In this way, you can use the generator without calling a function: Python csv_gen = (row for row in open(file_name)) This is a more succinct way to create the list csv_gen. You’ll learn more about the Python
A Python generator is a type of function that allows us to process large amounts of data quickly and efficiently. They are generally thought of as a complex concept in Python. That's why they are consistently seen on job interviews. Generators aren't just an arcane bit of programming used ...
The yield keyword in Python turns a regular function into a generator, which produces a sequence of values on demand instead of computing them all at once.

The last thing we want to create is the string function that will tell Python how to print this object. Again, we use themapfunction to convert each property by printing the name of the property and then its value. Notice that in the map return value, we are adding a comma and a plu...
