There are several text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Inspect the first five rows of the dataset using the head() function.”

A block of code is set as follows:

def plot_salary_distribution(df):
    plt.figure(figsize=(10, 6))
    sns.histplot(data=df, x='Average Salary', kde=True)
    plt.title('Distribution of Salaries')
    plt.xlabel('Average Salary')
    plt.ylabel('Count')
    plt.show()

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

Biotech & Pharmaceuticals                  66
IT Services                                61
Unknown Industry                           60
Computer Hardware & Software               56
Aerospace & Defense                        46
Enterprise Software & Network Solutions    43

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “ Drag the Longitude and Latitude marks into Columns and Rows, respectively.”
