Imagine we have a dataframe, df. What would be the purpose for running code like the
below? (why would we run it?) - answerto look for, retrieve a value from df

imagine we have a pandas dataframe we have named 'df'
the dataframe consists of 2 columns
"col1" is 30 values long, and is a random mix of the letters 'a', 'b', and 'c'.
"num1" is also 30 values long, and is a random set of numerical data (all integers).
Which of the following would give you the mean of the numerical (num1) column,
grouped by the values from column "col1"? - answerdr.groupby('col1').mean()

What is the shape of the following numP array?

np.random.seed(1995)
x = np.random.randn(2, 2, 2, 2)
print(x.shape)
x - answer(2, 2, 2, 2)

what is the output of the following code?

import numpy as np
list1 = [5, 5, 5]
list2 = [10, 10, 10]
np_list1 = np.array(list1)
np_list2 = np.array(list2)
np_list1/np_list2 - answerarray([0.5, 0.5, 0.5)]
