anything that abides by Python naming conversions, in this case, myarray. The first array in array.array is the module name that defines the array() class. It must be imported before used. The first line of code does...
Building a C web scraper would have us creating many components from scratch or writing long, convoluted code files to do simple functions. When choosing a language to build our web scraper, we’re looking for simplicity and scalability. There’s no point in committing to a tool that makes ...
