Number of decimal digits in f-strings

If we want to return a specific number of decimal digits in f-strings we can use the f'{v:.2f}' where v is our variable. For example:

import numpy as np
my_random = np.random.rand(10)

for i, n in enumerate(my_random):
    print(f'The {i} number is {n}') 

Now, if we pass the :.2f we will get 2 decimal places. For example:

for i, n in enumerate(my_random):
    print(f'The {i} number is {n:.2f}')
