A small demonstration of Python client side loop over Google Earth Engine objects (instead of using .map which can only run server side code)

client_side_loop.py

import ee

image_col = ee.ImageCollection(...)  # This should work with FeatureCollections and other GEE iterables

img_list = image_col.toList(image_col.size())

for img_idx in range(0, image_col.size().getInfo()):
    img = ee.Image(img_list.get(img_idx))
    ...
