Preliminaries



In [1]:

    
# import pandas as pd
import pandas as pd

Create a simulated dataset



In [2]:

    
# Create an example dataframe
data = {'score': [1,2,3,4,5]}
df = pd.DataFrame(data)
df

Does any cell equal 3?



In [3]:

    
# If any element in df.score equals three,
if (df.score == 3).any():
    # Print this
    print('Does any cells equal 3? Yes!')
# Otherwise,
else:
    # Print this
    print('Does any cells equal 3? No!')









    



Does any cells equal 3? Yes!

Do all cells equal 3?



In [4]:

    
# If all elements in df.score equal three,
if (df.score == 3).all():
    # Print this
    print('Do all cells equal 3? Yes!')
# Otherwise
else:
    # Print this
    print('Do all cells equal 3? No!')









    



Do all cells equal 3? No!
