To understand what yield does, you must understand what generators are. And before you can understand generators, you must understand iterables. Iterables When you create a list, you can read its items one by one. Reading its items one by one is called iteration: mylist is an iterable. When you use a list comprehension, you create a list, and so an iterable: … Read more
4 I take an index on the barcode column as a given. You could save space if you stored the codes as numbers. Space is time as less bytes can be read faster. Also, the lookup should be faster on numbers. The leading zeros can be reconstructed when needed as UPC-A is a fixed-length code.
The json module already implements some basic pretty printing with the indent parameter that specifies how many spaces to indent by: To parse a file, use json.load():

Save them to your C:\Windows\SysWOW64 folder as well (if you have a 64-bit operating system). Now try running your code file in Python and it will load the graph in couple of seconds.
x86 is for a 32-bit OS, and x64 is for a 64-bit OS
