In order to cope with multiple dimensions we have to define nested for loops. Like other programming languages, for loops in Python are a little different in the sense that they work more like an iterator and less like a for keyword. Python range ExamplesUse range, an immutable sequence type, in for-loops and to create lists. It was not necessary to loop the range() and using list() method we could directly convert the output from range to list format.

Note that zip with different size lists will stop after the shortest list runs out of items. Option 2 – Using Iteration to Identify Unique Values. Whenever you create a list in Python, you’ll need to make a distinction between: Lists that contain strings, where each item within the list will be placed within quotes: ListName = [‘Item1’, ‘Item2’, ‘Item3’,….] In Python, the list is a type of container in Data Structures, which is used to store multiple data at the same time. Yes! For Loops using Sequential Data Types. The repeated passing of the iterator to the built-in next function returns successive items in the stream. Lists are used to store multiple items in a single variable. Don't make dynamically named variables. Instead, use a dict: And if you really want to have lst_ in each label: A slight variation to the other's dict-solutions is to use a defaultdict. I'm not understanding the question at all.
