Labmap.pbtxt file creation

Question

I am trying to create my labelmap.pbtxt, but the file is not created.

Here's the code

Train_Annotations_Path = "C:/Users/JAAD_dataset/Workspace/annotations/Annotations/Train"

Labels = {'-1': 'Not Crossing', 
          '0' : 'Not Crossing', 
          '1': 'Crossing'          
}
print(Labels)
print(type(Labels))

# Write to labelmap.pbtxt
with open(Train_Annotations_Path + '\labelmap.pbtxt' , 'w') as f:
    for label in Labels:
        print(label)
        f.write('item {\n')
        f.write('\{}:\'{}\'\n'.format(label[-1]))
        f.write('\{}:\'{}\'\n'.format(label[0]))
        f.write('\{}:\'{}\'\n'.format(label[1]))
        f.write('}\n')
    

Here's my annotation file (behaviour-specific as I am interested in crossing)

<?xml version="1.0"?>

-<ped_attributes>

<pedestrian traffic_direction="TW" signalized="n/a" old_id="pedestrian2" num_lanes="2" motion_direction="LONG" intersection="no" id="0_1_2b" group_size="1" gender="female" designated="ND" decision_point="26" crossing_point="-1" crossing="-1" age="adult"/>

<pedestrian traffic_direction="TW" signalized="n/a" old_id="pedestrian1" num_lanes="2" motion_direction="LONG" intersection="no" id="0_1_3b" group_size="1" gender="female" designated="ND" decision_point="363" crossing_point="-1" crossing="-1" age="senior"/>

</ped_attributes>

How to create labelmap.pbtxt file for the annotation behaviour XML?
