lstrip() print(left_trimmed_text) # Output: "I love learning Python! " Powered By .lstrip() is useful when you need to clean up strings that start with unwanted spaces or characters, such as in lists of names or categorical data. 3. Removing trailing whitespace from strings in Python ...
We frequently call these 0/1 variables “dummy” variables, but they are also sometimes called indicator variables. In machine learning, this is also sometimes referred to as “one-hot” encoding of categorical data. Pandas Get Dummies Creates Dummy Variables from Categorical Data Now that you un...
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 ...
Ways to encode categorical variables Categorical variables are generally addressed as ‘strings’ or ‘categories’ and are finite in number. Here are a few examples: The city where a person lives: San Francisco, Chicago, Las Vegas, Seattle, etc. ...
In any case: we usually want to exclude outliers from data analysis. So how to do so in SPSS? We'll walk you through 3 methods, using life-choices.sav, partly shown below.In this tutorial, we'll find outliers for these reaction time variables....

Select whether you want your cross tab in the existing worksheet or a new one, and click OK. As shown in the figure, we are selecting a new worksheet for the table. Go to the PivotTable Fields section on the right side of the spreadsheet. You will find the two selected variables- Tea...
Let’s say you want to find the average marks in each Major. What would you do? Choose Marks column Apply mean function Apply round function to round off marks to two decimal places (optional) groups['Marks'].mean().round(2) Major ...
Here, we’ve faceted on two categorical variables,cutandcolor. To do this, we usedbothfaceting parameters:facet_colandfacet_row. Specifically, we setfacet_col = 'cut'andfacet_row = 'color'. As you can see in the output plot, this has faceted the original histogram into multiple panels, ...
This can happen, for example, when the dataset contains a large number of categorical variables. Why are categorical variables a problem? Let’s find out Categorical variables Most algorithms can’t deal with categorical variables directly. So, we are using a process called dummification to turn...
