Using zip() method, you can iterate through two lists parallel as shown above. The loop runs until the shorter list stops (unless other conditions are passed). Example 2: Using itertools (Python 2+) import itertools list_1 = [1, 2, 3, 4] list_2 = ['a', 'b', 'c'] # loop ...
The dictionary unpacking operator (**) is an awesome feature in Python. It allows you to merge multiple dictionaries into a new one, as you did in the example above. Once you’ve merged the dictionaries, you can iterate through the new dictionary as usual....

Another way to iterate over Python iterables while returning both the index and corresponding value of elements is through the enumerate() function. Check out this example: fruits_list = ["Apple", "Mango", "Peach", "Orange", "Banana"] for index, fruit in enumerate(fruits_list): print(fr...
I have written a few simple python scripts, and was exposed to it during some course work in college. I am not sure how to write a script that will go through all the gbd (I think if i set the enviroment to the folder they are in then it will go through...
I want to iterate through a selected set of junctions, and for each one, perform the trace and calculate the field. However, calculate field appears to be running on the entire edge layer rather than the selection. As the model runs, I can see the selections being made in the map, ...
