Write your own generator expressions
You are familiar with what generators and generator expressions are, as well as its difference from list comprehensions. In this exercise, you will practice building generator expressions on your own.
Recall that generator expressions basically have the same syntax as list comprehensions, except that it uses parentheses ()
instead of brackets []
; this should make things feel familiar! Furthermore, if you have ever iterated over a dictionary with .items()
, or used the range()
function, for example, you have already encountered and used generators before, without knowing it! When you use these functions, Python creates generators for you behind the scenes.
Now, you will start simple by creating a generator object that produces numeric values.
This exercise is part of the course
Python Toolbox
Exercise instructions
- Create a generator object that will produce values from
0
to30
. Assign the result toresult
and usenum
as the iterator variable in the generator expression. - Print the first
5
values by usingnext()
appropriately inprint()
. - Print the rest of the values by using a
for
loop to iterate over the generator object.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Create generator object: result
result = ____
# Print the first 5 values
print(____)
print(____)
print(____)
print(____)
print(____)
# Print the rest of the values
for value in ____:
print(value)
