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 ...
6. Iterate Python String using while loop A while loop in Python will iterate over a given sequence of elements until a given condition is met. In this case, we will loop through a string until the given condition is met. str = "SparkBy" print("String is:", str) # Iterate over the...
If you need to destructively iterate through a dictionary in Python, then .popitem() can do the trick for you: Python >>> likes = {"color": "blue", "fruit": "apple", "pet": "dog"} >>> while True: ... try: ... print(f"Dictionary length: {len(likes)}") ... item ...

In this post, we will see how to iterate through dictionary in python. You can use for key in dict.keys(): to iterate over keys of dictionary. 1 2 3 4 for key in dict.keys(): print(key) You can use for value in dict.values(): to iterate over values of dictionary. 1 2 3...
string = "Kinsta" for char in string: print(char) The code above iterates through the string “Kinsta” and prints each character on a new line. In each iteration, the variable char takes on the value of the current character in the string. The code should give the following output: K...
You can iterate through the Category field and append the value and corresponding OBJECTID to a dictionary. Then, remove duplicate values from the dictionary leaving only one OBJECTID for each category. You can then perform the selection based on the dictionary key. import arcpy...
