Im trying to run this Data function, I keep getting this error: TypeError: 'list' object is not callable. If someone can help me figure out what is the problem and what to change,

that would be helpful thanks

header ={}

def Data():

for heading inData[1:]:

splitting = heading.split(': ')

if len(splitting)>1 :

header = {splitting[0]:splitting[1] }

header.update(header)
