Errors in Chapter 1:

Section: Overview of Jupyter Notebook

programming instead programing:

Jupyter Notebook is becoming increasingly popular as a successful User Interface (UI) for Python programing.

---

Text below figure 1.5

Wrong library name: np.arange() instead of np.arramge():

Next we will learn four NumPy functions: np.arramge(), np.zeros(), np.ones(), and np.linspace().

---

Section: The np.linspace() function

Incorrect representation under the first mathematical statement:
Text Formula_B17397_01_001 is useless at this point

---

Section: Pandas functions for exploring a DataFrame
Subsection: The .info() function

function info() must be lowercase:

If you run adult_df.Info(), ...

---

Section: Pandas functions for exploring a DataFrame
Subsection: Histograms and boxplots to visualize numerical columns

Wrong function adult_df.age.box() instead of adult_df.age.plot.box():

To create the boxplot for the age column, all you need to change is the last part of the code: adult_df.age.box(). Give it a try.

---

Text below figure 1.34

Function parameter "Normalize" must be lowercase:

To get the relative frequency table, all you need to do is to specify that you want the table to be normalized: .value_counts(Normalize = True). Give it a try!

---

Text above figure 1.37

Variable CapitalNet must be begin with lowercase:

As we are only interested in the correlations between education_num, lifeNoEd, and CapitalNet, the last line of the code has removed other columns before running the .corr() function.

---

some lines later: Text below figure 1.37

Variable CapitalNet must be again begin with lowercase:

... the correlation between education_num and CapitalNet is higher, at 0.117891.

---

inside figure 1.38:

functions .var() and .describe() must be lowercase

---

Subsection under figure 1.44 Multi-level access

spelling error "sizable" instead "sizeable":

In this subchapter, we gathered sizable exposure to multi-level indexing and columns.

Thank you very much for this valuable feedback. We are finalizing the book and all of these will be fixed in that version.
