def f():
    global \
        analyze_featuremap_layer, \
        analyze_featuremapcompression_layer, \
        analyze_latencies_post, \
        analyze_motions_layer, \
        analyze_size_model

Output:

def f():
    global analyze_featuremap_layer, analyze_featuremapcompression_layer, analyze_latencies_post, analyze_motions_layer, analyze_size_model

Expected behavior

Output should be same as input.
