@perfingo - you will be surprised what the result of your code is when the order of elements is different. Don't change list while iterating over it
assigning list comprehension to old_list is solving OP of removing elements and keeping the same variable
old_list = [ {'fname': 'Welcome.mp4', 'format': 'HEVC', 'width': 1920, 'height': 1080, 'duration': 118.867, 'framerate': 30.0, 'fsize_byte': 4095489}, {'fname': 'Line.mp4', 'format': 'HEVC', 'width': 1920, 'height': 1080, 'duration': 141.8, 'framerate': 25.0, 'fsize_byte': 4495620}, {'fname': 'tut.webm', 'format': 'VP9', 'width': 1152, 'height': 720, 'duration': 535.633, 'framerate': 23.976, 'fsize_byte': 17017448}, {'fname': 'CAPITAL.MP4', 'format': 'AVC', 'width': 1280, 'height': 720, 'duration': 284.3, 'framerate': 30.0, 'fsize_byte': 26107717}, ] for i, record in enumerate(old_list): if record['format'] != 'HEVC': old_list.pop(i) print(old_list)
Output:[{'fname': 'Welcome.mp4', 'format': 'HEVC', 'width': 1920, 'height': 1080, 'duration': 118.867, 'framerate': 30.0, 'fsize_byte': 4095489}, {'fname': 'Line.mp4', 'format': 'HEVC', 'width': 1920, 'height': 1080, 'duration': 141.8, 'framerate': 25.0, 'fsize_byte': 4495620}, {'fname': 'CAPITAL.MP4', 'format': 'AVC', 'width': 1280, 'height': 720, 'duration': 284.3, 'framerate': 30.0, 'fsize_byte': 26107717}]
it will work if you iterate over copy of the original list thoughassigning list comprehension to old_list is solving OP of removing elements and keeping the same variable
