Extracting the correct data from a CSV file

[snippsat]

or "Print the moons in alphabetic order"

Just to give help with this task,it's the same start for the other task as you use DataFrame sat_df.
It's a typically dataset to be used with Pandas,you should mention what to use.
As regulars Python and Pandas are quite different.

import pandas as pd

file = 'satellites.csv'
sat_df = pd.read_csv(file)
# Sort the moons alphabetically
moons_sorted = sat_df.sort_values(by='name')
print(moons_sorted[['planet', 'name']])

Output:
      planet      name
17   Jupiter  Adrastea
93    Saturn   Aegaeon
107   Saturn     Aegir
33   Jupiter     Aitne
101   Saturn  Albiorix
..       ...       ...
133   Uranus   Titania
151   Uranus  Trinculo
158  Neptune    Triton
132   Uranus   Umbriel
94    Saturn      Ymir
