Activity 1.01: Implementing Pandas Functions

1. Open a new Jupyter notebook.
2. Use pandas to load the Titanic dataset:

   import pandas as pd
   df = pd.read_csv(r'../Datasets/titanic.csv')

3. Use the head function on the dataset as follows:

   # Have a look at the first 5 sample of the data
   df.head()

   The output will be as follows:

   Figure 1.26: First five rows

4. Use the describe function as follows:

   df.describe(include='all')

   The output will be as follows:

   Figure 1.27: Output of describe()

5. We do not need the Unnamed: 0 column. We can remove the column without using the del command, as follows:

   del df['Unnamed: 0']
   df = df[df.columns[1:]] # Use the columns
   df.head()

   The output will be as follows:

   Figure 1.28: First five rows after deleting the Unnamed: 0 column

6. Compute the mean, standard deviation, minimum, and maximum values for the columns of the DataFrame without using describe:

   df.mean()

   The output will be as follows:

   Figure 1.29: Output...
