To iterate through a list in Python, the most straightforward method is using aforloop. The syntax is simple:for item in list_name:, whereitemrepresents each element in the list, andlist_nameis the list you’re iterating over. For example, if you have a list of city names likecities ...
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...

Thanks. I havent ran through any complex data before. I've been relearning python due to the DevNet Associate and the OCG does not touch upon anything more than the basics. However, I did find the online DevNet learning labs does go into a little detail about nested data. https://develop...
Python Copy在上述代码中,我们定义了一个名为my_list的列表字典,并将其放入context字典中。然后,我们将context传递给render()函数,以便在模板中访问my_list。接下来,我们可以在模板中使用Django模板语言(Template Language)来遍历列表字典并进行显示。下面是my_template.html的示例代码:{...
