We will do several examples of the groupby function. Let’s start with a simple one. The code below will group the rows based on the geography-gender combinations and then give us the average churn rate for each group.

The method parameter of the fillna function can be used to fill missing values based on the previous or next value in a column (e.g. method=’ffill’). It can be pretty useful for sequential data (e.g. time series).

“Long-term activation of your body’s stress response system, along with prolonged exposure to cortisol and other stress hormones, may put you at risk for health troubles like digestive problems, anxiety, headaches, depression, sleep problems, weight gain, memory and concentration issues, high blood pressure, [and] heart disease and stroke.”

Edit: Thanks Ron for the heads-up in the comment section. If we set the as_index parameter of the groupby function as False, the group names will not be used as the index.

we have to refer to some other pain — one that is easy to picture and usually involves a tool or weapon, like a knife, axe, or hammer. To talk about pain, we have to distance ourselves from it, separate via violence. Pain is happening to us rather than something our bodies are doing.

The fillna function is used to fill the missing values. It provides many options. We can use a specific value, an aggregate function (e.g. mean), or the previous or next value.

Pandas Groupby function is a versatile and easy-to-use function that helps to get an overview of the data. It makes it easier to explore the dataset and unveil the underlying relationships among variables.

Another way to handle missing values is to drop them. There are still missing values in the “Exited” column. The following code will drop rows that have any missing value.

After an instance of gnmi-gateway acquires a lock for a target and forms a connection, it begins to forward data into the local in-memory cache. To allow any instance of gnmi-gateway in the cluster to serve a subscription for any target in the cluster, gNMI messages are replicated from the instance with the lock to other instances in the cluster. This replication allows any clustered instance of gnmi-gateway to accept client requests for any known target.

With every instance in the cluster able to serve streams for each target, we’re able to load balance incoming clients connections among all of the cluster instances. The underlying transport for gNMI is, like most gRPC connections, HTTP/2 over TLS — so this allows us to use a simple Layer 4 load balancer between gnmi-gateway and our gNMI clients. Although we’ve chosen to use a Layer 4 load balancer, this could be substituted for a Layer 7 load balancer or an alternative load balancing solution, such as DNS load balancing.

In some cases, we need to reset the index and get rid of the original index at the same time. Consider a case where draw a sample from a dataframe. The sample will keep the index of the original dataframe so we want to reset it.

By default, categorical data is stored with the object data type. However, it may cause unnecessary memory usage especially when the categorical variable has low cardinality.

I’ll admit that there have been many times where I let my engineering work send my stress levels through the roof. Whenever this happened, I could feel the negative impacts on my sleep schedule, how I felt when I exercised, and even the food I chose to put in my body.

The axis=1 is used to drop columns with missing values. We can also set a threshold value for the number of non-missing values required for a column or row to have. For instance, thresh=5 means that a row must have at least 5 non-missing values not to be dropped. The rows that have 4 or fewer missing values will be dropped.

This means that we don’t have to troll through logcat to get this information. Instead, we can get it directly from the console where we run the launch command. Better yet, we can strip the extraneous text and leave just the launch result, making it easier to extract this data for use elsewhere.
