This now returns a clearly-labelled dataframe that looks like the below: Name Let’s re-create our dataframe and specify a column name: import pandas as pdĭf = pd.DataFrame(names, columns=) The columns= argument takes a list-like object, passing in column headers in the order in which the columns are created. Since Pandas doesn’t actually know what to call the column, we need to more explicit and use the columns= argument. We can see that Pandas has successfully created our dataframe, but that our column is unnamed. This returns a dataframe that looks like this: 0ģ Evan Specifying Column Names when Creating a Pandas Dataframe Let’s take a look at passing in a single list to create a Pandas dataframe: import pandas as pd Because the data= parameter is the first parameter, we can simply pass in a list without needing to specify the parameter. Recall, that the data= parameter is the parameter used to pass in data. Now that you have an understanding of what the pandas DataFrame class is, lets take a look at how we can create a Pandas dataframe from a single list. Because of these many options, lets see how you can create a dataframe from Pandas lists! Create a Pandas Dataframe from a Single List The data= parameter can contain an ndarray, a dictionary, a list, or a list-like object. Instead, you can use the data= parameter, which, positionally is the first argument. But in this tutorial, you won’t be creating an empty dataframe. We’ve covered creating an empty dataframe before, and how to append data to it. You can create an empty dataframe by simply writing df = pd.DataFrame(), which creates an empty dataframe object. potentially heterogeneous means that it can contain different datatypes.size-mutable means that its size can change.two-dimensional means that it contains rows and columns.The pandas Dataframe class is described as a two-dimensional, size-mutable, potentially heterogeneous tabular data.
