Lazy evaluation
When Python is working its way through the following script, which line will it get to when the 'Converting to percentage'
message is printed?
from dask import delayed
def fraction_to_percent(x):
percentage = x * 100
print('Converting to percentage')
return x
frac = 0.3
percentage = delayed(fraction_to_percent)(frac)
computed_percentage = percentage.compute()
print(percentage)
print(computed_percentage)
You can use the console to help you figure out the answer. The fraction_to_percent()
function is already available in the session.
