I just can't get the code to this part 4 to work:

return int(time[:2]) * 60 + int(time[2:])
def assessVehicle(customerReg, CID, SCL):

for customer in contents(customerReg):
if CID == getCID(customer):
customerRec = customer
break

service_costs = 0
service_time = 0
customer_costs = []
customer_vchl = getVehicle(customerRec)

if date.today().year - getYear(customer_vchl) > 5 and getMake(customer_vchl) != "Benz":
customer_costs.append(getFullHouseInfo(SCL, getMake(customer_vchl)))
service_costs += getServCost(SCL, getMake(customer_vchl), "FH" )
service_time += convertHHMMtoMin(getActivTime(SCL, getMake(customer_vchl), "FH"))
elif getMile(customer_vchl) > 100000:
customer_costs.append(getShocksInfo(SCL, getMake(customer_vchl)))
service_costs += getServCost(SCL, getMake(customer_vchl), "SH")
service_time += convertHHMMtoMin(getActivTime(SCL, getMake(customer_vchl), "SH"))

if int(getLastServDate(customer_vchl)) > 10:
customer_costs.append(getTyreInfo(SCL, getMake(customer_vchl)))
service_costs += getServCost(SCL, getMake(customer_vchl), "TY")
service_time += convertHHMMtoMin(getActivTime(SCL, getMake(customer_vchl), "TY"))

adjusted_cost = service_costs
treshold = 1.05 * float(getPayLimit(customer_vchl))
while customer_costs != []:
if adjusted_cost > treshold:
adjusted_cost -= cost(min(customer_costs))
customer_costs.remove(min(customer_costs))
else:
break

pickup_time = convertHHMMtoMin(getArivalTime(customerRec)) + service_time - 5

service_time = str(service_time//60).rjust(2, "0") + str(service_time % 60).rjust(2, "0")

for customer in contents(customerReg):
if CID == getCID(customer):
updateServiceTime(service_time, customer)
updateServiceCost(float(adjusted_cost), customer)
break
return "".join((str(pickup_time // 60).rjust(2,"0"), str(pickup_time % 60).rjust(2,"0")))
