Using the keyword Yield in Python
Rather than computing the values at once and returning them in the form of a list, Yield is used to produce a series of values over time.
Where and when to use yield?
The yield keyword is often used as a replacement for the return statement, but nstead of returning a specific value, yield returns a sequence of values. This is particularly useful when we are looking to iterate over a sequence rather than store it in the memory, or in search tasks where the intended value must be returned as soon as it’s located.
Code
The following code uses yield to compute the cube of numbers:
# Using Returndef myReturnCubeFunction():mylist = range(10)for i in mylist:list= i*i*ireturn listcallReturn = myReturnCubeFunction()print("Using return:",callReturn)# Using Yielddef myYieldCubeFunction():mylist = range(10)for i in mylist:yield i*i*icallyield = myYieldCubeFunction()print("Using yield:")for i in callyield:print(i)
